1
00:00:04,171 --> 00:00:04,894
喔!

2
00:00:05,232 --> 00:00:06,078
抱歉

3
00:00:07,186 --> 00:00:08,393
原諒我

4
00:00:08,701 --> 00:00:09,586
不不不

5
00:00:09,586 --> 00:00:11,024
不是上面

6
00:00:11,024 --> 00:00:12,481
我在下面啦

7
00:00:13,266 --> 00:00:14,289
對了

8
00:00:14,735 --> 00:00:15,627
嗨!

9
00:00:16,057 --> 00:00:17,850
我是個科學家

10
00:00:17,850 --> 00:00:21,191
我是來稍微改善你的...某些情況

11
00:00:21,484 --> 00:00:23,269
看見這些火了嗎?

12
00:00:25,475 --> 00:00:26,544
你曾經想過

13
00:00:26,544 --> 00:00:29,256
那些火花和火焰是怎麼來的嗎?

14
00:00:29,256 --> 00:00:31,135
我說的是火焰的顏色

15
00:00:31,135 --> 00:00:32,510
你也感覺的到溫度

16
00:00:32,510 --> 00:00:33,611
很熱對吧

17
00:00:33,611 --> 00:00:34,665
老天!

18
00:00:34,665 --> 00:00:36,184
被火焰包圍

19
00:00:36,184 --> 00:00:38,001
卻不知道他們是什麼東東一定很痛苦吧

20
00:00:38,001 --> 00:00:40,126
來,看看這個杯子蛋糕

21
00:00:40,126 --> 00:00:42,941
看到美味的蛋糕上面的火了嗎?

22
00:00:42,941 --> 00:00:44,351
你很喜歡杯子蛋糕吧?

23
00:00:44,628 --> 00:00:46,530
那我們靠近一點看吧

24
00:00:46,623 --> 00:00:48,083
太神奇了!

25
00:00:48,575 --> 00:00:50,924
如果我們看蛋糕上的火焰

26
00:00:50,924 --> 00:00:53,031
我們會先注意到…

27
00:00:53,031 --> 00:00:54,669
這些顏色!!

28
00:00:54,669 --> 00:00:57,440
最底下是藍的

29
00:00:57,856 --> 00:01:00,634
越往上越黃…橘…紅

30
00:01:00,634 --> 00:01:02,492
還有,它非常的熱

31
00:01:02,492 --> 00:01:04,767
為什麼它會熱?

32
00:01:05,053 --> 00:01:06,903
關於這個問題

33
00:01:06,903 --> 00:01:08,974
你要先了解一些基本的東西

34
00:01:08,974 --> 00:01:10,377
你看見的所有物體都是

35
00:01:10,377 --> 00:01:12,263
由一個個叫原子小東西組成的

36
00:01:12,263 --> 00:01:15,911
這些小東西是組成所有物體的基礎!

37
00:01:15,911 --> 00:01:17,673
它們非常非常小

38
00:01:17,811 --> 00:01:18,726
再小一點

39
00:01:18,926 --> 00:01:19,870
再小一點

40
00:01:20,162 --> 00:01:21,793
再來!

41
00:01:21,900 --> 00:01:23,470
嘿!看不見了

42
00:01:23,470 --> 00:01:25,192
它們超級小

43
00:01:25,346 --> 00:01:26,538
就是這樣!

44
00:01:26,846 --> 00:01:30,133
所有你想的到的都是原子構成的

45
00:01:30,948 --> 00:01:33,568
對,這個空調是原子組成的

46
00:01:34,279 --> 00:01:36,515
還有這美味的冰棒

47
00:01:37,007 --> 00:01:39,425
這冰水也都是原子

48
00:01:39,425 --> 00:01:42,723
所有東西都是幾十億幾千億的原子結合的

49
00:01:43,213 --> 00:01:43,713
回到這邊

50
00:01:43,713 --> 00:01:46,488
這個蠟燭和火焰是三種原子做的

51
00:01:46,488 --> 00:01:47,383
碳

52
00:01:47,383 --> 00:01:48,917
氫

53
00:01:48,917 --> 00:01:50,279
氧

54
00:01:50,279 --> 00:01:52,505
碳跟氫被鎖在一起

55
00:01:52,505 --> 00:01:54,222
變成固體的蠟和燈芯

56
00:01:54,222 --> 00:01:57,154
氧就是我們周圍的氣體

57
00:01:58,169 --> 00:01:58,964
正常情況下

58
00:01:58,964 --> 00:02:01,198
氧跟蠟燭沒有任何關係

59
00:02:01,198 --> 00:02:03,398
它只是撞擊表面

60
00:02:03,398 --> 00:02:05,256
卻沒造成實際傷害

61
00:02:05,256 --> 00:02:06,931
但我們加上熱呢

62
00:02:06,931 --> 00:02:09,064
氧分子發瘋了

63
00:02:09,064 --> 00:02:11,214
它們像瘋子一樣搖動著蠟燭

64
00:02:11,214 --> 00:02:15,692
最後最後,在力量的撞擊下衝出來

65
00:02:15,692 --> 00:02:18,050
它們離開蠟燭變成氣體

66
00:02:18,050 --> 00:02:19,629
然後跟氧氣結合

67
00:02:19,629 --> 00:02:21,629
啊喔!好像有麻煩了

68
00:02:21,629 --> 00:02:24,960
這個東西有個美麗的科學名字

69
00:02:24,960 --> 00:02:27,375
熱解

70
00:02:27,375 --> 00:02:29,542
它是形成火焰的基本要素

71
00:02:29,542 --> 00:02:32,263
是燃料變成氣體的過程

72
00:02:33,294 --> 00:02:36,341
我們來看看這些熱氣結合會變成什麼吧!

73
00:02:36,341 --> 00:02:38,116
各位先生女士

74
00:02:38,116 --> 00:02:40,298
這個角落的先生曾是固體

75
00:02:40,298 --> 00:02:41,997
現在成了氣體

76
00:02:41,997 --> 00:02:43,979
它是西邊的燃料!

77
00:02:43,979 --> 00:02:45,168
然後這邊的角落

78
00:02:45,168 --> 00:02:45,952
不只一個喔

79
00:02:45,952 --> 00:02:48,053
是兩組的氧氣!

80
00:02:48,053 --> 00:02:49,119
預備

81
00:02:49,119 --> 00:02:50,386
開始!

82
00:02:51,755 --> 00:02:55,170
一旦原子被強烈撞擊

83
00:02:55,401 --> 00:02:58,372
它們便會釋放出藍光

84
00:02:58,372 --> 00:03:00,886
因為很多原子都被這樣撞擊

85
00:03:00,886 --> 00:03:03,187
它們放出很多藍光

86
00:03:03,187 --> 00:03:06,100
這就是我們看到的藍色火焰

87
00:03:06,100 --> 00:03:07,903
還有另外一個科學字眼

88
00:03:07,903 --> 00:03:08,756
看好了

89
00:03:08,833 --> 00:03:10,568
化學發熒光!

90
00:03:10,568 --> 00:03:12,063
我知道,很難唸

91
00:03:12,063 --> 00:03:13,117
再一次

92
00:03:13,117 --> 00:03:14,521
化學發熒光

93
00:03:14,521 --> 00:03:16,475
這是原子重組射出的光

94
00:03:16,475 --> 00:03:18,877
它就是火焰成藍色的原因了

95
00:03:19,585 --> 00:03:21,586
這藍光不是燙的喔!

96
00:03:21,586 --> 00:03:22,568
等等!

97
00:03:23,276 --> 00:03:25,880
這火焰很燙的

98
00:03:26,126 --> 00:03:28,543
但如果藍光不是熱源

99
00:03:28,543 --> 00:03:30,868
那火為什麼會熱呢?

100
00:03:30,976 --> 00:03:33,826
記得燃料原子嗎?

101
00:03:33,826 --> 00:03:35,226
氧原子呢?

102
00:03:35,226 --> 00:03:39,309
它們重組出像水一樣的東西還有二氧化碳

103
00:03:39,309 --> 00:03:40,544
當它們重組時

104
00:03:40,544 --> 00:03:42,009
彼此互相碰撞

105
00:03:42,009 --> 00:03:43,939
每個撞擊

106
00:03:43,939 --> 00:03:46,676
新成品都像瘋了一樣搖晃

107
00:03:46,676 --> 00:03:48,178
重組完成後

108
00:03:48,178 --> 00:03:51,714
我們有很多劇烈搖晃的新品

109
00:03:51,714 --> 00:03:54,835
如果有東西接近這些原子

110
00:03:54,945 --> 00:03:57,261
它們也一樣會搖到瘋掉

111
00:03:57,261 --> 00:03:58,609
就像我們手中的原子

112
00:03:58,609 --> 00:04:00,592
這就是熱量

113
00:04:00,592 --> 00:04:03,323
這個過程叫做氧化

114
00:04:03,430 --> 00:04:07,464
這是氧原子跟其他原子結合產生新分子的過程

115
00:04:07,464 --> 00:04:09,898
就是火焰這麼熱的原因

116
00:04:09,898 --> 00:04:10,966
問題來了

117
00:04:10,966 --> 00:04:13,586
為什麼大多的火焰呈黃、橘、紅色?

118
00:04:13,586 --> 00:04:15,678
記得上一場決鬥嗎?

119
00:04:15,678 --> 00:04:19,378
我們有一組燃料跟兩組氧分子

120
00:04:19,378 --> 00:04:21,361
是他們讓火焰變熱的

121
00:04:21,361 --> 00:04:23,043
但是只有藍火

122
00:04:23,043 --> 00:04:25,925
來看看氧氣不足會發生什麼事

123
00:04:25,925 --> 00:04:27,558
我們來拿走一些

124
00:04:27,558 --> 00:04:28,710
各位先生女士

125
00:04:28,710 --> 00:04:31,480
氧氣不足到底會怎麼樣呢?

126
00:04:32,899 --> 00:04:33,938
喝!

127
00:04:33,938 --> 00:04:34,438
這是什麼!?

128
00:04:34,438 --> 00:04:37,074
只剩下一個碳原子!

129
00:04:37,074 --> 00:04:37,976
還好

130
00:04:37,976 --> 00:04:40,491
其他剩下的碳都來給他支援了

131
00:04:40,491 --> 00:04:42,692
它們形成很大的黑色顆粒

132
00:04:42,692 --> 00:04:44,211
煤灰

133
00:04:44,211 --> 00:04:44,727
好吧

134
00:04:44,727 --> 00:04:45,591
它們不大

135
00:04:45,591 --> 00:04:46,296
它們超小的

136
00:04:46,296 --> 00:04:47,458
小到我們看不見

137
00:04:47,458 --> 00:04:49,094
但對單一個原子來說

138
00:04:49,094 --> 00:04:50,611
它們很大了

139
00:04:50,611 --> 00:04:52,161
超級大!

140
00:04:52,161 --> 00:04:53,995
我知道你在想什麼

141
00:04:53,995 --> 00:04:57,295
為什麼黑色顆粒會變成黃色的火

142
00:04:57,295 --> 00:04:58,478
我會告訴你

143
00:04:58,478 --> 00:05:00,347
但首先,我需要一個又大又黑的東西

144
00:05:00,347 --> 00:05:01,979
例如這支草叉

145
00:05:01,979 --> 00:05:03,101
魔王陛下

146
00:05:03,101 --> 00:05:03,770
不好意思

147
00:05:03,770 --> 00:05:06,726
可以把你的草叉放進超熱的火裡嗎?

148
00:05:06,726 --> 00:05:07,944
非常感謝

149
00:05:07,944 --> 00:05:11,110
草叉會像海綿一樣的吸熱氣

150
00:05:11,110 --> 00:05:12,827
為了釋放能量

151
00:05:12,827 --> 00:05:15,027
它們必須發光

152
00:05:15,027 --> 00:05:17,644
它們越熱就會越亮

153
00:05:18,475 --> 00:05:20,951
我們的煤灰也是一樣的

154
00:05:20,951 --> 00:05:23,315
他們把熱原子的熱氣吸進來

155
00:05:23,315 --> 00:05:24,575
越來越亮

156
00:05:24,575 --> 00:05:25,492
越來越亮

157
00:05:25,492 --> 00:05:27,826
一直到變成這樣

158
00:05:27,826 --> 00:05:31,008
因為它們是幾百萬個的發光體

159
00:05:31,008 --> 00:05:32,357
散發熱光

160
00:05:32,357 --> 00:05:33,759
我們就看到了黃光

161
00:05:33,759 --> 00:05:34,536
喔!

162
00:05:34,536 --> 00:05:36,783
這叫白熾

163
00:05:36,783 --> 00:05:38,866
就是當它們熱到發光的時候

164
00:05:38,866 --> 00:05:41,107
這就是它們變黃的原因

165
00:05:41,307 --> 00:05:42,354
就這樣

166
00:05:42,354 --> 00:05:43,623
這就是火焰

167
00:05:43,623 --> 00:05:44,389
我說

168
00:05:44,389 --> 00:05:46,170
誰知道一個杯子蛋糕也可以這麼有趣

169
00:05:46,170 --> 00:05:46,973
記住

170
00:05:46,973 --> 00:05:49,823
首先你會失去很多燃料然後得到氣體

171
00:05:49,823 --> 00:05:51,571
在下一階段完成前

172
00:05:51,571 --> 00:05:52,738
它們放出藍光

173
00:05:52,738 --> 00:05:54,305
整個結束後

174
00:05:54,305 --> 00:05:55,838
它會放熱

175
00:05:55,838 --> 00:05:58,624
剩下的炭灰會變成紅色、橘色、黃色

176
00:05:59,224 --> 00:06:01,327
就像神奇的火焰歌

177
00:06:01,327 --> 00:06:04,016
美妙的旋律那樣

178
00:06:04,278 --> 00:06:05,993
他是這麼唱的

179
00:06:05,993 --> 00:06:08,093
失去燃料後

180
00:06:08,093 --> 00:06:09,851
他成了氣體

181
00:06:09,851 --> 00:06:12,060
下階段完成前

182
00:06:12,060 --> 00:06:13,811
原子散著藍光

183
00:06:13,811 --> 00:06:15,978
一切結束後

184
00:06:15,978 --> 00:06:17,828
它放熱

185
00:06:17,828 --> 00:06:20,244
剩下的碳閃亮著

186
00:06:20,244 --> 00:06:22,261
黃、橘、紅

187
00:06:22,261 --> 00:06:24,192
失去燃料後

188
00:06:24,192 --> 00:06:25,861
他成了氣體

189
00:06:25,861 --> 00:06:27,828
下階段完成前

190
00:06:27,828 --> 00:06:29,695
原子散著藍光

191
00:06:29,695 --> 00:06:31,843
一切結束後

192
00:06:31,843 --> 00:06:33,744
它放熱

193
00:06:33,744 --> 00:06:36,061
剩下的碳閃亮著

194
