A cold thermometer is pla io e(h0s.3xosced in a hot bowl of soup. Will th l3.xbjjpx5c z3zpk+:s v+ 7ohe temperature reading of the thermometer be the same xbz7 +33slhj+czjp :x po5.kv as the temperature of the hot soup before the measurement was made? Explain.
A. yes
B. no
参考答案: B
本题详细解析:
No. The hot soup must warm up the thermometer when tl4r w:rjp 3(b*qulztfzk:5 t 1hey come in contact, and so the final temperature of the thermometer and soup system will be less than the initial temperature of the soup. The thermometer reading will be lower than the original temperature of the soup. This is another situation where making the measurement affects the physical situation and causes error or uncertainty to enter iur l:l*t5p j( fbkq:r3tz4 zw1n the measurement.
