A. yes
B. no
参考答案: B
本题详细解析:
No. The hot soup must warm uzsp 7yh- 1g1t0su(fxh p the thermometer when they 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 s7phy- fshg1 xt 1z(0uphysical situation and causes error or uncertainty to enter in the measurement.
