Time & Temperature (NYC)第 56 / 240 题

Using the boiling-point method to calibrate a thermometer at sea level in NYC, the device should read:

a.180°F
b.165°F
c.212°F
d.200°F

解析

At sea level, pure water boils at 212°F, so a thermometer held in boiling water should read 212°F; if not, you adjust it. NYC is at sea level, so no altitude correction is needed. The ice-point method (32°F) is generally preferred because it is safer and easier.
