Which body will give up more heat: mercury in a thermometer or mercury in a 0.5 liter bottle when the temperature drops by 2 degrees Celsius?
The mass of mercury in a thermometer is 2 g, in a bottle – 6773 g.
Qgr = c * 16 ° C * 2 g;
Qbut = c * 2 ° C * 6773 g.
Qbut / Qgr = (c * 2 ° C * 6773 g) / (c * 16 ° C * 2 g) ≈ 432.
Answer: The bottle will give more heat.
