Temperature & Heat
13. At 30 °C the volume of an aluminum sphere is 30 cm³. The coefficient of linear
expansion is 24 x 10 C¹. If the final volume is 30.5 cm³, what is the final temperature of
the aluminum sphere? Assume B = 3 a
14. A 500-gram cube of lead is heated from 25 °C to 75 °C. How much energy was required
to heat the lead? The specific heat of lead is 0.129 J/g-°C.
15. How much heat is required to convert 135 g of ice at -15 °C into water vapor at 120 °C?
(Assume c of steam = 1.996 J/g-°C, c of water = 4.1858 J/g-°C, c of ice =2.090 J/g-°C.
Lv of water = 540 cal/g & Lf of water = 80 cal/g)
