How much energy, in joules, is released when 17 kilograms of granite is cooled from 45°C to 21°C?

Question and answer

327,992.8 J is released when 17 kilograms of granite is cooled from 45 C to 21 C. Solution: U = mCp(Tf-Ti); U = 17 kg (790 J/(kg-°C)) (21-45) = 322,320 Joules or 327,992.8 J.

If a certain mass of mercury has a volume of 0.002 m3 at a temperature of 20 C, the volume at 50 C will be 0.002010812 m3.

Solution: V =V [1 + (50-30)] = 0.002 [1 + 0.00018(30)] = 0.0020108 m³.

A mass of gas has a volume of 4 m3, a temperature of 290 K, and an absolute pressure of 475 kPa. When the gas is allowed to expand to 6.5 m3, its new temperature is 277 K. the absolute pressure of the gas after expansion is 279.2 KPa. P1V1/T1 =P2V2/T2 , 475 *4 /290 = 6.5 *P2 /277 , P2 = 475 *4 *277 /290 *6.5 = 526300 / 1885 = 279.2 KPa
