A student runs two experiments with a constant-volume "bomb" calorimeter containing 1200. g of water (see sketch at
right).
Calculating heat of reaction from bomb calorimetry data
First, a 5.000 g tablet of benzoic acid (C6H,CO₂H) is put into the "bomb" and burned completely in an excess of
oxygen. (Benzoic acid is known to have a heat of combustion of 26.454 kJ/g.) The temperature of the water is
observed to rise from 16.00 °C to 38.96 °C over a time of 9.2 minutes.

4.
Next, 5.730 g of acetaldehyde (C₂H₂O) are put into the "bomb" and similarly completely burned in an excess of
oxygen. This time the temperature of the water rises from 16.00 °C to 42.19 °C.

The power of sunlight reaching each square meter of the Earth’s surface on a clear day in the tropics is close to 1 000 W. On a winter day in Manitoba, the power concentration of sunlight can be 100 W/m2. Many human activities are described by a power per unit area on the order of 102 W/m2or less. (a) Consider, for example, a family of four paying $66 to the electric company every 30 days for 600 kWh of energy carried by electrical transmission to their house, which has floor dimensions of 13.0 m by 9.50 m. Compute the power per unit area used by the family. (b) Consider a car 2.10 m wide and 4.90 m long traveling at 55.0 mi/h using gasoline having “heat of combustion” 44.0 MJ/kg with fuel economy 25.0 mi/gal. One gallon of gasoline has a mass of 2.54 kg. Find the power per unit area used by the car. (c) Explain why direct use of solar energy is not practical for running a conventional automobile. (d) What are some uses of solar energy that are more practical?
(b)
Heat is generated by the core of a nuclear reactor, this heat is
removed by pumping cooling water through the core at a rate
of 45 x 106 kg/h to generate steam. Cooling water, initially at
30 °C is continuously pumped through the reactor so that the
outlet temperature is 748 °C and the core temperature remains
constant. Calculate the rate of heat generated by the core of a
nuclear reactor (in joules per second).
(The specific heat capacity of ice

water = 4190 Jkg K; steam
2010 Jkg K. The latent heat
of fusion of water is 334 kJ kg: latent heat of vaporisation of
