Solution: The temperature of 5.0 moles of an ideal gas is increased from 100°C to 300°C. If this is done at constant volume, 3.0 x 104 J of heat energy flows into the gas. If the same temperature change is carried out at constant pressure, the heat flow into the gas is (a) 3.0 x 104 J (b) less than 3.0 x 104 J (c) greater than 3.0 x 104 J

Problem

The temperature of 5.0 moles of an ideal gas is increased from 100°C to 300°C. If this is done at constant volume, 3.0 x 104 J of heat energy flows into the gas. If the same temperature change is carried out at constant pressure, the heat flow into the gas is

(a) 3.0 x 104 J

(b) less than 3.0 x 104 J

(c) greater than 3.0 x 104 J
