A cylinder containing an ideal gas has a volume of 2.6 m3 and a pressure of 1.5× 105 Pa at a temperature of 300 K. The cylinder is placed against a metal block that is maintained at 900 K and the gas expands as the pressure remains constant until the temperature of the gas reaches 900 K. The change in internal energy of the gas is +6.0× 105 J. How much heat did the gas absorb?

a. 1.4E+6 J

b. 7.8E+5   J

c. 6.0E+5 J

d. 3.4E+5 J

e. 0

A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 3.00 L and the pressure is initially 105 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 65.0 J of work is then done on the piston, compressing the gas (in other words, the gas does −65.0 J of work). The work is done very slowly so that the gas maintains a...
