10. The diagram shows a mercury manometer connected to a gas container. The density of mercury is 13 600 kg/m3 The gravitational field strength g is 10 N/kg. What is
the pressure difference between the gas in the container and the atmosphere?
A 27 200 Pa
B. 40 800 Pa
C 54 400 Pa
D. 81 600Pa

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
