A reaction is taking place inside a container of cross sectional
area 100cm2.
Because of the reaction, a piston is pushed up by a distance of
20.0 cm against an external pressure of 2.0 bar.
a) Calculate the work done by the system.
The temperature of the system is kept constant at 310K.
b) Calculate the work done by the system for this
process.

24. Suppose that an ideal gas is inside a container with a movable piston. Which of the following statements is true? 1) Increasing the temperature of the system while keeping the volume constant causes the gas to perform work. 2) When work is done by the system on the surroundings while temperature is kept constant, the pressure of the gas increases. 3) If temperature is kept constant, then decreasing the pressure of the gas causes a increase in volume 4)...

In a cylinder with a cross-sectional area A = 100 cm2 the air is at a Temperature t1 = 12C. The atmospheric pressure is equal to p1 = 101 kPa. At altitude h1 = 60 cm from the bottom of the cylinder there is an airtight, movable piston. By which distance will the piston sinks, when a weight of m = 100 kg falls on the piston and heats the air in the cylinder up to a temperature t2 =...

A piston/cylinder arrangement with an cross sectional area of 1 mạ contains carbon dioxide at 200 kPa and 290 K. The cylinder has a thick piston that initially held by a pin as shown in Figure 1. The metal piston has a density of 8000 kg/mº, standard acceleration of gravity, &c is 9.81 m/s and the atmospheric pressure is 101 kPa. The pin is now removed, allowing the piston to move and after a while the gas returns to 290...
