c) the work non flow in kJ

One mole of an ideal gas is heated slowly so that it triples its volume and pressure, in such a way that the pressure of the gas is directly proportional to its volume (linear relationship). Whats the work consumed by the gas?

Gas in a container is at a pressure of 1.9 atm and a volume of 6.0 m3. (a) What is the work done on the gas if it expands at constant pressure to twice its initial volume? J(b) What is the work done on the gas if it is compressed at constant pressure to one-quarter of its initial volume? J

11) a) Derive an expression relating the temperature and volume for an adiabatic process of an ideal monoatomic gas for 2 different states.

A gas undergoes an isothermal process at a constant temperature of 300 K. If the initial volume of the gas is 2 L and the final volume is 8 L, calculate the work done by the gas during the process.

How much heat transfer (in J) occurs from a system if its internal energy decreased by 290 J while it was doing 43.0 J of work? (Enter the magnitude.)

The entropy of a block of ice increases by 75 J/K as it warms from -33 degrees Celsius to 0 degrees Celsius. What is the mass of the block of ice?

As an ideal gas expands at constant pressure from a volume of0.74 m3 to a volume of 2.3 m3 it does 93 J of work. What is the gaspressure during this process?

(a) A large electrical power facility produces 1600 MW of “waste heat,” which is dissipated to the environment in cooling towers by warming air flowing through the towers by 5.00ºC . What is the necessary flow rate of air in         m3 /s ? (b) Is your result consistent with the large cooling towers used by many large electrical power plants?

Does a gas do any work when it expands adiabatically? If so, what is the source of the energy needed to do this work?
