A cylinder contains 0.0100 mol of helium at T = 27.0°C. (a) How much heat is needed to raise the temperature to 67.0°C while keeping the volume constant? Draw a pV -diagram for this proccss. (b) If instead the pressure of the helium is kept constant, how much heat is needed to raise the temperature from 27.0°C to 67.0°C? Draw a pV -diagram for this process. (c) What accounts for the difference between your answers to parts (a) and (b)? In which case is more heat required? What becomes of the additional heat? (d) If the gas is ideal, what is the change in its internal energy in part (a)? In part (b)? How do the two answers compare? Why?

A system gains 3310 J of heat at a constant pressure of 1.38 × 105 Pa, and its internal energy increases by 4150 J. What is the change in the volume of the system, and is it an increase or a decrease?
An aluminum washer has an outer radius ro=1.3cm and an inner radius of ri=0.43cm. The temperature of the washer is raised from 282K to 630K. If the mass of the washer is 0.037g, the molar mass of aluminum is 26.98g/mol, and the molar specific heat of aluminum is 24.3J/mol-K, what is the change in the internal energy of the washer?
You add 18220 J of heat into a non-deformable container filled with a monatomic gas, raising the temperature from 313 K to 540 K. How many moles of gas are there in the container?
