A gas expands isothermally and reversibly from a volume V to 2V. If the initial pressure is P, what is the final pressure?
A source supplies heat to a system at the rate of 1000 W. If the system performs work at a rate of 200 W, what is the rate at which internal energy of the system increases?
In an isobaric process, 200 J of heat is supplied to a gas. The gas does 50 J of work. What is the change in internal energy?
An ideal gas expands from 2 L to 6 L at a constant temperature of 300 K. Calculate the work done by the gas if pressure remains constant at 2 atm. (1 atm = $1.013 \times 10^5$ Pa)

A cyclic process is shown in the p-T diagram. Which of the curves shows the same process on a p-V diagram? 



A particle starts moving rectilinearly at time t=0 such that its velocity v changes with time t according to the equation v=t²-t, where t is in seconds and v is in m/s. Find the time interval for which the particle retards.
A sample of gas expands from volume V₁ to V₂. The amount of work done by the gas is greatest when the expansion is:
