In a well-insulated container, 3.5 kg of water and 2.0 kg of ice are in thermal equilibrium at 0 °C. How much heat is required to bring the system to thermal equilibrium at 35 °C?

A heat engine is used to lift a 4500-kg load to a height of 3 m at a constant speed. During the lifting process, the engine received 400,000 J of heat from the fuel burned in its interior. What is the efficiency of the engine?

An ideal gas initially has a volume of 0.036 m3, an absolute pressure of 2 atm, and a temperature of 33 °C.  The pressure becomes 1 atm when the volume of the container is decreased to 0.012 m3.  What is the final temperature of the gas?

A system containing an ideal gas at a constant pressure of 1.55 × 105 Pa gains 1520 J of heat.  During the process, the internal energy of the system increases by 2100 J.  What is the change in volume of the gas?

An ideal gas initially has a volume of 0.048 m3, an absolute pressure of 4 atm, and a temperature of 47 °C.  The pressure becomes 1 atm when the volume of the container is decreased to 0.024 m3.  What is the final temperature of the gas?

A rock weighs 20 N in air and 15 N when completely submerged in a fluid with a density of 800 kg/m3.   Determine the density of the rock.

A rock weighs 20 N in air and 15 N when completely submerged in a fluid with a density of 800 kg/m3.   Determine the density of the rock.

What is the pressure difference between the street level and the roof of a 400 m high tower?  (Assume the density of air is 1.29 kg/m3 )

A heat engine operates between a hot reservoir at 2500 K and a cold reservoir at 500 K.  During each cycle, 2.5 × 105 J of heat is removed from the hot reservoir and 5 × 104 J of work is performed. Determine the maximum possible efficiency of this engine.
