If 30 kJ of heat flows out of a system and 15 kJ of work is done by the system, then what is the change in internal energy?  Express your answer in kJ.

The temperature of 2.03 mol of an ideal monoatomic gas is raised 16.4 K at constant volume.What is the change ΔEint in the internal energy of the gas?

The rate of heat flow through a slab is Pcond. If the slab thickness is doubled, its cross-sectional area is halved, and the temperature difference across it is doubled, then the rate of heat flow becomes:

Suppose object C is in thermal equilibrium with object A and with object B. The zeroth law of thermodynamics states:

A quantity of ideal gas at 11°C and 78 kPa occupies a volume of 3.3 m3. If the pressure is now raised to 290 kPa and the temperature is raised to 38.0°C, how much volume does the gas occupy? Assume no leaks.

Calculate the minimum amount of energy, in joules, required to completely melt 183 g of silver initially at 38.0°C. The melting point of silver is at 962°C. Its specific heat capacity is 236 J/kg·K and its latent heat of fusion is 105 kJ/kg.

Two particles are fixed to an x axis: particle 1 of charge -1.98 × 10-7 C is at the origin and particle 2 of charge +1.98 × 10-7 C is at x2 = 17.7 cm. Midway between the particles, what is the magnitude of the net electric field?
