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?

The heat capacity at constant volume and the heat capacity at constant pressure have different values because:
