Question

On what does internal energy depend?

a) Temperature and pressure.

b) Volume and temperature.

c) Pressure and volume.

d) Temperature, pressure, and volume.

Answer 1

The internal energy of a system depends on temperature, pressure, and volume. When a large amount of energy is added to or extracted from a system, it can cause changes in the gas's volume and pressure, leading to an increase or decrease in internal energy.

Step-by-step explanation:

The internal energy of a system depends on temperature, pressure, and volume. The internal energy of a system depends on temperature, pressure, and volume. When a large amount of energy is added to or extracted from a system, it can cause changes in the gas's volume and pressure, leading to an increase or decrease in internal energy.

The dependence on temperature is easily understood because the kinetic energy of atoms or molecules is proportional to the absolute temperature. The internal energy is also influenced by the pressure and volume of the system.

For example, when a large amount of energy is added to a system, it can cause a decrease in the gas's volume, pressure, or both, resulting in an increase in internal energy.
