Question

Kinetic energy of molecular motion appears as
(a) pressure
(b) potential energy
(c) temperature
(d) all of these

Answer 1

Answer: temperature

Explanation:

Answer 2

Answer:

Temperature represents the kinetic energy of molecular motion.

Explanation:

The molecular motion:

• Every molecule is always moving. Liquid molecules have more freedom of movement than solid molecules, while gas molecules have the most flexibility of movement.

• According to the kinetic energy theory, increasing the temperature of a gas increases the average kinetic energy of the molecule, which causes the molecules to move faster.

• The outward pressure of the gas is enhanced as a result of the increased velocity.

• The average kinetic energy of translation per gas molecule is proportional to temperature, as follows:

                             KE=3/2kBT

Where E=kinetic energy

kB= Boltzmann constant

T=Temperature

Option 3 is true because the average kinetic energy of the gas molecule is directly proportional to the absolute temperature of the gas, as shown by the preceding equation.

• It is unaffected by the gas's pressure, volume, or type. The translational motion of molecules is increased when the temperature rises.
