What is the relationship between the kinetic energy of molecules in an object and the object's temperature?

as the temperature increases, the kinetic energy of the molecules increases

the kinetic energy always increases whether the temperature increases or decreases

the total kinetic energy of the molecules is not affected by a change in temperature

as the kinetic energy of the molecules decreases, the temperature increases

as the temperature increases, the kinetic energy of the molecules increases

Explanation: The kinetic energy of the molecules is the energy possessed by virtue of motion of the particles.

Kinetic energy of the particles is directly proportional to the temperature of the gas.

where T= temperature

R= gas constant

Thus if the temperature is increased, the molecules start moving more randomly and gain kinetic energy.

The production of the energy by the moving particle is called kinetic energy. The kinetic energy depends on the following:-

The kinetic energy of every state is different i.e the kinetic energy of the solid, liquid, and gas are different. The kinetic energy of the particles is directly proportional to the temperature of the gas.

T= temperature

R= gas constant

Thus if the temperature is increased, the molecules start moving more randomly and gain kinetic energy.

Hence, the correct option is A

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
