What is Relation between temperature and kinetic energy?

Answer 1

In an ideal gas of monatomic particles, the average kinetic energy is

<K>=(3/2)*k*T

In a more general ideal gas, the average energy of each particle is

<K>=(d/2)*k*T

where d is the number of degrees of freedom. There isn't a clear distinction between kinetic and potential energy for general degrees of freedom.

For normal (non-negative) temperatures, as temperature increases, so does energy. The exact relation depends on the entropy of the system.

T=dU/dS, where d is the partial derivative.

Answer 2

All atoms and molecules vibrate. A vibration is a movement back and forth, sometimes like simple harmonic oscillation. Kinetic Energy is the energy associated with motion, and is equal to .5mv^2. So, temperature is a measurement of the average kinetic energy of a molecule. Or in other words, a higher temperature something means the molecules are vibrating back and forth more quickly, ie, more kinetic energy. Austin

Answer 3

If you double the temperature (on the Kelvin scale) then you double the kinetic energy

Answer 4

How does the kinetic energy of solids, liguids, and gases compare

Answer 5

It is a measurement of the motion of the particles that compose whatever is being measured.

Answer 6

absolute temperature scale in kelvin (degrees).

Answer 7

i don't know. i was hoping someone else flippin' answered it.

Answer 8

Kelvin
