One of the most important microscopic properties of gas molecules is velocity. there are several different ways to describe statistically the average velocity of a molecule in a gas. the most obvious measure is the average velocity v⃗ avg. however, since the molecules in a gas are moving in random directions, the average velocity is approximately zero. another measure of velocity is (v2)avg, the average squared velocity. since the square of velocity is always

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
