What is the main difference between a gas and a plasma?

Gases are not ionized while plasma is.

A gas contains uncharged atoms, while a plasma contains ions and free electrons, both of which are charged particles.

  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
