Which of the following is a valid unit for specific heat?

Explanation:

The specific heat capacity is the amount of heat required to raise the temperature of 1mole or 1kg or 1g of substance by 1k or 1°C

This property is an intensive property of matter and does not depend on the quantity of matter present.

 Some of the unit of specific heat are;

J/g°C, J/kg°C, J/mol°C, J/molK , Cal/g°C

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
