How do you define 'heat' and 'temperature'

Heat and temperature are related but very different.

Explanation:

Heat: The total energy of molecular motion in a substance

Temperature: A measure of the average energy of molecular motion in a substance

Examples

Heat                                                             Temperature

-Heat is a form of energy that can             -The degree of hotness and

transfer from hot body to cold body           coldness of the body

-Heat flows from hot body to cold             -It rises when heated and falls down

body                                                              when an object is cooled down

-Total kinetic energy and potential            -Temp. is the average kinetic

energy obtained by molecules in                energy of molecules in a

an object                                                        substance

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
