Question: What is heat?

Heat is a form of energy It can be transferred but not destroyed and is the energy that flows from a hotter object to a less hot to a cold one due to a temperature difference between the objects, meaning an object would continually be cold unless it acquires heat from a hot object or source through heat transfer mechanisms which can be conduction, convection, or radiation, and it is measured usually in calories or joules.

Question: In which direction does heat flow?

Heat practically flows from a hot object which has a higher temperature to a cold object which temperature is lower through conduction, convection, radiation.

Question: What does thermochemistry involve?

Thermochemistry is the study of heat as a form of energy making it possible to determine the relationship between heat and chemical reactions which is necessary to know if a reaction would take place or not.

Question: How do we measure heat?

it is measured usually in calories or joules using thermometers and pyrometers.
