What is the difference between heat and temperature?
"Explain the difference between heat and temperature."
Learning objective:
Heat (Q) is the total thermal energy of particles in a substance. Temperature (T) is the average kinetic energy of the particles. Heat is measured in joules. Temperature is measured in degrees celsius. Heat is transferred through radiation, conduction or convection. Temperature is the measurement of the average kinetic energy of the particles.
Heat & Temperature:
Heat: thermal energy that is transferred from one object to another due to a difference in temperature. Temperature: a measure of the average kinetic energy of the particles in a substance, which is related to the heat energy of the substance. Heat and temperature are related, but they are not the same. Heat is a form of energy, while temperature is a measure of the average kinetic energy of the particles in a substance. Heat can cause a temperature change, but a change in temperature does not always mean that heat has been added or removed.

How are heat and temperature related?
- Heat and temperature are related, but they are not the same thing.
- Heat and temperature refer to different concepts with no relation.
- Heat and temperature are interchangeable terms.
Which one is measurable: heat or temperature?
- Temperature
- Neither heat nor temperature
- Both heat and temperature
Which one indicates the direction of thermal energy flow?
