Top.1 Electrical Heating Control Devices

What is the difference between temperature and heat?

Temperature is physically measurable average kinetic energy of molecules in a substance, heat is transfer of thermal energy

What is the difference between conduction, convection, radiation?

Conduction (solid): fast-moving molecules in direct contact with slow-moving molecules, Convection (liquid/gas): heat transfer via movement of liquid/gas due to temperature differences, Radiation: heat transfer via electromagnetic waves

What is thermal conductivity?

How readily a material conducts heat. High conductivity: transfers heat well, low conductivity: transfers heat poorly
