Physics conduction, convection and thermal radiation
define conduction
Conduction is the process by which heat energy is transmitted through collisions between neighboring molecules.
conduction is when hot things are likely to explode
define convection
Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it
convection is when a wave comes the current dosent flow
define thermal radiation
Thermal radiation is energy transfer by the emission of electromagnetic waves which carry energy away from the emitting object.

Which equation is correct?
energy = mass x specific latent heat x temperature
energy = mass x specific heat capacity x temperature
energy = mass x specific heat capacity x change in temperature
