Question

What is heat in chemistry?

Answer 1

Heat: Heat is a type of energy that is transferred from the higher temperature region to the lower temperature region.

• The SI unit is Joule (J).
• The phase change also happens due to heat.
• The heat is calculated by an equation:

$\mathrm{q}={\mathrm{mC}}_{\mathrm{p}}∆\mathrm{T}$

where q is heat quantity, m is the mass of a material, ${\mathrm{C}}_{\mathrm{p}}$ is either molar or specific heat capacity, and $∆\mathrm{T}$ is the temperature difference.
