Heat is a form of energy that is transferred from one object to another due to a difference in temperature. It is typically measured in units of Joules (J) or calories (cal).
Temperature is a measure of the average kinetic energy of the particles in a substance, while heat is the total amount of energy transferred between two objects due to a temperature difference. In other words, temperature is a measure of how hot or cold something is, while heat is a measure of the transfer of thermal energy.
The amount of heat transferred depends on the temperature difference between the two objects, the specific heat capacity of the materials involved, and the amount of time the objects are in contact.
Heat can be transferred through three main methods: conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between two objects, convection is the transfer of heat through the movement of fluids, and radiation is the transfer of heat through electromagnetic waves.
Heat can be measured using a thermometer, which detects changes in temperature, or a calorimeter, which measures the energy absorbed or released during a chemical reaction. In addition, heat can also be quantified using mathematical equations, such as the first law of thermodynamics.
