The heat exchange in chemical reactions is due to a change in: kinetic energy enthalpy temperature physical properties

Option (b) is the correct answer.

Explanation:

Enthalpy is defined as the exchange of heat in chemical reactions. Enathlpy is denoted by .

When is positive then it means the reaction is endothermic whereas if   is negative then it means the reaction is exothermic.

Whereas kinetic energy is the energy obtained due to motion of atoms. When we increase temperature then generally atoms gain kinetic energy.

Temperature is the measure of thermal energy of a reaction. On the other hand, physical properties are the properties that does not change the chemical composition of a substance.

Therefore, we can conclude that the heat exchange in chemical reactions is due to a change in enthalpy.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
