15 pts! Explain how the absorption of energy (heating) affects the speed of the particles in a substance.

See explanation

Explanation:

Temperature has been severally defined as the measure of the average kinetic energy of the molecules of a body. Heat is a form of energy that exists due to temperature difference.

Given a body whose molecules has a speed = (3RT/M)^1/2; this implies that for a given mass of the substance, the velocity of its particles depends on the temperature of the substance.

However, absorption of heat increases the temperature of the body. Therefore, when heat is absorbed, the temperature increases and the speed of the particles of a substance increases according to the relation above.

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.
