How we can prove that heat can perform task
Answers
In chemistry, alcohol is an organic compound that carries at least one hydroxyl functional group (−OH) bound to a saturated carbon atom. The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks.

Heat Changes the Temperature of Objects
Q. What does heat do?
First, it changes the temperature of an object. If heat is transferred from an object to the surroundings, then the object can cool down and the surroundings can warm up. When heat is transferred to an object by its surroundings, then the object can warm up and the surroundings can cool down. Heat, once absorbed as energy, contributes to the overall internal energy of the object. One form of this internal energy is kinetic energy; the particles begin to move faster, resulting in a greater kinetic energy. This more vigorous motion of particles is reflected by a temperature increase. The reverse logic applies as well. Energy, once released as heat, results in a decrease in the overall internal energy of the object. Since kinetic energy is one of the forms of internal energy, the release of heat from an object causes a decrease in the average kinetic energy of its particles. This means that the particles move more sluggishly and the temperature of the object decreases. The release or absorption of energy in the form heat by an object is often associated with a temperature change of that object. This was the focus of the Thermometers as Speedometers. What can be said of the object can also be said of the surroundings. The release or absorption of energy in the form heat by the surroundings is often associated with a temperature change of the surroundings. We often find that the transfer of heat causes a temperature change in both system and surroundings. One warms up and the other cools down.
