37. Out of a solid, liquid and gas of the same mass and at the same temperature, which one has the greatest internaienergy and which one least? Justify

Answer»

The molecules in a gas are the most energetic. Due to weak intermolecular forces, the particles of a gas are free and possess most kinetic energy. A solid is rigid. Due to srong intermolecular forces of attraction, the particles of a solid are held tightly together and have the least kinetic energy.
