Final answer:
To make liquids become a gas, you must provide them with heat energy. This is part of the vaporization process, where heat energy is used to overcome molecular bonds in the liquid, allowing it to transform into gas. Chemical potential energy in substances like gasoline is released as heat and mechanical energy during combustion.
Step-by-step explanation:
To make them gas, you have to give liquids heat energy. When a liquid receives sufficient heat energy, it gains enough kinetic energy for its particles to overcome their intermolecular forces and move freely as a gas. This process is termed vaporization, and it is essentially the conversion of potential energy within the liquid into kinetic energy that allows the liquid particles to enter the gaseous phase. Chemical potential energy is stored in the molecular bonds of substances, and when it comes to liquids, providing heat energy helps in breaking these bonds to transform into a gas.
For example, the chemical potential energy stored in gasoline is released as both heat and work when gasoline is burned in an engine. This conversion of forms of energy is essential for the functionality of engines. As the gasoline combusts, this chemical energy is converted into mechanical energy, which is a form of kinetic energy, subsequently used to move the pistons and propel the car forward.
