heat and pressure

Heat is the transfer of energy between objects due to temperature difference, making molecules move faster and warmer. Pressure is the force exerted per unit area when particles collide within a container or surface; higher pressure results from more frequent or forceful collisions. Both depend on particle movement: increased heat boosts molecular activity, raising pressure if volume is constant. Conversely, applying pressure can compress materials, affecting their temperature and state. Understanding heat and pressure helps explain phenomena like weather, engines, and natural processes in Earth's interior.
