What is temperature in terms of kinetic energy?
Keeping this in view, what is the connection between temperature and kinetic energy?
Kinetic energy is the energy that an object has because of its motion. The molecules in a substance have a range of kinetic energies because they don't all move at the same speed. As a subtance absorbs heat the particles move faster so the average kinetic energy and therefore the temperature increases.
Accordingly, is temperature just kinetic energy?
Temperature is the measurement of the average kinetic energy of particles, not just their speed. Kinetic energy depends on mass as well as speed. However, the particles in a doorknob have more mass and they can have the same amount of kinetic energy as particles in air.
As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase.
