Section 1 thermal energy and heat
What is the relationship between temperature and thermal energy?
When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object’s thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
What happens to thermal energy when the mass of an object?
The water in the beaker has twice as much thermal energy as the water in the glass has. If the temperature doesn’t change but the mass of the object increases, the thermal energy in the object increases. Heat Have you ever noticed that your chair felt warm when you sat down?
What happens to the energy released by water when heated?
The transfer of heat continues until the object and the water are the same temperature. The energy absorbed by the water can be calculated by measuring the water’s temperature change. The thermal energy released by the object equals the thermal energy absorbed by the water.
What is the thermal energy of water in a glass beaker?
The water in the beaker has twice as much thermal energy as the water in the glass has. If the temperature doesn’t change but the mass of the object increases, the thermal energy in the object increases.
How is the thermal energy of an object measured?
The transfer of heat continues until the object and the water are the same temperature. The energy absorbed by the water can be calculated by measuring the water’s temperature change. The thermal energy released by the object equals the thermal energy absorbed by the water.
What happens to thermal energy as particles move farther apart?
As particles move farther apart, their potential energy increases. As they move faster, their kinetic energy increases. Th ermal energyis the sum of the kinetic and potential energy of all the particles in an object. The figure shows that if either potential or kinetic energy increases, thermal energy increases.
How are temperature and kinetic energy related to each other?
Temperature and kinetic energy are related. Temperature is a measure of the average value of the kinetic energy of the particles in an object. As the temperature of something increases, the average speed of its particles increases.
Why does water have twice the thermal energy as glass?
The water in the beaker has twice as much thermal energy as the water in the glass has. If the temperature doesn’t change but the mass of the object increases, the thermal energy in the object increases.

Thermal energy and temperature are similar in that they both reflect the kinetic energy of particles moving matter. However, temperature reflects the average kinetic energy, whereas thermal energy reflects the total kinetic energy. Heat is the thermal energy that flows from something at a higher temperature to something at a lower temperature.

Thermal Expansion / o / s Recall that particles move faster and farther apart as the temperature rises. This separation of particles results in an expansion of the entire object, known as thermal expansion. Thermal expansion is an increase in the size of a substance when the temperature is increased. Substances also contract when they cool.
