1. What is thermal energy?
Thermal energy is the energy that is created by the movement of particles within a substance. This energy can be transferred from one object to another and can cause changes in temperature and state of matter.
2. What is temperature?
Temperature is a measure of the average kinetic energy of the particles in a substance. The higher the temperature, the faster the particles are moving and the more thermal energy they possess.
3. How is thermal energy transferred?
Thermal energy can be transferred through conduction, convection, and radiation. Conduction is the direct transfer of heat between two objects in contact. Convection is the transfer of thermal energy through the movement of particles in a fluid or gas. Radiation is the transfer of thermal energy through the emission of electromagnetic radiation, such as sunlight.
