Answer:The total energy of all particles in an object is known as thermal energy. Thermal energy refers to the sum of the kinetic energy and potential energy of the particles in an object. Kinetic energy is the energy associated with the movement of particles, while potential energy is the energy associated with the position or arrangement of particles. When particles in an object move faster, their kinetic energy increases, leading to an increase in thermal energy. Similarly, when the particles are closer together or in a more compact arrangement, their potential energy increases, contributing to the overall thermal energy. For example, consider a cup of hot coffee. The coffee contains particles (molecules) that are constantly moving and colliding with each other. The faster these particles move, the higher their kinetic energy and the higher the thermal energy of the coffee. This is why the coffee feels hot to touch. Other options provided in the question, such as temperature, electromagnetic energy, and chemical energy, are not the correct answers. Temperature is a measure of the average kinetic energy of particles in an object, but it does not represent the total energy of all particles. Electromagnetic energy refers to the energy associated with electromagnetic waves, such as light or radio waves, and is not directly related to the energy of particles in an object. Chemical energy refers to the potential energy stored in the bonds between atoms in a molecule and is not necessarily representative of the total energy of all particles in an object.
