I've read books saying that heat and thermal energy are the same and I've read other books saying they are not the same. I'm confused now. Which of them is right? or maybe they're both right?
Heat is a form of energy that is transferred from a warmer object to a cooler object, while thermal energy is the total internal energy of an object due to the motion of its particles.
Heat can be transferred through three main mechanisms: conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between two objects, convection is the transfer of heat through the movement of fluids, and radiation is the transfer of heat through electromagnetic waves.
The unit of measurement for heat and thermal energy is joules (J) in the International System of Units (SI).
The higher the amount of thermal energy, the faster the particles will move and the more they will spread out. This can lead to changes in state (solid, liquid, gas) and can also affect the chemical reactions and physical properties of substances.
The sun produces heat and thermal energy through nuclear fusion, where hydrogen atoms combine to form helium, releasing a large amount of energy in the process. This energy is then radiated out as heat and light, which is what we feel and see from the sun.
