transfer of thermal energy by collisions between the particles that make up matter

transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from one place to another

states that a change in the internal energy of a system is equal to the change in the thermal energy plus the work done by the system

thermal energy that flows from a warmer material to a cooler material

device that converts some thermal energy into mechanical energy

transfer of energy by electromagnetic waves

heat engine that burns fuel inside the engine in chambers or cylinders

states that thermal energy will only flow from a cool object to a warmer object when work is done

device used in an active solar heating system that absorbs radiant energy from the Sun
