Question

What is the internal energy in substances called?

Answer

Listen up class, the intrinsic energy in substances is known as internal energy, or U. This includes all the energy possessed by the particles that make up a substance, including kinetic energy from particle motion. The internal energy is closely tied to temperature, as an increase in temperature leads to an increase in kinetic energy and overall internal energy. Internal energy is made up of kinetic energy, electrical energy within atoms, and energy stored in bonds, and can be calculated using the formula ΔU = q + W, where U represents the change in internal energy, q is heat, and W is mechanical work.
