The molecules are jiggling faster. They have more energy of motion. We got a name for energy of motion. What do we call it . Kinetic energy. Kinetic energy. Theres more Kinetic Energy in the molecules in a hot cup of coffee than a you know that. Thats what it means to say that somethings hot, that it has more energy. We might say more thermal energy. More strictly speaking, well say more internal energy, more energy internal to the system. So theres much more internal energy in a hot cup of coffee than a cold cup of coffee. Whats got more internal energy, a hot cup of coffee or an iceberg floating down at the antarctica . Check your neighbor for an estimate. A humongous iceberg or a small hot cup of coffee which has the more internal energy . All the energy combined what would it be, gang . Yeah, the iceberg is frozen. How
