Heat
* Definition: Heat is the transfer of thermal energy between objects at different temperatures. It's a measure of the internal energy of a system.
* Units: Measured in Joules (J) or calories (cal).
Conduction
* Definition: Conduction is one of the three main ways heat can be transferred. It occurs when heat moves through a material from a warmer to a cooler region by direct contact between molecules.
* Example: Holding a hot cup of coffee, your hand gets warm because heat is conducted from the cup to your hand.
In short: Heat is the energy itself, and conduction is one way that heat can travel.
Here's an analogy:
Imagine heat is like water flowing through a pipe. The water is the heat energy. Conduction is like a pipe that allows the water to flow from a higher point to a lower point.
There are two other main ways heat can be transferred:
* Convection: Heat transfer through the movement of fluids (liquids and gases). Think of boiling water on the stove, the hot water rises and colder water sinks, creating a convection current.
* Radiation: Heat transfer through electromagnetic waves. Think of the sun warming the Earth.
