Heat and Temperature
Kinetic and Potential energy
Kinetic Energy is energy that is moving.
Example: A roller coaster going down the tracks at a drop.
Potential energy is energy that is stored.
Example: A roller coaster that stops on the tracks at the stop of a drop.
Physical Arrangements in Solids, Liquids, and Gases
In solids, the particles move very slowly and tightly packed together. Liquids' partials are spread apart and moving slightly faster than solids. Gas particles are spread far apart and are moving very quickly.
Differences in Heat and Temperature
Heat is energy, but temperature is not. Temperature is the measure of heat, while heat depends on the size and mass of the particles of an object. Heat is the measure of thermal energy.
Different Forms of Heat Transfer
The different forms of heat transfer are known as conduction, convection, and radiation.
Conduction is when heat transfers between conductors such as metal through direct contact. The molecules vibrate very fast and rub against each other.
Example: Ice melting in your hand.
Radiation is when an object is heated through heat waves.
Example: Heat from a campfire.
Convection is heat transferring through currents of liquids or gases. The warmer areas of the liquid or gas rises to cooler areas.
Example: Boiling water in a pot.
