Temperature

• Average kinetic energy of all the particles in a material; measured by a thermometer in degrees

• The total kinetic (motion) energy of the tiny particles that make up matter; the faster the particles move, the warmer the matter becomes

• The sum of all the kinetic energy (KE) and potential energy (PE) that is found within a substance

• Energy that is stored in a system or object

What is Thermal Energy (TE)

• Heat

• Average kinetic energy of all the particles in a material; measured by a thermometer in degrees

• The total kinetic (motion) energy of the tiny particles that make up matter; the faster the particles move, the warmer the matter becomes

• The simplest unit of a chemical compound that can exist, formed when two or more atoms join together chemically

Heat is defined as

• the transfer of thermal energy from one object to another due to temperature difference

• the temperature of a solid, liquid, or gas

• The kinetic energy of a solid, liquid, or gas.

You are doing your homework at a desk that is underneath a lamp. You start to feel hotter because of _?_ from the lamp.

• conduction
• convection
• radiation

What is Matter?

• Movement of energy from one system to another

• The simplest unit of a chemical compound that can exist, formed when two or more atoms join together chemically

• Energy of motion

• Anything that has volume and mass
