Heat And Matter Vocab

Question 1

Atom

Answer 1

The smallest Particle of an element: made of electrons, protons, and neutrons.

Question 2

Energy Transfer

Answer 2

Movement of Energy from one system to another

Question 3

Heat

Answer 3

Energy is transferred between two objects of different temperatures that move continually in a predictable pattern, from a warmer site to a cooler site until all sites have reached temperature equilibrium.

Question 4

Kinetic Energy

Answer 4

Energy of Motion

Question 5

Matter

Answer 5

Anything that has volume and mass

Question 6

Molecule

Answer 6

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

Question 7

Potential energy

Answer 7

Energy that is stored in a system or object

Question 8

States of matter

Answer 8

Distinct forms of matter known in everyday experience: solid, liquid, and gas; also referred to as phases.

Question 9

Temperature

Answer 9

The average kinetic energy of all the particles in a material; measured by a thermometer in degrees (usually degrees Celsius or degrees Fahrenheit)

Question 10

Thermal Energy

Answer 10

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

Question 11

Total internal energy

Answer 11

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