Answer 4

State of matter that starts as a gas and then becomes ionized. Most common state of matter.

Question 5

Energy

Answer 5

The capacity to do work.

Question 6

Thermal energy

Answer 6

The total kinetic energy of the particles that make up an object.

Question 7

Evaporation

Answer 7

When a substance changes from a liquid to a gas.

Question 8

Sublimation

Answer 8

Direct change of a solid to a gas.

Question 9

Condensation

Answer 9

When a gas changes into a liquid.

Question 10

Crystalline Solid

Answer 10

Have an orderly arrangement of atoms or molecules.

Question 11

Amorphous Solid

Answer 11

Made of atoms or molecules that are in no particular order.

Question 12

Surface Tension

Answer 12

The force acting on the particles at the surface of a liquid that cases spherical drops to form.

Question 13

Kinetic Energy

Answer 13

Energy of motion.

Question 14

Heat

Answer 14

Causes the temperature of a substance to change.

Question 15

Endothermic Change

Answer 15

Change that requires energy.

Question 16

Exothermic Change

Answer 16

Energy is released from the substance as it changes.

Question 17

Fluid

Answer 17

Has the ability to flow.

Question 18

Buoyant Force

Answer 18

The upward force that liquids exert on matter.

Question 19

Pressure

Answer 19

The amount of force exerted on a given area.

Question 20

Archimedes’ Principle

Answer 20

States that the buoyant force on an object in a fluid is an upward force equal to the weight of the fluid that the object displaces.

Question 21

Pascal

Answer 21

The SI unit for pressure.

Question 22

Pascal’s Principle

Answer 22

States that a change in pressure at any point in an enclosed fluid will be transmitted equally to all parts of the fluid.

Question 23

Viscosity

Answer 23

A liquid’s resistance to flow.

Question 24

Boyle’s Law

Answer 24

States that for a fixed amount of gas at a constant temperature, the volume of a gas increases as its pressure decreases.

Question 25

Charles’s Law

Answer 25

States that for a fixed amount of gas at a constant pressure the volume of the gas increases as its temperature increases.

Question 26

Gay-Lussac’s Law

Answer 26

States that the pressure of a gas increases as the temperature increases if the volume of the gas does not change.
