Answer 9

The change of a substance from a gas to a liquid

Question 10

Crystalline solid

Answer 10

Crystalline solids have and orders arrangement of atoms or molecules

Question 11

Amorphous solid

Answer 11

Amorphous solids are composed 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 cause a liquid to form spherical drops

Question 13

Kinetic energy

Answer 13

Energy of motion

Question 14

Heat

Answer 14

A transfer of energy that causes the temperature of a substance to change, which can lead to a change of state

Question 15

Endothermic change

Answer 15

Changes that require energy

Question 16

Exothermic change

Answer 16

Changes that release energy

Question 17

Fluid

Answer 17

A nonsolid state of matter in which the atoms or molecules are free to move past each other as in a gas or liquid

Question 18

Buoyant force

Answer 18

The upward force exerted on an object immersed in or floating on a fluid

Question 19

Pressure

Answer 19

The amount of force exerted per unit of a surface

Question 20

Archimedes’ principle

Answer 20

The principle that states that the buoyant force on an object in a fluid is an upward force equal to the weight of the volume of fluid that the object displaces

Question 21

Pascal

Answer 21

The SI unit of pressure - equal to the force of 1 N exerted over an area of 1 M^2
(abbv. Pa)

Question 22

Pascal’s principle

Answer 22

The principle that states that a fluid in equilibrium contained in a vessel exerts a pressure of equal intensity in all directions

Question 23

Viscosity

Answer 23

The resistance of a gas or liquid to flow

Question 24

Boyle’s law

Answer 24

The law that states that for a fixed amount of gas at a constant temperature, the volumes of the gas increases as the pressure of the gas decreases and the volume of the gas increases

Question 25

Charles's law

Answer 25

The law that states that for a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperature of the gas increases and the volume of the gas decreases as the temperature of the gas decreases

Question 26

Gay-Lussac's law

Answer 26

The law that states that the pressure of a gas at a constant volume is directly proportional to the absolute temperature
