states of matter Haleigh Miller

Question 0

Liquid

Answer 0

Closely packed but can slide past eachother.

Question 1

Solid

Answer 1

Have a definite shape and volume , in fixed positions.

Question 2

Gas

Answer 2

Are in a constant state of motion and rarely stick together.

Question 3

Plasma

Answer 3

A state of matter that starts as a gas and then becomes ionized

Question 4

Energy

Answer 4

The capacity to do work

Question 5

Thermal energy

Answer 5

This kinetic energy of a substances atoms

Question 6

Evaporation

Answer 6

The change of a substance from a liquid to a gas

Question 7

Sublimation

Answer 7

The process in which a solid changes directly into a gas

Question 8

Condensation

Answer 8

The change of a substance from a gas to a liquid

Question 9

Crystalline solid

Answer 9

Have an orderly arrangement of atoms or molecules example iron, diamond, ice

Question 10

Amorphous solid

Answer 10

Are composed of atoms or molecules that are in no particular order

Question 11

Surface tension

Answer 11

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

Question 12

Kinetic energy

Answer 12

Particles are in motion or energy of motion

Question 13

Heat

Answer 13

A transfer of energy known as heat causes the temp of a substance to change which can lead to a change of state

Question 14

Endothermic change

Answer 14

When melts it requires endothermic energy makes the molecule move faster to melt the solid

Question 15

Exothermic change

Answer 15

Like condensation freezing is an exothermic change because energy is released from the substances as it changes state. Motion of the particles slow down

Question 16

Fluid

Answer 16

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

Question 17

Buoyant force

Answer 17

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

Question 18

Pressure

Answer 18

The amount of force exerted per unit area of a surface

Question 19

Archimedes Principle

Answer 19

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 20

Pascal

Answer 20

The SI unit of pressure

Question 21

Pascals Principle

Answer 21

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

Question 22

Viscosity

Answer 22

The resistance of a gas or liquid to flow

Question 23

Bernoulli’s Principle

Answer 23

Fluid pressure decreases as the speed of moving fluid increases

Question 24

Boyle’s Law

Answer 24

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

Question 25

Charles 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- Lussacs law

Answer 26

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