States of matter Megan mayer

Question 0

What is a liquid?

Answer 0

They can change shape not volume. They have a definite volume but change shape depending on the object they are in

Question 1

What is a soild?

Answer 1

They have a definite shape and volume.

Question 2

What is a gas?

Answer 2

There molecules are free to spread in all directions.

Question 3

What is a plasma?

Answer 3

It’s a state of matter that does not have a define shape and the particles are broken apart. It starts out as a gas and then becomes ionized.

Question 4

What is energy?

Answer 4

The ability to change or move matter and to do work.

Question 5

What is thermal energy?

Answer 5

The total kinetic energy that make up an object. The molecules move faster when heated up.

Question 6

What is evaporation?

Answer 6

The change from a liquid to a gas.

Question 7

What is sublimation?

Answer 7

When a soild changes directly into a gas.

Question 8

What is condensation?

Answer 8

A change from gas to liquid.

Question 9

What is crystalline solid?

Answer 9

They are an arrangement of atoms or molecules in a order.

Question 10

What is a amorphous soild?

Answer 10

Atoms or molecules that are composed in no particular order.

Question 11

What is surface tension?

Answer 11

A force acting on particles that make the liquid to turn into spherical drops.

Question 12

What is kinetic energy?

Answer 12

The energy of motion.

Question 13

What is heat?

Answer 13

It causes the temperature of a substance change. Which can change the state of matter too.

Question 14

What is a endothermic change?

Answer 14

When a substance changes requiring melting and energy.

Question 15

What is a exoteric change?

Answer 15

When a substance is freezing and realizing energy while changes states of matter.

Question 16

What is a fluid?

Answer 16

A state of matter where the molecules are free to move past each other as Ina gas or a liquid.

Question 17

What is a buoyant force?

Answer 17

The upward force exerted on an object

Question 18

What is pressure?

Answer 18

The amount of force exerted per unit area of a surface

Question 19

What is the Archimedes’ principle?

Answer 19

The principle that states that the buoyant force on an object in a fluid is an upward force.

Question 20

What is pascal?

Answer 20

The SI unit for pressure. (Pa)

Question 21

What is pascal’s principle?

Answer 21

States that a fluid in equilibrium contained in a vessel exerts a pressure of equal intensity in all directions.

Question 22

What is viscosity?

Answer 22

The resistance of a gas or liquid to flow

Question 23

What is Bernoulli’s principle?

Answer 23

States that as speed of a moving fluid increases, the pressure of the moving fluid decreases.

Question 24

What is Boyle’s Law?

Answer 24

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

Question 25

What is Charles’s Law?

Answer 25

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

Question 26

What is Gay-Lusaac’s Law?

Answer 26

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