A

Nonsolid state of matter.

16
Q

What is a buoyant force?

A

The upward force on an object

17
Q

What is pressure?

A

The amount of force exert per unit

18
Q

What is Archimedes principle?

A

An principle that states the buoyant force on a object.

19
Q

What is a pascal?

A

The SI unit of pressure

20
Q

What is pascals principle?

A

The principle that states that a fluid in equilibrium.

21
Q

What is viscosity?

A

The resistance of a gas or liquid flow.

22
Q

What is Bernoulli’s principle?

A

States the speed of a moving object fluid increases the pressure of moving fluid decreases.

23
Q

What is endothermic change?

A

the word describes a process that releases energy in the form of heat. Forming a chemical bond releases energy and therefore is an exothermic process.

24
Q

What is Boyles law?

A

The absolute pressure exerted by a given mass

25
Q

What is charles law?

A

is an experimental gas law which describes how gases tend to expand when heated.

26
Q
