Answer 10

Liquid

Question 11

The temperature at which the motion of atoms particles and electrons stops

Answer 11

Absolute zero

Question 12

State of matter that has an indefinite volume indefinite shape and particles spread apart dorm each other quickly

Answer 12

Gas

Question 13

State of matter with particles close together, moving in fixed positions hold it’s own shape

Answer 13

Solid

Question 14

The buoyant force on an object in a fluid is equal to the weight of the fluid displaced by the object explains why an object will sink or float

Answer 14

Archimedes principle

Question 15

The faster a fluid flows the less pressure the slower a fluid flows the graters the pressure explains why airplanes fly

Answer 15

Bernoulli principle

Question 16

This equals force divided by area

Answer 16
