Answer 1

fluid is any substance that can flow normally liquids or gas

Question 2

what is liquid

Answer 2

liquid is and fluid that can take a shape

Question 3

what is gas

Answer 3

a type of fluid that has no definite shape

Question 4

what is pressure

Answer 4

pressure is force applied over area

Question 5

what is atmospheric pressure

Answer 5

the pressure of the air and the elevation

Question 6

what is elevation

Answer 6

elevation is the higher you get above sea level

Question 7

what is density

Answer 7

a measure of how tightly packed an object is

Question 8

what is buoyant force

Answer 8

buoyant force is the force keeping things floating and causes displacement

Question 9

what causes pressure to increase

Answer 9

area decrease

Question 10

what causes pressure to decrease

Answer 10

area increase

Question 11

does the pressure of fluid increase of decrease with depth

Answer 11

increase with depth

Question 12

what is under water pressure

Answer 12

the pressure of air and water on you

Question 13

archimedes principle states…

Answer 13

that a buoyant force on an object is equal to the weight of the displaced fluid

Question 14

the grater the ___ an object has the more it weighs

Answer 14

mass

Question 15

what causes an object to float

Answer 15

the buoyancy and if the weight equals the buoyant fore or not, and volume the larger equals more buoyancy and more displaced fluids

Question 16

what causes objects to sink

Answer 16

the more mass and the lack of buoyancy

Question 17

how does a balloon float

Answer 17

if the force of gravity on the balloon is weaker than the buoyant force, low density paired with large amounts of greater density and the gas(helium)and greater volume.
