Density and buoyancy

Question 1

Whats Mass? Also is it constitant on your location or does it depenend on where you are

Answer 1

The ammount of matter in a object, consistant

Question 2

What is Mass mesured in?

Answer 2

Grams or Kg

Question 3

Whats weight?Also is it constitant on your location or does it depenend on where you are. And whats it measured in

Answer 3

Weight is depenedent on location, its the force of gravity acting on a object mesured in Newtons

Question 4

Formula for Volume

Answer 4

Volume=Length x Width x Height

Question 5

Whats volume?

Answer 5

Amount of space a object or substance takes up

Question 6

Unit in SOLID volume?

Answer 6

SOLID: cm^3 m^3

Question 7

Unit in LIQUID volume

Answer 7

L ( liters) or mL

Question 8

How do you measure volume of a irregular shape

Answer 8

Submerge in water, see how much water the object displaces

Question 9

Whats density?

Answer 9

Ammount of matter in a given volume of a substance

Question 10

Formula for density

Answer 10

D=M/V

Question 11

HOW IS DENSITY USEFULL FOR IDENTIFING OBJECTS?

Answer 11

ITS THE SAME FOR ALL SAMPLES OF A GIVEN SUBSTANCE

Question 12

IN THE FORMULA TRIANGLE THING WHATS ON TOP, BOTTOM LEFT THEN RIGHT

Answer 12

M (TOP) D (LEFT) V (RIGHT)

Question 13

FORMULA FOR VOLUME

Answer 13

M/D

Question 14

FORMULA FOR MASS

Answer 14

M=V X D

Question 15

Deffine Gravity

Answer 15

The natural force that causes an object to move toward the centre of the earth

Question 16

does mass depened on location

Answer 16

NO, MASS IS THE SAME. LIKE UR MASS IS THE SAME ON THE EARTH AS ON THE MOON

Question 17

does WEIGHT depened on location

Answer 17

NO, WEIGHT WOULD VARY, LIKE UR WEIGHT ON EARTH IS DIFFRENT THAN ON THE MOON

Question 18

WHATS A HYRDROMETER

Answer 18

AN INSTRUMENT DESIGNED TO MESURE LIQUID DENSITY

Question 19

WHATS VOLUME?

Answer 19

A MESUREMENT OF THE AMMOUNT OF SPACE OCCUPIED BY A SUBSTANCE

Question 20

DEFFINE FLOATING

Answer 20

A OBJECT REMAINS SUSPENDED IN A FLUID INSTEAD OF SINKING

Question 21

WHEN YOU GET IN A POOL, YOU _____________ AN AMMOUNT OF WATER EQUAL TO YOUR VOLUME

Answer 21

DISPLACE

Question 22

WHATS FORCE

Answer 22

A PUSH OR A PULL, ANYTHING THAT CAN CAUSE A CHANGE IN THE MOTION OF A OBJECT

Question 23

DEFFINE DENSITY

Answer 23

THE AMMOUNT OF MASSS IN A CERTAIN VOLUME OF A SUBSTANCE

Question 24

DEFFINITION OF BUOYANCY

Answer 24

THE UPWARD FORCE A FLUID EXERTS ON A OBJECT

Question 25

IF MORE WATER IS BEING DISPLACED, IS THAT A STRONGER BUOYANT FORCE?

Answer 25

YES

Question 26

IF THE VOLUME IS LESS THAN THE DENSITY, THIS ALLOWS A OBJECT TO FLOAT. TRUE OR FALSE

Answer 26

FALSE. VOLUME=DENSITY ALLOWS IT TO FLOAT

Question 27

FOR A OBJECT TO SINK, WHAT NEEDS TO BE THJE COMPARISON BETWEEN THE DENSITY OF THE FLUID AND THE DENSITY OF THE OBJECT

Answer 27

Dobject>Dfluid to sink

Question 27

FOR A OBJECT TO rise, WHAT NEEDS TO BE THJE COMPARISON BETWEEN THE DENSITY OF THE FLUID AND THE DENSITY OF THE OBJECT

Answer 27

Dobject

Question 27

FOR A OBJECT TO float, WHAT NEEDS TO BE THJE COMPARISON BETWEEN THE DENSITY OF THE FLUID AND THE DENSITY OF THE OBJECT

Answer 27

Dobject=Dfluid

Question 27

HOW DO AIRSHIP, BALLON, BLIMPS USE DENSITY AND BUOYANCY

Answer 27

THEY FILL BLIMP WITH HELIUM, HELIUM LESS DENCE THAN OXYGEN, MAKES IT FLOAT. OR THEY HEAT AIR, FORCE COLD AIR OUT, MAKING IT FLY, HOT AIR LESS DENSE THAN COLD

Question 28

Positive and negative of oil being less dense than water (it floats)

Answer 28

PRO: -EASY TO CLEAN CON: -HARD FOR AQUATIC ANIMAL TO BREATHE, BLOCKS SUNGLIGHT FROM GETTING IN WATER

Question 28

HOW DO SWIM ANIMALS AND SUBS USE BUOYANCY TO WORK

Answer 28

FORCE AIR OUT TO SINK, MORE WATER -> DOWN LESS -> UP
