Juice
Matter is defined as what
Anything that takes up space and has mass
How is weight different to mass

Decrease pressure
What do you use to measure atmospheric pressure
A barometer
What does a barometer use for accurate readings
A vernier scale
Atmospheric pressure is not affected by the humidity of the air
T or F
False
What direction is fluid pressure exerted
In all directions
Define force
A simple push, pull, or weight exerted over the entire area

What would the boiling point be for water at the top of mt everest
Less than 212 F
A column of water 1’ high exerts what pressure
0.433 lb/in2
What does Boyles law state
Pressure increases volume decreases
What is conduction
Heat occurs when a warmer object is touching a cooler object
What is convection
Less dense warmer areas of water and gas rise to a cooler area
What is radiation
Uses electromagnetic waves to transfer heat
What is sensible heat
Energy is transferred as heat to an object, changing its temperature but not it’s state
What is latent heat
Energy released or absorbed that changes the state of a body during a constant temperature process
How do you calculate bouyent force
Volume x density
