What are the 3 properties of air?
What is mass,density,and pressure
100
The definition of Density
What is the amount of matter in a given space, or volume
100
if heat is added its molecules become?
What is less dense
200
The amount of mass in a given volume of air
What is density
200
If more mass is added to a set volume what happens to the density?
What is The density increases.
200
Can one object be hotter than another if they are at the same temperature?
What is One object might feel hotter, but that's only because it might conduct heat better than the other.
300
Why doesn't air pressure crush us?
What is the molecules in air push in all directions
300
Is density a physical or chemical property
What is physical property
300
what is tempature
What is the degree or intensity of heat present in a substance or object,
400
Distance above sea level.
What is altitude
400
How do you sink in a pool?
What is Let all the air out of your lungs so you become more dense.
400
if heat is removed from air,its molecules become wha less dense or more dense
What is more dense
500
When you have less pressure and density, what happens to the molecules in the air?
What is they spread further apart
500
If more mass is added to a set volume what happens to the density?
What is The density increases.
500
air molecules move from high to low pressure because?
What is the high pressure is cold and it becomes heavier as it decends to earths surface
