Q

What does the pressure of a gas depend on?

A

mass of molecules

speed of molecules - hitting walls more often

how many molecules - more molecules to hit the walls

17
Q

What happens when the volume of a gas decreases while the temperature stays the same?

A

The average speed stays the same but the molecules hit the walls more often

18
Q

What does Boyles law state?

A

The pressure of a fixed mass of gas at a constant temperature is inversely proportional to its volume

pV=constant

19
Q

pV=constant or…

A

p1V1=p2V2

20
Q

Why are things different densities?

A

some atoms might have more mass than others

some atoms may be smaller so more can fit in the same space

they might be arranged differently

21
Q

Equation for mass?

A

Density x volume

22
Q

Equation for distance?

A

Distance = speed x time

23
Q

Equation for force?

A

Force = pressure x area

24
Q

Equation for area?

A

Area = force / pressure

25
Q

Reasons for a difference in mass of the same volume?

A
  • some atoms may have more mass than others
  • some atoms may be smaller so more can fit
  • some atoms may be arranged different so more can fit
