Ch 7- gas laws Flashcards
1
Q
Charles law
A
As volume increase, temp increases at constant pressure
2
Q
If given volume and temp only whats the formula….
A
v1/t1 = v2/t2
*VOT
3
Q

A
p1/t1 = p2/t2
*POT
5
Q
Boyles law
A
As volume decreases, pressure increases
6
Q

A
P1V1=P2V2
*pvvvv
7
Q
If given pressure and volume and temp whats the formula…
A
V1P1/T1 = V2P2/T2
8
Q
Avogadros law
A
volume of gas at constant temp and pressure is proportional to # of mols
9
Q
What are the ideal gas laws?
A
- they don’t take up space
- they don’t interact with each other
10
Q
how to convert pressure
A
1 atm = 760 mmHg = 101.3 kpa
11
Q
ideal gas laws formula
A
pv=nrt
12
Q
How to find how much gas moves?
A
va/vb = √mb/ma
v=speed, m= molar mass
