what law tells us that the volume of gas increases as the pressure decreases?
Answer: Boyles law
v1/T1=v2/T2
Charle's Law
What does P, V, and T stand for?
Pressure, Volume, Temperature
A gas occupies a volume of 5L and contains 4 moles. If the number of moles is reduced to 2 while keeping other conditions constant, what will be the new volume of the gas?
V2=2.5
Which gas law shows how moles and volume interact?
Advargo's Law
is the volume of a gas inversely proportional to its pressure and directly proportional to temperature and the amount of gas?
Answer: Yes
p1/T1=p2/T2
Gay - Lussac's Law
What does R stand for?
Ideal Gas Constant
A gas sample occupies a volume of 3 L and contains 0.5 moles. if the volume is increased to 6L while keeping other conditions constant, how many moles of gas are now present?
n2=1
What gas law is PV = nRT?
Ideal Gas Law
which of the 3 gas laws has an inverse relationship?
Answer: Boyles' law describes the inverse relationship between pressure and volume
p1xv1/T1=p2xv2/T2
Combined Gas Law
What does kPa stand for?
Kilopascals
a gas is initially at a pressure of 80 kPa, a volume of 3 L, and a temperature of 27c. if the volume is decreased to 2 L, and the temperature is increased to 127c, what will be the final pressure of the gas?
P2=160
What is the formula for Boye's Law?
