gases

Question 1

two balloons are filled with helium. One is 2L, the other is 4L. Which balloon has faster moving molecules?

Answer 1

They will be moving at the same speed because the temperature, therefor the KE is the same.

Question 2

inversely proportional

Answer 2

if one goes up, the other goes down

PV

Question 3

partial pressures

Answer 3

dalton

Question 4

equal volumes contain equal particles

Answer 4

avogadro

Question 5

the pressure is inversely proportional to the volume

Answer 5

boyle

Question 6

the volume is directly proportional to the temperature

Answer 6

charles

Question 7

the volume of any gas at STP is

Answer 7

22.4L

Question 8

If the Kelvin temperature of 2L of a gas at STP doubles, the new volume would be

Answer 8

4L

Question 9

real gases act like ideal gases except at

Answer 9

very high pressures and very low temperatures

Question 10

the number of moles of a gas is ___ proportional to its volume at STP

Answer 10

directly

Question 11

directly proportional

Answer 11

as one goes down, the other does too.

Question 12

The ideal gas equation describes the behavior of gases as if there was no attraction between the gas molecules.
Why is this wrong?

Answer 12

The real gases have a lower limit to which molecles it can be compressed with. Real gas molecules do attract and repel molecules.

Question 13

Boyle’s law states that the pressure of a gas is inversely proportional to its

Answer 13

temperature

Question 14

if the pressure and temperature of a gas remain constant, the volume will increase if

Answer 14

the number of moles of the gas increases

Question 15

Which of these gases has the largest volume at STP?
A. 88g of CO2
B. 56g of nitrogen
C. 10g of helium
D. 64g of oxygen

Answer 15

C
