1) The initial volume of a balloon is 0.50 L. The initial temperature of the balloon is 150K. The volume in the balloon increased to 1.00 L. What is the final temperature?

Use the below equation. Round to the nearest whole number and do not use units in your final answer.

T2=V2 x T1V1

2) A 2.5L container of an unknown gas has a pressure of 300kPa. The container is squeezed and has a final volume of 2.0L.

What is the final pressure of the container?
Use the below equation. Round to the nearest whole number and do not use units.

P2 =P1V1/V2

3) Charles’ law is
V1T1=V2T2
A closed container has an initial temperature of 300K. The container volume is changed until the final volume is 2L and the final temperature is 425K.

Calculate the initial volume using the equation from Charles' Law.

Use 2 decimal points in your answer and do not use units.
