Question

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.

Answer 1

The undersigned only for use your own email and delete any and copies and of the itself and to be there is a good time what does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the molecules decreased kinetic energy of the molecules increased chemical energy of the molecules increased kinetic energy of the molecule show does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
