A sample of gas with a volume of 30.0 mL at 25.0^oC is heated to 50.0^oC. What is the new volume of the gas? Options: P1V1 = P2V2, P1/T1 + P2/T2, PV = nRT, V1/T1 = V2/T2

Back

V1/T1 = V2/T2

Front

If the pressure exerted by a gas at 298 K in a volume of 0.044 L is 3.81 atm, how many moles of gas are present? Options: P1/T1 = P2/T2, PV = nRT, V1/n1 = V2/n2, P1V1 = P2V2

Back

PV = nRT

A gas fills a balloon at a temperature of 27 ^oC and 1 atm of pressure. What will the pressure of the balloon be if the gas is heated to 127 ^oC? Options: P1V1 = P2V2, PV = nRT, P1/T1 = P2/T2, V1/T1 = V2/T2

Back

P1/T1 = P2/T2

Front

A 1.25 L volume of gas contains 4.5 moles. How many moles will be in 0.75 L?

Back

V1/n1 = V2/n2

Front

A student measures the pressure and volume of an empty water bottle to be 1.4 atm and 2.3 L. She then decreases the pressure to 0.65 atm. What is the new volume?

Back

5.0 L

Front

A student inflates a balloon with helium then places it in the freezer. What should the student expect?

Back
