Question

1. The volume of a gas in a flexible container is 1.25 L at 5°C. What is the volume of the gas when it is heated to 75°C? Assume the pressure of the gas remains constant throughout the process. Be sure to include dimensional analysis and consideration of significant figures in your work. Also explicitly show any algebraic steps you use. 2. A 15.00 g sample of helium gas is placed in a 2.50 L flask at 25°C. What is the pressure of the helium? Be sure to include dimensional analysis and consideration of significant figures in your work. Also explicitly show any algebraic steps you use. -1. :a filled with a gas to a

Explanation / Answer

1)

we have:

V1 = 1.25 L

T1 = 5.0 oC

= (5.0+273) K

= 278 K

T2 = 75.0 oC

= (75.0+273) K

= 348 K

we have below equation to be used:

V1/T1 = V2/T2

1.25 L / 278.0 K = V2 / 348.0 K

V2 = 1.56 L

Answer: 1.56 L
