Question

A gas cylinder contains 0.722 L of hydrogen gas at a pressure of 1074 kPa. If the gas is used to fill a balloon at a pressure of 97.2 kPa, what is the volume if the temperature of the gas remains constant?

Answer 1

Boyle’s law states that the volume of a fixed of gas varies inversely with the pressure at the constant temperature. Mathematically. Boyle’s law can be expressed as followed. PV=k P is the pressure, V is the volume, and k is a constant Since P and V vary inversely, there product remains the same. The inverse relationships between changes of pressure, and volume can be expressed as followed. P1v1=p1v1 P2 V2=v2p2 step 1 V2=(10.6 atm)•(0.722 m^3)/0.96 atm V=7.9721m^3

Answer 2

so its 506.66 L

Answer 3

explain to me how you got that answer?

Answer 4

did you do v=7.9721m^3 and calculate that?

Answer 5

7.9721 ^ 3 would make it 506.66, right?

Answer 6

yeah

Answer 7

correct so it would be 507 if you round it.

Answer 8

unless you need the decimal.

Answer 9

alright. Thank you.

Answer 10

your welcome 🙏.
