Question

A gas occupies 475 cm^3 at 313K. Find its volume at 367K. You must show all of your work to receive credit. Be sure to identify which of the Gas Laws you will be using

Answer 1

We are given volumes and temperatures so we use Charles' Law.

V1 / T1 = V2/T2

So we have the equation:

475/ 313 = V2 / 367 (where V2 is the volume required).

V2 = 475 * 367 / 313

= 557 cm^3 to the nearest cm^3 (answer) .

Answer 2

gas pressure is not specified. assume its constant, we can use charles law which states w/ constant press. gas vol is directly proportional 2 its temp.

so V1/T1=V2/T2

V2=T2*V1/T1

=367*475/313

=556.94888cm^3

=556.95cm^3
