A gas system has initial volume and temperature of 7.07 L and 24.8 C. If the temperature changes to 230.0 K, what will the new volume be in mL?

Answer 1

Given:

V1 = 7.07 L

T1 = 24.8ºC + 273 = 297.8K (note: always use Kelvin (K) when working with gases)

T2 = 230.0K

Asked for:

V2 in ml

Use V1/T1 = V2/T2 (Charle's Law) and solve for V2 in L and then convert to mls.

V2 = V1T2/T1

Plug in the above values and solve. The answer will be in L so multiply by 1000 to get mls.
