Question

The temperature of a sample of sulfur hexafluoride is changed, causing a change in volume from 376.6 mL to 1690.7 mL. If the starting temperature was 555.69 °C, what is the final temperature in degrees Celsius? which gas law did you use to solve this problem?



Answer 1

Given:

V1 = 376.6 ml

V2 = 1690.7 ml

T1 = 555.69ºC + 273 = 828.69K

Asked for:

T2 = ?

We must assume the pressure (P) is constant, and thus we will use Charles' Law V1/T1 = V2/T2

376.6 ml / 828.69 = 1690.7 ml / T2

T2 = 3720K - 273 = 3447ºC
