Question

If I have 325 mL of oxygen gas at a temperature of 25°C,
and I heat it to a temperature of 75°C, what is the new
volume (in mL)?

Answer 1

Answer:

v2= 379.53 mL

Explanation:

use charles's law

v1\T1 = v2\T2

v1= 325mL

T1= 25 + 273= 298K         *temperature has to be in kelvins

T2= 75 + 273= 348K

v2=?

substitute;

325\298 = v2\348

v2= ( 348 x 325)\298

v2= 379.53 mL
