Question

the volume of gas at 27°c is 30ml what is the volume of gas at 37 degree celsius in constant pressure​

Answer 1

PV=nRT

V∝T

VT′=V′

T at constant pressure for a fixed amount of gas.

Initial volume V = 300 ml.

Initial temperature T = 27

C =27+273 K = 300 K

Final volume V' = ??.

Final temperature T' =− 8

C =273−8 K = 265 K.

300 mL× 265 K =V

′

× 300

V

′

= 265 ml

Hence, the final volume is 265 ml.
