Question

5) The volume of the gas at constant pressure is 360ml at 27oC

a) Calculate the temperature at which the volume of gas is reduced to 150ml at the

same pressure?

b) State the gas law associated to this law?​

Answer 1

Answer:

PV=nRT

V∝T

VT

T at constant pressure for a fixed amount of gas.

Initial volume V = 300 ml.

Initial temperature T = 27

o

C =27+273 K = 300 K

Final volume V' = ??.

Final temperature T' =− 8

o

C =273−8 K = 265 K.

300 mL× 265 K =V

× 300

V

= 265 ml

Hence, the final volume is 265 ml.
