Answer:
For a confined, constant volume of gas, the ratio
P
T
is therefore constant (i.e.,
P
T
=
k
). If the gas is initially in “Condition 1” (with P = P1 and T = T1), and then changes to “Condition 2” (with P = P2 and T = T2), we have that
P
1
T
1
=
k
and
P
2
T
2
=
k
, which reduces to
P
1
T
1
=
P
2
T
2
