Answer:
Gjvb
Explanation:
Using the combined gas law equation as follows:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (kPa)
P2 = final pressure (kPa)
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to this question;
T1 = 300K
T2 = -73 + 273 = 200K
P1 = 303kPa
P2 = 202kPa
V1 = 2L
V2 = ?
Using the above formula:
303 × 2/300 = 202 × V2/200
606/300 = 202V2/200
Cross multiply;
606 × 200 = 300 × 202V2
121200 = 60600V2
V2 = 121200/60600
V2 = 2L
The new volume is 2L
