Answer:
The final temperature is 800KPa
Explanation:
The following were obtained from the question:
P1 = 200 kPa
T1 = 100 K
T2 = 400 K
P2 =?
Since the tank is rigid, the volume of the tank is constant.
Using P1/T1 = P2/T2, we can obtain the new pressure as illustrated below:
200/100 = P2 /400
Cross multiply to express in linear form:
100 x P2 = 200 x 400
Divide both side by 100
P2 = (200 x 400) /100
P2 = 800KPa
The final temperature is 800KPa
