Fussion: means combine 2 light nucleus to form heavier nucleus.
Fission: means splitting heavy nucleus to form lighter nucleus.

Answer:
New pressure (P2) = 22.92 Kpa (Approx)
Explanation:
Given:
Old pressure (P1) = 22 Kpa
Temperature (T1) = 287 K
Temperature (T2) = 299 K
Find:
New pressure (P2)
Computation:
P1 / T1 = P2 / T2
22 / 287 = P2 / 299
New pressure (P2) = 22.92 Kpa (Approx)
I think it might be a gravitational pull
