Answer: Option B) direct
Explanation:
The pressure (p) of a fixed mass of gas is always in direct proportion to the absolute temperature (T) while its volume (v) remains constant. This is a statement of the pressure law, and it can be mathematically expressed as:
P ∝ T
P = kT (where k is a constant)
Thus, k = P/T
While for different conditions, it becomes
(P1/T1 = P2/T2)
Thus, there is a direct type of relationship between pressure and temperature.
