What type of relationship exists between pressure and temperature? *
Is it
A inverse/indirect
B direct
C no relationship

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.
