Final answer:
The formula for P in terms of V is P = 40/V.
Step-by-step explanation:
The relationship between pressure (P) and volume (V) is inversely proportional, which means as the volume increases, the pressure decreases, and vice versa. Mathematically, this can be represented as P.V = k, where k is a constant. To find a formula for P in terms of V, we can rearrange the equation to solve for P: P = k/V.
Given that V=8 and P=5, we can substitute these values into the equation to find the value of k: 5 = k/8, k = 40.
Now we can substitute the value of k back into the formula: P = 40/V.
