If k is a constant, how will a change in volume change the pressure?

Question

Choose one set of numbers. Assign one of them to represent P and the other to represent V. What happens to P if V is assigned the larger number? What happens to P if V is assigned the lower number?

Observe the relationship between P and V. Is it a directly proportional relationship or an inversely proportional relationship?

Answer 1

The first two lines ask a question. If P goes up, V goes down.

I don't know what you want for the rest of the post.

Answer 2

Does the graph show a proportional relationship? Explain.
