Question

In the mathematical equation showing that volume (V) divided by temperature (T) remains equal to a constant (k), volume and temperature are _______________ proportional

Answer 1

Directly

Step-by-step explanation:

`(V)/(T) = k`

If V increases, then T must also increase to keep the same ratio.

If V decreases, then T must also decrease to keep the same ratio.

V and T are directly proportional, because a change in one always causes a change in the other and the changes are in the same ratio. The constant k is called the proportionality constant.
