Question

T=PV/k, determined P when T=80, V=20 and K= 0.5

Answer 1

We have the following equation:

$T=\frac{PV}{k}$

since we need P, we must move k and V to the left hand side as

$P=\frac{k\cdot T}{V}$

By substituting the given values, we get

$\begin{gathered} P=\frac{(0.5)(80)}{20} \\ P=\frac{40}{20} \\ P=2 \end{gathered}$

that is, P is equal to 2.
