Question

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

Answer 1

We have the following equation:

`T=(PV)/(k)`

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

`P=(k\cdot T)/(V)`

By substituting the given values, we get

`\begin{gathered} P=((0.5)(80))/(20) \\ P=(40)/(20) \\ P=2 \end{gathered}`

that is, P is equal to 2.
