Answer 1

Answer #1

W= work is a energy applied to move a object or other against a force.

energy- energy is a system can change due to work applied on a object. then we can say another form of energy is heat transfer one to another object

we know from gases theory

W = -P $\Delta$ V......................(1)

$\Delta$ V is change of volume

$\Delta$ = V_final - V_Initial

correct expression-- $\Delta W$ =F. $\Delta$ X F =P/A

W = P.A $\Delta X$ $\Delta$ X=displacement

02 W = P.A.A.C

=P(V₂ - V₁)

W = PAV
