Aweather balloon slowly expands as energy is transferred as heat from the outside air. if the average net pressure is 1.5×10^5m^3, how much work is done by the expanding gas?

W =

Explanation:

The rest of the question actually states that:

**If the average net pressure is 1.5x10^3Pa and the balloons volume increases by 5.4x10^-5 m^3, how much work is done by the expanding gas.**

Work done, W against an external pressure, , which causes a change in volume, ΔV of an object is given as:

ΔV

=

ΔV =

=>  

Note: The negative sign denotes that the work is done against external pressure.

another example of kinetic energy would be,

kinetic energy   >     moving energy
