Water vapour is a gas. Gases change state when they cool. A volume of 2.5 × 10^–5 m3 of condensation forms on a bathroom mirror.
Density of water = 1000 kg / m3
Specific latent heat of vaporisation of water = 2.26 × 10^6 J / kg.
Calculate the energy released when the condensation forms.

E =m L

Suppose you use a machine that gives you a mechanical advantage of 2 to achieve an output force of 30newtons what must the input force be

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
