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

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

Afigure skater is rotating at a rate of 200 revolutions per minute. what is the angular speed, in units of rad/s? 20.9 12000 200 3.33

How do we measure or think of speed in the united states?
