Why does water feel cool when it evaporates

Physics

Basically, when water evaporates, it always absorbs energy. What happens is that a molecule steals surface energy for all molecules until it is hot enough to evaporate. This is how the evaporation process happens. For this reason, the surface cools because the molecules steal the heat from the medium. This can easily be noticed when we sweat and after the water molecules evaporate from our body, it cools.

A 6157 N piano is to be pushed up a(n) 2.41 m frictionless plank that makes an angle of 21.9 ◦ with the horizontal. Calculate th
xz_007 [3.2K]

Answer:

Work done, W = 5534.53 J

Explanation:

It is given that,

Force acting on the piano, F = 6157 N

It is pushed up a distance of 2.41 m friction less plank.

Let W is the work done in sliding the piano up the plank at a slow constant rate. It is given by :

W=Fd\ sin\theta

Since, F=F\ sin\theta (in vertical direction)

W=6157\times 2.41\ sin(21.9)

W = 5534.53 J

So, the work done in sliding the piano up the plank is 5534.53 J. Hence, this is the required solution.

Can you change the weight of something without changing the mass?
svlad2 [7]

yes because your mass doesn't change but your weight can


ex- if you travel to Saturn your weight would change but your mass would stay the same
