When you breathe on a cold window and it fogs up, that change of state is called: Condensation.
Condensation is: The process in which molecules of a gas slow down, come together, and form a liquid water that collects as droplets on a cold surface when humid air is in contact with it.
I know this because I learned it in science class in school.
Hope I helped!

Answer:
Explanation:
Since this is a distance v time graph, the slope of the line from 1s to 3s is the velocity. However, it looks like, at t=3, the velocity is 0, so getting the definite velocity is not going to happen. We can estimate it as closely as possible. Since the line is tending from the upper left to the lower right, the slope is negative, so the velocity is also negative. That leaves only C or D as our answers. And the slope is closer to -1 than to -5, so choice D. is the one you want.
Answer:
a) 
, b) 
Explanation:
a) The magnetic force experimented by a particle has the following vectorial form:
The charge of the electron is equal to 
. Then, cross product can be solved by using determinants:
The magnetic force is:
b) The charge of the proton is equal to 
. Then, cross product has the following determinant:
The magnetic force is:
It moves horizontally across the floor.
Lakes and rivers can be formed landforms from water
