When particles collide with the surface of the solid.
C.
Water is polar because one side of the molecule is positive and the other is negative.
Explanation:
It happens because particles of gas are in constant random motion. Thus they can collide with the walls of the container causing pressure on the walls.
Density is calculated as mass divided by volume. If we are given an ice cube of side length 8.00 cm, then the volume of the cube is equivalent to (8.00 cm)^3 = 512 cm^3. Since we have a given mass of 476 g, we can divide:
476 g / 512 cm^3 = 0.930 g/cm^3
So the density of the sample of ice is 0.930 g/cm^3.
