Which arrow represents the change of state described above?
The diagram shows changes of state between solid,
liquid, and gas. The atoms of a substance gain energy
during a change of state. Before the change, the
atoms are close together and cannot slide past one
another. After the change, the substance can fill its
container
gas

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
