Answer:
c
. slower and started moving in place.
Explanation:
Matter can exist generally in three phases, as a solid, liquid or gas. But it can be transformed from one phase to another by the removal or application of heat energy.
The water was initially in a liquid form in the sealed tank until energy was transferred out of the substance. Thus, this causes a change of state in which the water turns to a solid. Whereby during the process, the molecules of the water moved slowly until they are fixed at a point, and vibrates individually at their individual point.
Therefore the molecules of water moved slower and stated moving in place (i.e vibrating at a point). The water turns to an ice.
Answer:As an equation, the tangential velocity is the distance, 2π r, divided by the time, T. Thus, A point on the circle moves a distance 2π r in a time T. We can extend our equation by looking at a few ideas. These concepts include the angular speed, ω, and the frequency, f. The angular speed, ω, is a speed of rotation.
