The Can Experiment

 Hi everyone! Welcome to another post, today in science we did an experiment that relates to expansion and contraction. But before we did the experiment we first had to answer some questions.

a) What are expansion and contraction? why do they happen? 

Expansion is something that grows in size, while the contraction is when something has reduced in size. It happens when materials are subjected to heat or any other temperature.

b) Why did the can crinkle up?

When the hot water in the can was exposed to the ice-cold water the hot can's energy slowly disappears from the hot can. 

c) Were the water particles in the can speeding up or slowing doesn't as it was heated?

The water particles in the can were speeding up because the can was heating up, and because it was heating up it caused the particles or speed up. (Diffusion)

d) When the can got placed in the cold water, what happened to the particles inside the can? Why did it happen?

The water particles got slowed down and they then closely pack together.

e) If the can was put in cold water with the top opening pointing up, do you think the experiment would have still worked the same? why/why not?

I think that it would still work because we're still using hot and cold water, its just that the roles have reversed.
