from your variable,make a statement in the form of a hypothesis that your chosen factor has an effect on the number of water droplets a certain type of coin can hold.
HYPOTHESIS:______
Answers
A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it.
Answer:
17 Droplets
Explanation:
A coin contains lots of liquid molecules
The molecules stick together the force that jeeps them within close to each other. The force is called cohesive force.
Cohesion happens between all molecules in a liquid
Because the molecules in the middle of the droplet pull each other equally in all directions
The molecules at the surface of the droplet have air molecules above them instead of liquid molecules
This cause a cohesive bond between the molecules at the surface to be much stronger than those in the middle of the droplet
The strong inward force cause the molecules on the surface to contract and resist being streched or pulled apart creating an elastic tension at the liquid surface which is known as surface tension
