Step-by-step explanation:
A boat floats on water because it is less dense than the water it displaces. The boat is shaped in such a way that the weight of the boat is spread over a large surface area, which helps it float. A stone, on the other hand, sinks into water because it is more dense than water and does not displace enough water to support its weight.

Three factors that can affect rate of dissolving are:
Temperature: higher temperatures usually result in faster dissolving rates as the molecules move more quickly and have more energy to break apart.
Stirring/agitation: stirring or agitating a solution helps to distribute the solute particles more evenly throughout the solvent, which can increase the rate of dissolving.
Particle size: smaller particles of solute will dissolve faster than larger particles as they have a larger surface area available for interaction with the solvent.
The air we breathe in travels into our cells as follows: Nose/mouth --> trachea --> bronchi --> bronchioles --> alveoli --> bloodstream --> cells.
The main function of the brain is to control and coordinate bodily functions, including movement, sensation, thought, and emotion. The main function of the kidneys is to filter waste products and excess fluid from the blood, and to maintain a balance of electrolytes and other substances in the body.
