⁠
Answer in one line
Name the three states in which water can exist.
Water can exist in three states: solid, liquid, and gas.
What common property do all three forms of water share regarding space?
All three forms of water (solid, liquid, and gas) occupy space.
What is the characteristic of solid water (ice) regarding its shape and size?
Solid water, known as ice, has a fixed shape and a fixed size.
List two common daily uses of liquid water.
Two common daily uses of liquid water are drinking and washing.
Define the process of evaporation.
Evaporation is the process in which a liquid changes into vapours (gaseous state) when heated.
Explain how water droplets form on the surface of a cold glass.
Water droplets form on a cold glass surface because water vapour in the atmosphere condenses into liquid when it comes into contact with the cool surface.
What is solidification?
Solidification is the process in which a liquid changes into a solid, typically when exposed to freezing temperatures.
Define sublimation.
Sublimation is the process where a solid changes directly into a gas without first passing through the liquid phase.
Define deposition.
Deposition is the process where a gas changes directly into a solid without first passing through the liquid phase.
What is a solute in the context of a solution?
A solute is the substance that dissolves in a solvent to form a solution.
Why is water referred to as the “universal solvent”?
Water is referred to as the “universal solvent” because it has the ability to dissolve most substances.
List one condition that speeds up the formation of a solution.
One condition that speeds up the formation of a solution is heating the solvent.
How does increasing the quantity of a solvent affect the speed of solution formation?
Increasing the quantity of a solvent can make the solution form faster.
What is an insoluble substance?
An insoluble substance is a material that does not dissolve in a solvent to form a solution.
Is it true that bigger objects always sink and smaller objects always float in water? Explain briefly.
No, it is not true; whether an object sinks or floats depends on the amount of water it displaces relative to its own weight, not just its size.
According to Archimedes’ principle, when will an object sink in water?
According to Archimedes’ principle, an object will sink in water if it displaces less water than its own weight.
What did Archimedes explain about objects in water?
Archimedes was the first to explain why some things float and some things sink in water.
