18 Questions
Which statement best describes the characteristics of solids?
Solids have a definite shape, distinct boundaries, and fixed volumes.
Why are solids considered rigid?
Because they tend to maintain their shape when subjected to outside force.
What differentiates a rubber band from typical solids?
A rubber band changes shape under force and regains the same shape later.
Why do sugar and salt take the shape of the jar they are kept in?
Because they are solids and adapt to the container's shape.
What is a characteristic of liquids according to the text?
Liquids have negligible compressibility.
Why do liquids flow easily from one container to another?
Because liquids do not have a definite shape.
What is a characteristic property of liquids based on the text?
Fixed volume
Which state of matter has particles that move freely with greater space between them compared to solids?
Liquid
Why is the rate of diffusion of liquids higher than that of solids?
Particles in liquids move freely
Why are oxygen and carbon dioxide essential for aquatic animals and plants?
For survival through respiration
How do aquatic animals breathe under water?
Through gills
What is the main reason that gases from the atmosphere can dissolve in water?
For survival of aquatic life
What is the term used to describe the intermixing of particles of two different types of matter on their own?
Diffusion
How does the kinetic energy of particles change with an increase in temperature?
Increases
What is observed just above the solid crystal when copper sulphate or potassium permanganate crystals are dropped into water?
Tiny bubbles rising from the crystals
What does the statement 'Particles of matter are continuously moving' suggest about particles?
Particles possess kinetic energy
What happens to diffusion when the temperature increases?
Diffusion speeds up
What can be concluded about the rate of mixing between liquids and solids?
Solids mix faster than liquids
Explore the properties of fluids, specifically liquids, including their ability to flow and take the shape of their container. Learn about the process of diffusion in liquids and how gases from the atmosphere dissolve in water, essential for the survival of aquatic animals and plants.
