18 Questions
Why are gases highly compressible as compared to solids and liquids?
Gases have particles that are far apart with large spaces between them.
Which application demonstrates the use of compressed gas for household purposes?
Using liquefied petroleum gas (LPG) in cooking cylinders at home.
Why does the smell of food diffuse quickly in the air compared to solids and liquids?
The particles of gases move randomly at high speeds and spread faster.
What causes gases to exert pressure on the walls of a container?
The random movement and collisions of gas particles on the container walls.
In which state do gas particles move about randomly at high speed?
Gaseous state
Which property allows large volumes of a gas to be compressed into a small cylinder for easy transportation?
High compressibility of gases
Why are liquids considered fluid?
Because they take up the shape of the container they are in
Why do aquatic animals need dissolved oxygen in water?
To survive underwater
How does the rate of diffusion of liquids compare to that of solids?
Liquids diffuse faster than solids
What is the reason for the high rate of diffusion of liquids compared to solids?
Particles in liquids move freely with greater space between them
Why does a balloon seller use gas cylinders to fill balloons?
To fill a large number of balloons from one cylinder of gas
How does the random movement of gas particles contribute to their compressibility?
Gas particles move freely and occupy all available space
Why is water at room temperature considered a liquid?
It has a fixed volume and takes the shape of its container.
What property of an iron almirah makes it a solid at room temperature?
It maintains its shape and volume.
Why is ice at 273 K more effective in cooling than water at the same temperature?
Ice absorbs more heat to change into liquid form.
What produces more severe burns, boiling water or steam?
Steam, as it releases more heat when it condenses.
In the context of gas diffusion, what does the speed of gas diffusion depend on?
The mass of the gas particles.
In the model demonstrating movement of particles in solids, liquids, and gases, what is the main purpose of running fingers up and down the string rapidly?
To show rapid movement of gas particles.
