KSEEB Solutions for Class 8 Science – Questions & Answers for Easy Learning

Sample Questions and Answers:

Physics:

What is force?
Force is a push or pull applied to an object that can change its state of motion or shape. It is measured in Newtons (N).

What are the different types of forces?
The main types of forces are contact forces (like friction and tension) and non-contact forces (like gravitational and magnetic force).

What is friction?
Friction is a force that opposes the motion of objects when they come in contact with each other. It can be useful (like in walking) or unwanted (like in machine wear and tear).

Why do objects fall to the ground?
Objects fall to the ground due to the force of gravity, which pulls them toward the center of the Earth.

How does a simple machine make work easier?
Simple machines like levers and pulleys reduce the effort needed to perform tasks by increasing force or changing its direction.

What is pressure?
Pressure is the force applied per unit area. It is calculated using the formula Pressure = Force / Area and is measured in Pascals (Pa).

Why do deep-sea divers wear special suits?
Deep-sea divers wear special suits to withstand high water pressure and prevent harm to their bodies at great depths.

What is the difference between mass and weight?
Mass is the amount of matter in an object and remains constant, whereas weight is the force of gravity acting on mass and can vary with location.

Why do astronauts float in space?
Astronauts float in space because they are in a state of free fall around the Earth, experiencing weightlessness.

How does heat transfer take place?
Heat transfer occurs through conduction (direct contact), convection (movement of fluids), and radiation (electromagnetic waves).

Why does metal feel colder than wood at the same temperature?
Metal conducts heat away from your skin faster than wood, making it feel colder even though both are at the same temperature.

What is the principle of conservation of energy?
The principle states that energy can neither be created nor destroyed; it can only be transformed from one form to another.

Why do we see lightning before we hear thunder?
Light travels faster than sound, so we see the lightning before hearing the thunder, even though both happen simultaneously.

How does a thermometer work?
A thermometer works by using the expansion and contraction of a liquid (like mercury or alcohol) to measure temperature changes.

What is the difference between reflection and refraction?
Reflection is the bouncing back of light from a surface, while refraction is the bending of light as it passes through different mediums.

What causes a rainbow?
A rainbow is formed when sunlight is refracted, reflected, and dispersed by water droplets in the air, breaking white light into its seven colors.

What is sound?
Sound is a form of energy that travels in waves through a medium like air, water, or solids.

Why does sound travel faster in solids than in gases?
Sound travels faster in solids because particles in solids are closely packed, allowing vibrations to transfer more quickly.

What is an echo?
An echo is the reflection of sound waves from a surface that is heard after a delay.

How does a magnet attract iron?
Magnets produce a magnetic field that exerts force on iron and other magnetic materials, pulling them toward the magnet.

Chemistry:

What is matter?
Matter is anything that has mass and occupies space. It exists in three states: solid, liquid, and gas.

What is the difference between an element and a compound?
An element is a pure substance consisting of one type of atom, whereas a compound is a substance formed by the chemical combination of two or more elements.

Why do liquids take the shape of their container?
Liquids have a definite volume but no fixed shape, so they take the shape of the container they are placed in.

What is evaporation?
Evaporation is the process where a liquid turns into a gas at temperatures below its boiling point, often due to heat absorption.

What happens when sugar dissolves in water?
When sugar dissolves in water, it spreads evenly, forming a homogeneous solution without changing chemically.

What is rusting?
Rusting is a slow chemical reaction where iron reacts with oxygen and water to form iron oxide, commonly known as rust.

What is an acid?
An acid is a substance that releases hydrogen ions in a solution, tastes sour, and turns blue litmus paper red.

What is a base?
A base is a substance that releases hydroxide ions in a solution, tastes bitter, and turns red litmus paper blue.

Why does salt dissolve in water but not in oil?
Salt dissolves in water because water molecules are polar and can separate salt ions, whereas oil is non-polar and does not interact with salt.

What are synthetic fibers?
Synthetic fibers are man-made fibers like nylon and polyester, created from chemicals instead of natural sources like cotton or wool.

Why is plastic harmful to the environment?
Plastic does not decompose easily, leading to pollution and harm to wildlife and ecosystems.

What is the difference between physical and chemical changes?
A physical change alters the form of a substance without changing its composition, while a chemical change results in the formation of new substances.

What are noble gases?
Noble gases are elements like helium, neon, and argon that are inert and do not easily react with other elements.

What is the importance of water purification?
Water purification removes harmful substances and microorganisms, making water safe for drinking and use.

What is a catalyst?
A catalyst is a substance that speeds up a chemical reaction without being consumed in the process.

Why do metals conduct electricity?
Metals have free-moving electrons that allow electricity to pass through them easily.

What are biodegradable and non-biodegradable substances?
Biodegradable substances break down naturally (like paper and food waste), while non-biodegradable substances (like plastic) do not decompose easily.

What is an alloy?
An alloy is a mixture of two or more metals to improve strength and durability, such as steel or bronze.

Why do some metals corrode?
Metals corrode when they react with moisture and oxygen, forming compounds like rust.

What is chromatography?
Chromatography is a method used to separate and analyze different components of a mixture based on their movement through a medium.
