Explanation

• Wear and Tear is not an advantage of friction.
• It's a disadvantage, as friction causes wear and tear on surfaces.

Advantages of Friction:

• Walking: Friction between the soles of our shoes and the ground allows us to walk without slipping.
• Braking: Friction between the brake pads and the wheels allows vehicles to slow down and stop.
• Securing knots: Friction between the fibers of a rope helps keep knots tight and secure.
• Fasteners: Friction between threads in screws and bolts helps keep them in place and secure

Explanation

Friction is the force that generates heat and warmth when surfaces rub against each other.

Explanation

• Motion is the change in position of an object over time.
• When an object moves from one place to another, it is in motion.

Explanation

• Friction is a force that opposes motion between two surfaces that are in contact.
• It acts in the opposite direction of motion, making it harder to move an object or keep it moving.

Explanation

• Fog is a type of cloud that forms at ground level.
• It characterized by a thick cloud of water droplets suspended in the air near the Earth's surface.
• This reduces visibility and creates a misty or foggy condition.

Explanation

• Dew is a common outcome of condensation.
• Where water vapor in the air condenses onto surfaces.
• It forming tiny droplets of water.

Explanation

• When water evaporates, it changes from a liquid to a gas.
• This gaseous state is called water vapor.

Explanation

Melting is the process by which a solid (in this case, ice) changes to a liquid (water) when it is heated and gains energy.

Explanation

• Gases have neither a fixed volume nor a fixed shape.
• As their particles are widely spaced and free to move in any direction, expanding to fill their container.

Explanation

• Liquids have a fixed volume, but their shape changes depending on the container they are in.
• As their particles are close together but free to move past each other.
