Explanation

• The solubility of a solute substance increases as the temperature of the solvent (liquid) increases.
• This is because heat energy helps to break the bonds between the solute particles and the solvent molecules, allowing more solute to dissolve.

Explanation

• Sublimation process is used for purifying a solid.
• Sublimation is the process where a solid changes directly into a gas without passing through the liquid state.

Explanation

Plants release more Carbon Dioxide (CO2) at night due to respiration.

Explanation

Weather satellites are used to provide weather forecasting and monitoring of weather patterns, climate change.

Explanation

• Plants don’t need shelter but they need air.
• Air provides the necessary carbon dioxide for photosynthesis and oxygen for respiration.

Explanation

• Meteoroids are small particles from space that enter the Earth's atmosphere.
• It producing a bright streak of light, commonly known as a shooting star or meteor.
• If a meteoroid survives its passage through the atmosphere and lands on Earth, it is called a meteorite.

Explanation

• If a celestial body moves around another large celestial body it is called a natural satellite.
• Natural satellites, like moons, orbit planets due to gravitational forces, distinguishing them from artificial satellites, asteroids, and planets.

Explanation

• The three bones in the middle ear are the malleus (hammer), incus (anvil), and stapes (stirrup).
• The stapes, or stirrup, is the last bone in the chain and transmits sound vibrations to the inner ear.

Explanation

• When sound travels through air, the air particles vibrate back and forth along the direction of wave propagation.
• This means that the air particles oscillate in the same direction as the sound wave is traveling.
• It allowing the energy of the sound wave to be transmitted through the air.

Explanation

• Kinetic energy is the energy an object possesses due to its motion.
• Any moving object, such as a car, a ball, or a person, has kinetic energy.
• The amount of kinetic energy an object has depends on its mass and velocity.
