Q5. Which planet is closest to the Sun?

Explanation

Mercury is the closest planet to the Sun and is the smallest planet in our solar system. It is the first planet from the Sun and revolves around it at an average distance of about 58 million kilometers (36 million miles). Due to its proximity to the Sun, Mercury experiences extremely high temperatures during the day and very low temperatures at night.

Mercury has the shortest orbital period among all the planets, completing one revolution around the Sun in approximately 88 Earth days. Unlike Earth, Mercury has a very thin atmosphere, which cannot retain heat effectively. As a result, the planet experiences drastic temperature variations, ranging from about 430°C during the day to -180°C at night.

Despite being the closest planet to the Sun, Mercury is not the hottest planet. Venus is actually the hottest planet because its thick atmosphere traps heat through the greenhouse effect.

Key Points:

• Mercury is the closest planet to the the Sun.
• It is the smallest planet in the solar system.
• Mercury completes one orbit around the Sun in about 88 Earth days.
• It has the shortest year among all planets.
• Mercury has a very thin atmosphere.
• Venus, not Mercury, is the hottest planet in the solar system.

Exam Tip:

📝 Remember the order of planets from the Sun:

Mercury → Venus → Earth → Mars → Jupiter → Saturn → Uranus → Neptune

Q9. Which gas is essential for combustion?

Explanation

Oxygen is the gas essential for combustion. Combustion is a chemical process in which a substance reacts rapidly with oxygen, releasing heat, light, and energy. Without a sufficient supply of oxygen, a fire cannot start or continue burning. This is why oxygen is often referred to as the supporter of combustion.

The process of combustion requires three essential elements: fuel, oxygen, and heat. These three components together form the Fire Triangle. If any one of these elements is removed, the combustion process stops. For example, firefighters extinguish fires by removing heat (using water), cutting off oxygen (using fire blankets or foam), or removing the fuel source.

Although oxygen supports burning, it is important to note that oxygen itself does not burn. Instead, it helps other substances burn more efficiently. This principle is used in industries, laboratories, power plants, and everyday activities such as cooking and transportation.

Key Points:

• Oxygen is essential for combustion.
• Combustion is a chemical reaction that releases heat and light.
• Oxygen is known as the supporter of combustion.
• The Fire Triangle consists of Fuel, Heat, and Oxygen.
• Removing any one of the three elements stops combustion.
• Oxygen itself does not burn; it supports burning.

Exam Tip:

📝 Remember the Fire Triangle:

• Fuel + Heat + Oxygen = Fire
• Remove any one component → Fire stops

Related Facts:

• Oxygen → Supports combustion
• Carbon dioxide → Used to extinguish fires
• Nitrogen → Does not support combustion

✅ Answer: D. Oxygen
