Which of the following statements about water is true?
The correct answer is: (a) 71 per cent of the world's surface is covered with water, but 97 per cent of that is salt water Explanation: Water distribution on Earth: About 71% of Earth's surface is covered with water. 97% of Earth's water is saltwater found in oceans and seas. Only 3% of Earth's wateRead more
The correct answer is: (a) 71 per cent of the world’s surface is covered with water, but 97 per cent of that is salt water
Explanation: Water distribution on Earth: About 71% of Earth’s surface is covered with water. 97% of Earth’s water is saltwater found in oceans and seas. Only 3% of Earth’s water is freshwater, and most of it is locked in glaciers, ice caps, and underground sources. This question related to Chapter 3 Social Science Class 9th NCERT. From the Chapter 3 Drainage. Give answer according to your understanding.

Which river makes the second biggest waterfall i.e., Shivasamudram Falls in India?
The correct answer is: (b) Kaveri ✅ Explanation: Shivasamudram Falls is the second biggest waterfall in India in terms of water volume and is formed by the Kaveri River in Karnataka. The Kaveri River flows through Karnataka and Tamil Nadu. The Shivasamudram Falls is a segmented waterfall, meaning itRead more
The correct answer is: (b) Kaveri ✅
Explanation: Shivasamudram Falls is the second biggest waterfall in India in terms of water volume and is formed by the Kaveri River in Karnataka.
The Kaveri River flows through Karnataka and Tamil Nadu.
The Shivasamudram Falls is a segmented waterfall, meaning it is divided into multiple streams.
It is also home to one of India’s first hydroelectric power stations, built in 1902. This question related to Chapter 3 Social Science Class 9th NCERT. From the Chapter 3 Drainage. Give answer according to your understanding.

The root mean square (rms) speed of gas molecules is given by:
The root mean square speed of gases molecules is provided by: vₘₛ = √(3RT/M) - Here:, R: It is the Universal Gas Constant, T : This is Absolute temperature M : It refers to molar mass of a gas. Here this formula provides a condition showing that rms increases with an increment in temperature while tRead more
The root mean square speed of gases molecules is provided by:
vₘₛ = √(3RT/M)
– Here:,
R: It is the Universal Gas Constant,
T : This is Absolute temperature
M : It refers to molar mass of a gas.
Here this formula provides a condition showing that rms increases with an increment in temperature while the rms declines as molar mass increases.

The average kinetic energy of a gas molecule is directly proportional to:
The average kinetic energy (KE_avg) of a gas molecule is given by: KE_avg = (3/2) k_B T where: - k_B is Boltzmann's constant, - T is the absolute temperature. Since KE_avg ∝ T, the average kinetic energy of a gas molecule is directly proportional to the temperature in Kelvin. This means that as tempRead more
The average kinetic energy (KE_avg) of a gas molecule is given by:
KE_avg = (3/2) k_B T
where:
– k_B is Boltzmann’s constant,
– T is the absolute temperature.
Since KE_avg ∝ T, the average kinetic energy of a gas molecule is directly proportional to the temperature in Kelvin. This means that as temperature increases, the kinetic energy of gas molecules also increases.

Forces of attraction are (a) maximum in solids and minimum in gases. (b) maximum in gases and minimum in solids. (c) maximum in liquids and minimum in gases. (d) maximum in gases and minimum in liquids.
(a) Maximum in solids and minimum in gases. In solids, particles are tightly packed with strong intermolecular forces, keeping them in fixed positions. In gases, particles are far apart with very weak forces of attraction, allowing them to move freely. https://www.tiwariacademy.com/ncert-solutions/cRead more
