HBSE Class 10 Science

Section A: Multiple Choice Questions (MCQs)

1. Which of the following is an example of a chemical change?

  1. a) Boiling water
  2. b) Melting ice
  3. c) Burning paper
  4. d) Cutting a piece of wood

Answer: c) Burning paper

2. The process of conversion of a solid directly into a gas is called:

  1. a) Melting
  2. b) Evaporation
  3. c) Condensation
  4. d) Sublimation

Answer: d) Sublimation

3. Which of the following is a greenhouse gas?

  1. a) Oxygen
  2. b) Nitrogen
  3. c) Carbon dioxide
  4. d) Hydrogen

Answer: c) Carbon dioxide

Section B: Short Answer Questions

1. Define photosynthesis and write its chemical equation.

Answer: Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen. The chemical equation for photosynthesis is:

6CO2 + 6H2O + sunlight → C6H12O6 + 6O2

2. What is the function of the nervous system in the human body?

Answer: The nervous system is responsible for coordinating and controlling the activities of the body. It receives information from the sensory organs, processes it, and sends signals to the muscles and glands to carry out appropriate responses.

Section C: Long Answer Questions

1. Explain the process of digestion in humans.

Answer: Digestion in humans is a complex process that involves the breakdown of food into simpler forms that can be absorbed by the body. It can be divided into two main processes: mechanical digestion and chemical digestion.

In mechanical digestion, the food is physically broken down into smaller pieces through chewing and mixing with digestive juices. This increases the surface area of the food, making it easier for enzymes to act on it.

In chemical digestion, enzymes break down complex molecules into simpler ones. For example, amylase breaks down starch into glucose, protease breaks down proteins into amino acids, and lipase breaks down fats into fatty acids and glycerol.

The digested food is then absorbed by the small intestine into the bloodstream and transported to the cells of the body, where it is used for energy, growth, and repair.

2. Explain the concept of force and give examples of different types of forces.

Answer: Force is a push or a pull that can change the state of motion of an object. It can cause an object to move, stop, or change direction.

There are different types of forces, including:

  • Gravity: The force that pulls objects towards each other. For example, the force that keeps us on the ground.
  • Friction: The force that opposes the motion of objects that are in contact with each other. For example, the friction between the tires of a car and the road.
  • Electromagnetic force: The force that acts between electrically charged particles. For example, the force that holds electrons in orbit around the nucleus of an atom.
  • Applied force: The force that is applied to an object by another object or a person. For example, pushing a door to open it.

These are just a few examples of the different types of forces that exist. Understanding the concept of force is essential in the study of physics and helps explain the behavior of objects in the physical world.

So, these were some of the questions from the HBSE Class 10 Science question paper of 2024 along with their answers. We hope that this blog post has been helpful in your preparation for the examination. Good luck!
