Top 10 SEBA Class 10 Science Questions & Answers
-
Question: What is the principle of conservation of mass?
Answer: In a closed system, the total mass of reactants equals the total mass of products during a chemical reaction. -
Question: Define refraction of light.
Answer: Refraction is the bending of light as it passes from one medium into another with a different density. -
Question: State Ohm’s Law.
Answer: The current through a conductor between two points is directly proportional to the voltage across the two points (V = IR). -
Question: What are autotrophs?
Answer: Autotrophs are organisms like plants that can synthesize their own food using sunlight (photosynthesis). -
Question: Explain the function of the human heart.
Answer: The heart pumps oxygenated blood to the body and deoxygenated blood to the lungs in a double‑circulation system. -
Question: What is an endothermic reaction?
Answer: A reaction that absorbs heat from its surroundings, leading to a temperature drop in the surroundings. -
Question: Describe the role of stomata in leaves.
Answer: Stomata are tiny pores on leaves that regulate gas exchange (CO₂ in, O₂ out) and transpiration. -
Question: Define velocity and speed.
Answer: Speed is the rate of change of distance, while velocity is speed with a specified direction. -
Question: What is alloy? Give an example.
Answer: An alloy is a homogeneous mixture of two or more metals (e.g., brass = copper + zinc). -
