Maharashtra Board Science Most Important Questions and Answers

Below are chapter-wise important questions and their concise answers for Maharashtra SSC Board Science Part 1 (Physics, Chemistry, Biology). These are based on recurring board patterns and key concepts.

Chapter 1: Gravitation

Q1. State Newton’s Universal Law of Gravitation.

Newton’s Universal Law of Gravitation states that every object in the universe attracts every other object with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Q2. What is acceleration due to gravity? Write its value on Earth.

Acceleration due to gravity (g) is the acceleration produced in a body due to the gravitational force of the Earth. Its value on Earth is 9.8m/s².

Chapter 2: Periodic Classification of Elements

Q1. State Mendeleev’s periodic law.

Mendeleev’s periodic law: The properties of elements are the periodic function of their atomic masses.

Q2. What is the modern periodic law?

Modern periodic law: The properties of elements are the periodic function of their atomic numbers.

Chapter 3: Chemical Reactions and Equations

Q1. Define a chemical reaction.

A chemical reaction is a process in which one or more substances (reactants) are converted into one or more new substances (products) with different properties.

Q2. Balance the following equation: Fe+H₂​O→Fe₃​O4​+H_2​

Balanced equation: 3Fe+4H₂​O→Fe_3​O4​+4H_2​

Chapter 4: Effects of Electric Current

Q1. State Ohm’s Law.

Ohm’s Law: The current passing through a conductor is directly proportional to the potential difference across its ends, provided the temperature remains constant.

Mathematically: V=IR

Q2. What is the SI unit of electric current?

The SI unit of electric current is ampere (A).

Chapter 5: Heat

Q1. Define specific heat capacity.

Specific heat capacity is the amount of heat required to raise the temperature of 1 kg of a substance by 1°C (or 1 K).

Q2. State the principle of calorimetry.

The principle of calorimetry: Heat lost by hot body = Heat gained by cold body (if no heat is lost to surroundings).

Chapter 6: Refraction of Light

Q1. State Snell’s Law.

Snell’s Law: The ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant for a given pair of media.

Mathematically: sinrsini​=constant

Q2. What is the refractive index of a medium?

Refractive index (n) is the ratio of the speed of light in vacuum to the speed of light in the medium.

Chapter 7: Lenses

Q1. State the lens formula.

Lens formula: f1​=v1​−u1​ where f = focal length, v = image distance, u = object distance.

Q2. What is the power of a lens?

Power of a lens (P) is the reciprocal of its focal length in meters. P=f1​ (in dioptres, D)

Chapter 8: Metallurgy

Q1. What is metallurgy?

Metallurgy is the process of extraction of metals from their ores and refining them for use.

Q2. Name two methods of refining metals.

1. Electrolytic refining
2. Distillation

Chapter 9: Carbon Compounds

Q1. What is homologous series?

A homologous series is a group of organic compounds having the same functional group and similar chemical properties, with successive members differing by −CH2​− group.

Q2. Write the IUPAC name of CH3​CH2​OH.

IUPAC name: Ethanol

Chapter 10: Life Processes in Living Organisms

Q1. What is photosynthesis?

Photosynthesis is the process by which green plants prepare their own food using sunlight, carbon dioxide, and water, releasing oxygen as a byproduct.

Q2. Name the organelle where photosynthesis occurs.

Chloroplast

Chapter 11: Heredity and Evolution

Q1. What is heredity?

Heredity is the transmission of characteristics from parents to offspring through genes.

Q2. Who is known as the father of genetics?

Gregor Mendel

Chapter 12: Environment

Q1. What is ecosystem?

An ecosystem is a community of living organisms interacting with each other and with their non-living environment.

Q2. Name two greenhouse gases.

1. Carbon dioxide (CO2​)
2. Methane (CH4​)
