Explanation
The Constituent Assembly of Pakistan was dissolved on October 24, 1954 By Governor General Malik Ghulam Muhammad. Additional information  The period of the Assembly was from 10 August 1947 to 24 October 1954. This action was take n amidst political tensions and efforts to revise the 1935 Government of India Act The Assembly passed the Objectives Resolution in 1949 Muhammad Ali Jinnah served as the first president of the Assembly until he died in 1948.  The first session was held at the Sindh Assembly Building, Karachi.

Explanation
Copper is an excellent conductor of heat , having a high thermal conductivity (386 W/mK). This means it can efficiently transfer heat energy with minimal resistance. Metals (e.g., iron, copper, silver, mercury, aluminum) are good conductors of heat.

Explanation
In solids, heat transfer occurs primarily through conduction , where vibrations and collisions of particles (atoms or molecules) transfer energy from one point to another.

Explanation
Conduction is the transfer of internal energy (heat) through direct contact between particles or molecules. Including collisions and movements of electrons within a substance. This process occurs in solids.

Explanation
Burning of wood is a chemical change , as it involves a chemical reaction between the wood and oxygen. Resulting in a change in chemical composition and the formation of new substances (ashes, carbon dioxide, water vapor, etc).

Explanation
Fertilizers are substances added to soil to provide essential nutrients for plant growth, making up for any deficiencies in the soil.

Explanation
Hydrocarbon compounds are typically derived from fossil fuels and consist of hydrogen and carbon atoms. Examples include fuels like gasoline, natural gas, and propane , as well as waxes like candle wax and paraffin wax.

Explanation
When fuel is burned , carbon dioxide gas (CO₂) is primarily produced. The combustion of fuel , particularly hydrocarbons, typically results in the formation of carbon dioxide and water vapor (H₂O).

Explanation
Melting of ice is a physical change , as it only involves a change in state (from solid to liquid) without a change in chemical composition. The examples of chemical changes: Burning of fuel Explosion of firework Burning of wood Cooking of food (breakfast, lunch, dinner) Bursting of crackers Burning of wax Rusting of iron Heating sulphur with iron fillings (to produce iron sulphide) Digestion of food Respiration in living things Photosynthesis in plants

Explanation
A chemical change , also known as a chemical reaction. It is a process that alters the composition of one or more substances, resulting in the formation of new substances with different properties.

Explanation
A change in physical appearance or state of a substance , such as a change in shape, size, color, or phase (solid, liquid, gas), is called a Physical Change. The are examples of Physical Changes: Melting (ice cream, wax, chocolate, ice and change from solid to liquid ) Phase changes ( boiling, freezing, condensation ) Crushing (chalk) Tearing (paper) Crumpling (aluminium foil) Stretching (rubber band) Mixing (sugar in water) Dissolving (sugar, salt in water) Moulding (clay, metals) Slicing (fruit) Forming of frost (from water vapors) Transition to a gas (change from liquid to gas) Change of durability (change in texture or strength) Changes to crystal form (change in crystal structure)
