Answer 2

Correspondence between Substances and their Properties:

1) Milk: Milk is a liquid substance that is commonly consumed as a beverage. It is a white or creamy-colored liquid produced by mammals, primarily cows. Milk is known for its nutritional value and is a rich source of calcium, protein, and various vitamins and minerals.

2) Cast Iron Block: Cast iron is a hard, brittle, and relatively inexpensive metal alloy that is primarily composed of iron, carbon, and silicon. It is known for its high strength and excellent heat retention properties, making it suitable for applications such as engine blocks, pipes, and cookware.

3) Hydrogen: Hydrogen is a colorless, odorless, and highly flammable gas. It is the lightest and most abundant element in the universe. Hydrogen is known for its low density and high energy content, which makes it a potential source of clean and renewable energy.

4) Kerosene: Kerosene, also known as paraffin oil, is a flammable hydrocarbon liquid. It is commonly used as a fuel for lamps, stoves, and jet engines. Kerosene is known for its high energy density and relatively low volatility, which makes it suitable for various combustion applications.

5) Nitrogen: Nitrogen is a colorless, odorless, and non-reactive gas. It is the most abundant element in the Earth's atmosphere, making up about 78% of the air we breathe. Nitrogen is known for its inert nature, which makes it useful for applications such as preserving food and creating an inert atmosphere in industrial processes.

6) Silver Goblet: Silver is a lustrous, white, and highly reflective metal. It is known for its excellent electrical and thermal conductivity, as well as its resistance to corrosion. Silver goblets or cups are often used for special occasions or as decorative items.

Properties:

A) Maintain Unchanged Shape and Volume: This property refers to substances that retain their shape and volume under normal conditions. Examples include solids like the cast iron block and silver goblet, which maintain their form and occupy a fixed amount of space.

B) Do Not Maintain Shape and Occupy Entire Volume Provided: This property refers to substances that do not retain their shape and instead take up the entire volume available to them. Liquids like milk and kerosene fall under this category, as they conform to the shape of their containers and fill the entire space provided.

C) Maintain Volume but Cannot Retain Shape: This property refers to substances that maintain their volume but are unable to retain a specific shape. Gases like hydrogen and nitrogen exhibit this property, as they expand to fill the entire volume of their container but do not have a fixed shape.
