About This Quiz

Science is the study of the world around us. Scientists learn about their subject by observing, describing, and experimenting. There are many subjects and branches of science. Some study outer space like astronomy. Other sciences study life (biology) or the earth (geology) or even matter and energy (physics).

    7.Which of these is hard?

    • Cotton

    • Glass

    • Flower

    Correct Answer
    A. Glass
    Explanation
    Glass is considered hard compared to cotton and flower because it is a solid material that is rigid and not easily deformed. It has a high level of hardness and can withstand pressure and impact without breaking or bending. Cotton, on the other hand, is a soft and flexible material, while flowers are delicate and fragile.

    2.change​ of liquid into vapour on heating is called------- 

    • Evopration

    • Warm

    • Stone

    Correct Answer
    A. Evopration
    Explanation
    Evaporation is the process in which a liquid changes into a vapor when heated. This occurs when the molecules of the liquid gain enough energy to break the intermolecular forces holding them together and escape into the air as gas. Evaporation is a natural process that happens at any temperature, but it occurs more rapidly at higher temperatures. It is an important part of the water cycle and is responsible for the formation of clouds, rainfall, and the cooling effect of sweating.

    5.An example for solid is______

    • Gas

    • Stone

    • Rain

    Correct Answer
    A. Stone
    Explanation
    An example of a solid is stone because it has a definite shape and volume, and its particles are closely packed together. Unlike gases, which do not have a definite shape or volume, and liquids like rain, which have a definite volume but not a definite shape, solids maintain their shape and do not flow. Stone, being a solid material, exemplifies these characteristics.

    1.The measure of matter in an object is called_________

    • Mass

    • Water

    • Soid

    Correct Answer
    A. Mass
    Explanation
    Mass is the measure of matter in an object. It represents the amount of material present in an object and is often measured in kilograms. Mass is different from weight, as weight is the force exerted on an object due to gravity. Mass remains constant regardless of the location, while weight can vary depending on the strength of gravity.

    3.An example for liquid is_______

    • Flow

    • Water

    • Gas

    Correct Answer
    A. Water
    Explanation
    An example of a liquid is water. Water is a substance that has a definite volume but no definite shape, conforming to the shape of its container. It flows easily and can be poured, making it a clear example of a liquid.

    10.Example of gases_____

    • Cloud

    • Ice

    • Stone

    Correct Answer
    A. Cloud
    Explanation
    A cloud is an example of a gas because it is composed of tiny water droplets or ice crystals suspended in the air. Clouds form when warm air rises and cools, causing the water vapor in the air to condense into visible water droplets or ice crystals. This process occurs in the atmosphere, where gases such as water vapor can exist in their gaseous state. Therefore, a cloud is a visible mass of gas.

    4.The change of liquid is______

    • Freezing

    • Stone

    • Juice

    Correct Answer
    A. Freezing
    Explanation
    The correct answer is "Freezing." Freezing refers to the process in which a liquid changes into a solid state due to a decrease in temperature. This change is characterized by the formation of ice crystals and a decrease in the liquid's viscosity. It is a common phenomenon observed in substances like water when exposed to low temperatures.

    8.Which of these is solid fuels?

    • Coal

    • Gas stove

    • Kerosene stove

    Correct Answer
    A. Coal
    Explanation
    Coal is a solid fuel because it exists in a solid state at room temperature and is commonly used for heating and energy production. Gas stove and kerosene stove, on the other hand, are not solid fuels as they rely on gaseous or liquid substances for combustion.

    9.Which of these is gaseous fuels?

    • LPG

    • Vegetable oil

    • Petrol

    Correct Answer
    A. LPG
    Explanation
    LPG (liquefied petroleum gas) is a gaseous fuel commonly used for heating, cooking, and in vehicles. It is a mixture of propane and butane, which are both gases at room temperature and pressure. Vegetable oil and petrol, on the other hand, are liquid fuels. Therefore, LPG is the only option among the given choices that is a gaseous fuel.
