This question consists of two statements each printed as assertion and reason. While answering this question you are required to choose any one of the five responses.

Assertion: In the siphon figure shown, $p_1=p_2$.

Reason: Pressure at $1$ is less than the atmospheric pressure.

This question consists of two statements each printed as assertion and reason. While answering this question you are required to choose any one of the five responses.

Assertion: If ice is floating in water and it melts, then level of water remains unchanged.

Reason: When the ice is floating, weight of liquid displaced is equal to the weight of ice.

This question consists of two statements each printed as assertion and reason. While answering this question you are required to choose any one of the five responses.

Assertion: An ice ball is floating in the water. Some stone pieces are embedded inside the ice. When ice will melt, the level of water will fall.

Reason: In a floating condition, stone pieces will displace more liquid compared to the condition when they sink.

This question consists of two statements each printed as assertion and reason. While answering this question you are required to choose any one of the following five responses.

Assertion: In a freely falling liquid container, the upthrust force is zero.

Reason: In freely falling case value of the effective value of $g$ is zero.

This question consists of two statements each printed as assertion and reason. While answering this question you are required to choose any one of the five responses.

Assertion: Bulk modulus of an incompressible liquid is infinite.

Reason: Compressibility is inverse of bulk modulus.

This question consists of two statements each printed as assertion and reason. While answering this question you are required to choose any one of the five responses.

Assertion: Density of an incompressible liquid is constant.

Reason: An ideal fluid is incompressible.

This question consists of two statements each printed as assertion and reason. While answering this question you are required to choose any one of the five responses.

Assertion: A solid object of iron is dipped in water, both are at the same temperature of $2 °\mathrm{C}$. If the temperature of the water is increased by $2 °\mathrm{C}$, then the buoyancy force action of the object will increase.

Reason: If we increase the temperature of water from $2 °\mathrm{C}$ to $4 °\mathrm{C},$ then density of a water will increase. Ignore expansion of solid sphere.

This question consists of two statements each printed as assertion and reason. While answering this question you are required to choose any one of the following five responses.

Assertion: A solid sphere and a hollow sphere both of same material is immersed in a liquid, then change in weight in both the spheres will be same.

Reason: Upthrust depends upon the volume of the solid immersed not the mass.

This question consists of two statements each printed as assertion and reason. While answering these question you are required to choose any one of the following five responses.

Assertion: If water is filled in a balloon and this is immersed in the water itself. Then the volume of water displaced is equal to the volume of water filled in the balloon.
Reason: Volume of a liquid displaced is equal to the volume of solid immersed in that liquid.
