A solid cube is floating (completely submerged) in a container filled with some liquid. The system is heated slowly. Ramesh states that cube will slowly sink. Suresh immediately responds that on the contary it will rise. Choose CORRECT statement(s)

A

Ramesh is right

B

Suresh is right

C

Without the knowledge of the thermal expansion coefficient of the cube and fluid, the question can not be decided clearly

D

One of them may be correct

Text Solution

Verified by Experts

The correct Answer is:
C, D

If the cube has a coefficient of thermal expension greater than liquid then buoyancy force will dominate

Figure shows a container filled with a liquid of density rho . Four points A, B, C and D lie on the vertices of a vertical square. Points A and C lie on a vertical line and points B and D lies on a horizontal line. Choose the correct statement(s) about the pressure at the four points.

Assertion : A solid floats in a liquid so that it is just submerged . When the liquid is heated the solid sinks to the bottom. Reason : Weight of the solid increases with the rise in temperature .

A solid cube floats in a liquid of density rho with half of its volume submerged as shown. The side length of the cube is a, which is very small compared to the size of the container. Now a liquid of density (rho)/(3) (immiscible with the liquid already in the container) is poured slowly into the container. The column of the liquid of density (rho)/(3) that must be poured so that the cube is fully submerged (with its top surface coincident with the surface of the poured liquid) is :

A small solid ball of density rho is held inside at point A of a cubical container of side L, filled with an ideal liquid of density 4rho as shown in the figure. Now, if the container starts moving with constant acceleration a horizontally and the ball is released from point A simultaneously, then choose from following the correct option(s)

An ideal monoatomic gas is confined in a horizontal cylinder by a spring loaded piston (as shown in the figure). Initially the gas is at temperature T_1 , pressure P_1 and volume V_1 and the spring is in its relaxed state. The gas is then heated very slowly to temperature T_2 ,pressure P_2 and volume V_2 . During this process the piston moves out by a distance x. Ignoring the friction between the piston and the cylinder, the correct statement (s) is (are)

Solids and liquids both expands on heating. The density of substance decreases on expanding according to the relation rho_(2) = (rho_(1))/(1 + gamma(T_(2)- T_(1))) , where , rho_(1) rarr "density at" T_(1) , rho_(2) rarr "density at" T_(2) , gamma rarr coefficient of volume expansion of substances. When a solid is submerged in a liquid , liquid exerts an upward force on solid which is equal to the weight of liquid displaced by submerged part of solid.
