A flat uniform cylinder of lead floats in mercury at `0^(@)C`. Will the lead float higher or lower when the temperature is raised?

An iron cube floats in a bowl of liquid mercury at 0^(@)C a. if the temperature is raised to 30^(@)C will the cube float higher or lower in the mercuyr? B. By wat percent will the fraction of volume submerged change?

When a piece of metal floats in mercury at T^@C , a fraction f_1 of its volume is submerged. If their temperature is increased by Delta T ""^@C , fraction f_2 of metal piece is seen to be submerged. If the coefficients of volume expansion of the metal and the mercury are gamma_1 and gamma_2 , respectively, then the ratio f_1//f_2 is

A glass flask of volume 200cm^(3) is just filled with mercury at 20^(@)C . The amount of mercury that will overflow when the temperature of the system is raised to 100^(@)C is (gamma_(glass)=1.2xx10^(-5)//C^(@),gamma_(mercury)=1.8xx10^(-4)//C^(@))

A block of wood is floating on water at 0^(@)C with a certain volume V above water level. The temperature of water is slowly raised to 20^(@)C . How does the volume V change with the rise of temperature ?

A cylinder of height 1m is floating in water at 0^@C with 20cm height in air. Now temperature of water is raised to 4^@C , height of cylnder in air becomes 21cm. the ratio of density of water at 4^@C to density of water at 0^@C is - (consider expansion of cylinder is negligible)

A platinum sphere floats in mercury. Find the percentage change in the fraction of volume of sphere immersed in mercury whenthe temperature is raised by 80^@C (volume expansivity of mercury is 182xxxx10^(-6)//^(@)C and linear expansivity of platinum 9xx10^(-6)//^(@)C )

A vertical cylinder of height 1.52m is fitted with a movable piston of negligible mass and thickness. The lower half of the cylinder contains ideal gas and upper half is filled with Hg. The cylinder is initially at 300K. When the temperature is raised, half of the mercury comes out of cylinder. The temperature is: (Assume no thermal expansion for Hg)

A block of wood is floating on water at 0^@C , with a certain volume V above water level. The temperature of water is slowly raised from 0^@C . How will the volume V change with the rise of temperature?

A block of wood is floating on water at 0^(@)C with volume V_(0) above water. When the temperature of water increases from 0 to 10^(@)C , the change in the volume of the block That is above water is best described schematically by the graph

A block of wood is floating on water at 0^@C with a certain volume V above the level of water. The temperature of water is gradually increased from 0^@C to 8^@C . How does the volume V change with the change of temperature ?
