The freezing point of the liquid decreases when pressure is increased, if the liquid

An external pressure $P$ is applied on a cube at $0^o C$ so that it is equally compressed from all sides. $K$ is the bulk modulus of the material of the cube and a is its coefficient of linear expansion. Suppose we want to bring the cube to its original size by heating. The temperature should be raised by

A piece of metal weight $46\, gm$ in air, when it is immersed in the liquid of specific gravity $1.24$ at $27°C$ it weighs $30\, gm.$ When the temperature of liquid is raised to $42°C$ the metal piece weight $30.5\, gm,$ specific gravity of the liquid at $42°C$ is $1.20,$ then the linear expansion of the metal will be

What is thermal expansion ? Write only its types.

What will be the difference in volume of water when it is heated from $0\,^oC$ to $10\,^oC$ ?

Ratio among linear expansion coefficient ($\alpha$), areal expansion coefficient ($\beta$) and volume expansion coefficient ($\gamma$) is
