Thermal Expansion

What does coefficient of volume expansion means?

What does coefficient of linear expansion means? Write its unit.

The expansion of a substance on heating is called the thermal expansion of that substance.

What is thermal expansion? Explain different types of expansion.

Real and apparent expansion are the two types of liquid expansion.

Liquids normally expands on increase in temperature.

Volume expansion is proportional to temperature change.

Volume expansion is linear for a small temperature change.

Linear expansion is directly proportional to the length of the material.

Linear expansion is directly proportional to the temperature.

Describe the expansion of solids on heating.

Solids expand on heating.

A flask contains $100cc$ of a liquid at $10°C$.when it is heated to $110°C$ increase in volume of the liquid appears to be $2cc$. The coefficient of real expansion of the liquid is _____$\times {10}^{-4} /°\mathrm{C}$.($\alpha$ of flask is $11\times {10}^{-6} /°C$)

A metal plate of area$1.2{\mathrm{m}}^2$Increases its area by $2.4\times {10}^{-4}{m}^2$When it is heated from $0°\mathrm{C} to 100°\mathrm{C}$. The coefficient of cubical expansion of the metal expressed in $/°\mathrm{C}$ is

The coefficient of linear expansion of a metal is $1\times {10}^{-5}/°\mathrm{C}$. The percentage increase in area of a square plate of that metal when it is heated through$100°\mathrm{C}$ is​_____

Most matter contracts on heating and expands on cooling (Yes\No).

The coefficient of volume expansion increases with the increase in the temperature of the gas: (Yes\ No).

Co-efficient of linear, superficial and volumetric expansions are $\mathrm{\alpha }$, $\mathrm{\beta }$ and $\mathrm{\gamma }$ respectively. The volume of $\mathrm{\alpha }:\mathrm{\beta }:\mathrm{\gamma }$ is 

The cause of irreversibility of a natural process is:

What is the unit of latent heat? (Choose from newton, joule, celsius)
