The expansion of a substance on heating is called___expansion.

Thermal expansions of gases.

The decimal expansion of 1/9 is

The decimal expansion of sqrt2 is

Usually the thermal expansion of a liquid is greater than the thermal expansion of an equal volume of a solid'. State whether the statement is true or false.

Usually the thermal expansion of a liquid is greater than the thermal expansion of an equal volume of a gas'. State whether the statement is true or false.

Whether the following statement is 'true' or 'false'? The real, expansion of any liquid depends on the expansion of the vessel in which it is kept.

Give an example of volume expansion of a liquid on heating. The area of a solid substance at a temperature of T_1K is A_1 sq m and that at a temperature of T_2K is A_2 sq m.Write down the mathematical expression for the coefficient of area expansion-with unit, of that solid substance.

Expansion of a leaf is an example of

The expansion of a gas follows the condition pV^2 =constant .Show that such an expansion causes cooling of the gas.
