Calculate the Percentage change of velocity of sound when the temperature is increasing from `10^@C` to `20^@C`.

What will be the percentage change in velocity of sound if the temperature is increased from 10^@C to 20^@C ?

If the temperature is increased (above 35^(@)C )

At normal temperature and pressure the velocity of sound in air is 330 m/s . If the temperature increased to 30^@C and the pressure remains the same the velocity of sound in air will be

A wooden block is floating on water at 0^(@)C keeping a portion V of its volume outside water. If the temperature of the water is increased from 0^(@)C to 20^(@)C , then what change of V will be observed?

The activation energy of a reaction is 12.89 kcal/mol. The increase in the rate constant when its temperature is increased from 27^@C to 37^@C is :

In a zero order reaction for every 10^(@)C rise of temperature , the rate is double . If the temperature is increased from 10^(@)C " to " 100^(@)C , the rate of the reaction will become -

The pressure exerted by 12 g of an ideal gas at temperature t^@C in a vessel of volume V litre is one atm.when the temperature is increased by 10 degree at the same volume.the pressure increases by 10% calculate the temperature t and volume v.(molecular weight of the gas =120).

A thin square metal plate has side of length l_(0) . When the temperature of the plate is raised from 0^(@)C " to " 100^(@)C , its length increased by 1%. What is the percentage increase in area of the plate in this case?
