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 )

What will be the percentage increases in its area if each side of square I increased by 10%

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

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 -

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?

For an ideal gas, C_(V)=(3)/(2)R . (a) What will be the change in internal energy (DeltaU) of 1 mole of an ideal gas if its temperature is increased by 4K at constant volume ? What would be DeltaU if the temperature of this gas is increased by the same amount of constant pressure? keeping pressure constant if the temperature of that same amount of gas is increased by 4K then what will be the change in internal energy (DeltaU) of that gas? (c) give reason for different values of DeltaU and DeltaH ?

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 :

Wooden block is floating on water having a temperature of 0^@C and its V volume Is outside of the water. If the temperature of water is increased from 0^@C to 20^@C what will be the effect on the volume V?
