100 c.c of air are measured at `20^@C` .If the temperature be raised to `50^@C`, what will be the volume, pressure remaining constant.

Calculate the temperature at which RMS velocity of a gas is half its value at 0^@c , pressure remaining constant.

The rate of a chemical reaction doubles for every 10°C rise in temperature. If the temperature is raised from 10° to 30°C, what will be the increase in the rate of the reaction?

The volume of metalic ball is 100 cc at 0^@C . When its temperature is raised to 150^@C , its volume becomes 100 .81 cc . Find the coefficient of linear expansion of the metal.

The rate of a chemical reaction doubles for every 10^@C rise of temperature. If the temperature is raised by 50^@C , the rate of reaction increases by about.

When 80 litres of a gas at 27^@C and 10 atmospheres is reduced to 50 litres by increasing the pressure, the temperature increases to 37^@C . What is the final pressure on the gas assuming it to be ideal ?

300 cc of a gas are heated from 27^@C to 127^@ C . What will be the new volume at constant pressure ?

When the pressure of an enclosed gas is doubled, the temperature rises from 0^@ to 227^@C. How is the volume altered ?

What is the change in the activation energy if the temperature is raised by 10°C?
