One cubic metre of water is taken in a strong cylinder and the pressure on it is increased from one atmosphere (`10^(5)` newtons per square metre) to two atmospheres. It is found that it has been compressed by only `50 c c`. Is this much sufficient for calculating velocity of sound in water?

The compressibility of water is 4xx10^-5 per unit atmospheric pressure. The decrease in volume of 100 cubic centimetre of water under a pressure of 100 atmosphere will be

540 calories of heat convert 1 cubic centimeter of water at C o100 into 1671 cubic centimeter of steam at C o100 at a pressure of one atmosphere. Then the work done against the atmospheric pressure is nearly

2 litres of moist hydrogen were collected over water at 26^(@)C at a total pressure of one atmosphere. On analysis, it was found that the quantity of H_(2) collected was 0.0788 mole. What is the mole fraction of H_(2) in the moist gas?

One cubic metre of argon at 27^(@)C is adiabatically compressed so that the final temperature is 127^(@)C . Calculate the new volume of the gas (gamma=5//3) .

Calculate the pressure of gas at constant volume , if a 10g of a gas at one atmospheric pressure is cooled from 273^@C " to "0^@C

A lamp of voume 50 cc was sealed off during manufacture at a pressure 0.1 newton per square metre at 27^(@)C . Calculate the mass of the gas enclosed in the lamp. Molecular weight of the gas =10 and R=8.3Jmol^(-1)K^(-1)

The total energy radiated from a block body source at constant temperature is collected for one minute and is used to heata quantity of water. The temperature of water is found to increase from 20^(@)C to 20.5^(@)C . If the absolute temperature of the blackbody is doubled and hte experiment is repeated with the same quantity of water of 20^(@)C , the temperature of water will be:
