Pressure of 1 mol of an ideal gas confined in a cylinder fitted with a piston is 50 atm. The gas is expanded reversible when the cylinder is kept in contact to a thermostat at 25^(@)C . During expansion, the pressure of the gas is decreased from 50 to 5 atm. calculate the change in entropy in this process. if the heat absorbed by the gas during expansion be 5705J, then calculate the change in entropy of the surroundings ?
