A 700 g quantity of an ideal gas undergoes a reversible isothermal compression at a temperature of 330 K The compression reduces the volume of the gas from 0.40 m3 initially, to 0.15 m3 finally. The molecular mass of the gas is 380 g/mol What is the entropy change for the gas, in SI units?

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
