Assertion. At 298 K and 1 atm pressure, solids do not have any entropy but liquids and gases have definite values of entropy. Reason . At 298 K and 1 atm pressure, particle in a solid are fixed and do not have translatory, rotatory or vibraory motion whereas in liquids and gases, molecules have all the three types of motion.
