4. The number of microstates in a system containing Noscillators and q quanta is given by the following equation: (N+9-1)! W= (N-1)!q! Consider two different systems, where system A contains 6 oscillators and 15 quanta of energy, and system B contains 5 oscillators and 18 quanta of energy. a. How many microstates does each system have the number is big!)? b. Make a small change in energy d by adding one quantum to each system. How many microstates does each system have now? C. Calculate the change "d InW for each system that results from addition of that quantum. d. Calculate the temperature of each system if a single quantum contains 1*10-20 Joules of energy (a reasonable value for a real molecule). Which direction will heat flow if the two systems are brought into contact
