Three friends A, B and C worked together to complete the work. A takes 4 days more to complete same work done by A and B. Work done by C in 4 days is equal to the work done by A in one day. Work done by B in 3 days is equal to the work done by C in 8 days. Find the time in which work will be completed if all three worked together.
When a system is taken from state ‘x’ to state ‘y’ then 30 kJ of heat flows into the system and the system does 10 kJ of work. When the system is returned from state ‘y’ to state ‘x’ along another path, then work done on the system is 8 kJ. What is the amount of heat liberated?
Work done by A in one day is 2 times of the work done by B in one day. Work done by B is 3 times of the work done by C. If C can alone complete the work in 35 days, In how many days can A, B, and C together complete the work?
Work done by A in one day is half of the work done by B in one day. Work done by B is half of the work done by C in one day. If C alone can complete the work in 7 days, in how many days can A, B and C together complete the work ?
For a steady state system, 10 J of heat is supplied to the system, what is the work done by the system?
85 kJ of heat is supplied to a closed system at constant volume. During the next process, the system rejects 90 kJ of heat at constant pressure while 20 kJ of work is done on it. The system is bought to the original state by adiabatic process. The initial internal energy is 100 kJ. Then what is the quantity of work transfer during the process?
P can complete ¼ of some work in 10 days, Q can complete 40% of the same work in 48 days. R completes 1/8 of the work in 5 days and S does 1/10 of the work in 2 days. ½ of total work is done by (Q + R) and remaining work is done by (P + S). What will be the ratio of the days for completing ½ of work by (Q + R) and remaining work by the (P + S)?
5 J of heat is supplied to a steady state system, what is the work done by the system?
15 J of work is done by a steady state system, what is the heat supplied to the system?
25 J of work is done by a steady state system, what is the heat supplied to the system?
