When 50 j of heat was supplied to the system, it did 30 j of work. What is the change in internal energy of the system?
Apply first law of thermodynamics
Q - W = dE
Q = +50 since it is inlet
W = 30 since it is done by the system
Q - W = dE
dE = 50-30 = 20 J
When 50 j of heat was supplied to the system, it did 30 j of work....
If 140 J of work is done by a system while 420 J of heat is transferred out of the system, what is the change in the internal energy of the system?
A system releases 110 J of heat and does 345 J of work on the surroundings. What is the change in internal energy (AU) of this system (in J)?
In process A, 48 J of work are done on the system and 72 J of heat are added to the system. Find the change in the system's internal energy. In process B, the system does 48 J of work and 72 J of heat are added to the system. What is the change in the system's internal energy? In process C, the system's internal energy decreases by 129 J while the system performs 129 J of work on its...
Suppose the work done to compress a gas is 100 J. If 70 J of heat is lost in the process, what is the change in the internal energy of the gas? Hint: Use the first law of thermodynamics. The internal energy of a system changes due to heat (Q) and work (W): U=Q-W. The change in internal energy is equivalent to the difference between the heat added to the system and the work done by the system. Think if...
A system releases 425 J of heat and performs 425 J of work to its surroundings. What is the change in internal energy of the system in calories? Please show the steps
A system does 5.0 × 104 J of work, and 8.7 × 104 J of heat flows into the system during the process. Find the change in the internal energy of the system. ΔU =
