A. If a system has absorbed 48.62 Cal of heat and did 112.15 Joule of work to the surroundings, what is the change to the system's internal energy during the whole process?
A system conducts 120 cal of heat to the surroundings while delivering 254 cal of work. What is the change in internal energy of the system (in kJ, mind the signs of these energy terms )? (a) ‒1.56 kJ (b) ‒0.561 kJ (c) ‒0.0894kJ (d) 0.561 kJ (e) 1.56 kJ
Three different processes act
on a system. In process A, 53 J of work are done on the system and
77 J of heat are added to the system. Find the change in the
system's internal energy. In process B, the system does 53 J of
work and 77 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 125 J while the system...
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...
1.) A system absorbs 1.56E+2 kJ of heat and the surroundings do 1.107E+2 kJ of work on the system. What is the change in internal energy (in kJ) (ΔU) of the system? 2.) A sample of gas in a cylinder is provided with 6.221E+2 kJ of heat. This causes a piston to then compresses the gas by doing 4.343E+2 kJ of work to the gas. What is the change in internal energy of the gas during this compression? 3.)A gas...
2. Work and Heat. Calculate the change in the internal energy of the system for a process in which the system absorbs 140 J of heat from the surroundings and does 85 J of work on the surroundings,
If a system has 3.50 x 102 kcal of work done to it, and releases 5.00 x 102 kJ of heat into its surroundings, what is the change in internal energy (AE or AU) of the system? AE=
Consider another system which gave out 62.55 Cal of heat, what kind of work would be needed in order to keep the internal energy of the system unchanged? Hint: the magnitude of the work and sign of the work (work done to the system or done by the system to surroundings)
on 4 of 15 A system does 501 kJ of work and loses 286 kJ of heat to the surroundings What is the change in internal energy, AE, of the system? Note that internal energy is symbolized as AU in some sources. AE = kJ
If a system has 375 kcal of work done to it, and releases 5.00 x 10 kJ of heat into its surroundings, what is the change in internal energy (AE or AU) of the system? - - AE = |
