A system absorbed 150j of heat. If there is 50j of work done by the system,...
Marks: 1 When work is done on the system and heat is absorbed by the system, the sign on both work and heat are Choose one answer. A. work > 0 and heat > 0. B. work > 0 and heat < 0. C. work < 0 and heat > 0. D. work < 0 and heat < 0.
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?
Question 13 1 pts When heat is absorbed by the system and work is done by the system on the surroundings then both q and ware positive. both , and w are negative. O qis positive and wis negative. qis negative and wis positive. both q and w are zero. 1 pts
Assume no heat is exchanged in the following scenarios. If the work done on a system by external forces is zero, the change in total energy of the system [ Select ] ["is positive", "is negative", "is zero", "cannot be determined without additional information"] . If the work done on a system by external forces is positive, the change in total energy of...
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. 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?
1. a) How much work is done by/on the system when is taken from point a to point b following the path indicated in the figure? b) How much heat is absorbed/released by the system when is taken from point a to point b following the path indicated in the figure? Express your answer in kJ c) What is the change in internal energy, ?U? Express your answer in kJ. 2. a) How much work is done on the system...
A system absorbs 12 of heat from the surroundings; meanwhile, 28 of work is done BY the system. What is the change of the internal energy of the system? -40 J -16 J 16 J 40 J
CATES UI Work to the system. What is the change in energy 3. What is the change in energy if 0.615 kJ of heat is absorbed and 0.247 calories of work is done on the system?
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...
