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. 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. Consider a disk made of copper, with a specific heat capacity of 0.093 cal/g·C°. How much heat must be removed from a 130 g disk to lower its temperature from 150°C to 24°C? ____ cal 2.A cylinder of gas is heated, with, 870 J of heat is added to the gas. The gas does 160 J of work on its surroundings in this process. What is the change in the internal energy of the gas? ____ J
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
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...
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,
