The first law of thermodynamics is usually written as Q=W+?U. You need to look at the signs carefully; some other disciplines (chemistry, for example) may use other signs, which implies other definitions of these quantities. 1-Which physical law underlies the first law of thermodynamics? -conservation of matter -increase in entropy -conservation of energy -conservation of work 2- The quantity Q is the __________ that is added to the system. -heat - work -entropy -internal energy 3-The quantity W in the...

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...

Identify the three statements from the list below that BEST describe the first law of thermodynamics. A. The energy gained or lost by a system must equal the energy lost or gained by the surroundings. B. The total energy of the universe is decreasing. C. The work done by a system equals the work done on the surroundings. D.ΔE = Efinal – Einitial E. Heat released by the system is absorbed by the surroundings. F.ΔE = q + w G.Energy...

The first law of thermodynamics is a statement that energy is conserved. If the work out of a system is greater than the heat being put in, what happens to U (internal energy)?

10. According to the first law of thermodynamics, the energy of the universe is constant. Does this mean that AE is always equal to zero? a. Yes, AE = 0 at all times, which is why 9 = -W. b. No, AE does not always equal zero, but this is only due to factors like friction and heat. c. NO, AE does not always equal zero because it refers to the system's internal energy, which is affected by heat and...
