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...

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...

QUESTION 15 Which statement A-D about the first law of thermodynamics (AEsystem-q+w) is not correct? O q is the energy added to or removed from the system by a temperature difference. O w is the energy added to or removed from the system by a deformation: that is, a force moves something. AEo stem is the change in the Gibbs free energy of the system. O If the only work that is done is P-V work, then q -the change...

The first law of thermodynamics D. The cylinder, with the piston still locked in place, is now immersed in a mixture of ice and water and allowed to come to thermal equilibrium with the mixture. The piston is then moved inward very slowly. in such a way that the gas is always in thermal equilibrium with the ice-water mixture. We will refer to this slow compression of the gas as process 3. 1. During process 3, do the following quantities...

The first law of thermodynamics In thermal physics, we are often interested in the internal energy (E) of a system. The wo 41 internal energy of an ideal gas is proportional to the temperature and the number of moles of the gas. The internal energy can change when energy is exchanged with the system's environment (ie., objects that are outside the system of interest). The case above is one in which the internal energy of a gas changes due to...

General Chemistry I Southern California University of Health Sciences Worksheet 3-Thermochemistry According to the First Law of Thermodynamics, total energy of the universe is constant: AE q+w, where w = -PAV; and at constant pressure, q AH 1. A system receives 212 cal of heat and delivers 435 cal of work to the surroundings. What is the change in internal energy of the system in Joules?

According to the Second Law of Thermodynamics A. the total entropy changes in any reaction that occurs spontaneously must be greater than 0. B. the total entropy changes in any reaction that occurs spontaneously must be less than 0. C. the total entropy of the universe remains constant. D. the total entropy of the universe is always decreasing.

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...
