Answer #1

5. Thermodynamics is the study of energy where "thermos" refers to heat and "dynamics" refers to motion of molecules.

It deals with conservation of energy and transformation of different forms of energy from one form to another, for example, conversion of heat to work or heat to kinetic energy,

1st law of thermodynamic refers to conservation of energy , 2nd law gives important criteria for a process to be spontaneous or non-spontaneous, using the parameter called entropy. 3rd law provides ways to calculate absolute entropy of a substance which was not possible using 2nd law.

This is a Thermodynamics course A commonly used unit for gas pressure is torr, where 1 atmosphere = 760 torr, and 1 atmosphere is 1.01 x 105 Pascals, where a Pascal is Newtons/m2. For a pure ideal gas at a very low pressure of 1 torr and a temperature T = 310 K, how many molecules would be present in 1 cubic centimeter? Show your work. (Hint: Recall that PV = NkBT, where N is the number of molecules, and...

Thermodynamics Question A Joule expansion refers to the expansion of a gas from volume V1 to volume V2against no applied pressure, and is sometimes also called a free expansion. There is no work done, because the P of -PdV is zero. By insulating the system, this process can be done adiabatically, so there is no change in heat. For an ideal gas, the adiabatic process is also isothermal, so there is no change in thermodynamic energy, ∆U = 0 (which...

The first law of thermodynamics is ΔU 5 Q 1 W. For each of the following cases, state whether the internal energy of an ideal gas increases, decreases, or remains constant: (a) No energy is transferred to the gas as it expands to twice its original volume. (b) The gas volume is held constant while energy Q is removed. (c) The gas volume is held constant and no energy is transferred to or from the gas. (d) The gas temperature...

5. The term sustainability refers to the concept of meeting the needs of the present without compromising the ability of future generations to meet their future needs. A. True            B. False. 6. What implication(s) does the law of conservation of matter have for humans? A. We cannot produce energy because it is neither created nor destroyed. B. As matter is recycled it loses its integrity so we need to be careful when we dispose of goods. C. Natural resources are unlimited....

Suppose that there are two energy firms with identical technology, where their marginal cost is MC = 100 - Q/5. Let the marginal willingness to pay for energy be MWTP = 310 - 4Q/5 (and the marginal revenue is MR = 310 - 8Q/5). a) If there was only one firm supplying energy, and this firm was acting as if the market was competitive, how much energy would be supplied? b) If the two firms are supplying energy, and both...

this is a thermodynamics class 4. We want to develop an intuition for what different amounts of energy look like in various forms. Calculate the energy in MegaJoules (MJ) present in the following systems. As a comment, many people will be surprised by some of the values, for example, a comparison of part e to parts a through c. a) 1 liter (approximately 1 quart) of octane, a primary component of gasoline. In this case, the chemical energy is released...
