When an explosive is detonated inside a shell or cartridge case, the explosion effectively takes places in a closed or fixed volume container. (The chemical decomposition is fast compared to the rate at which the projectile can gain velocity.) You can make an estimate of the explosion temperature if you assume a constant volume, and if you know the chemical equation for the decomposition and have an estimate of the constant-volume heat capacities of the gases produced by the detonation. The explosive RDX decomposes according to the balanced equation C3H6N6O6 -->3CO + 3H20 + 3N2. Approximate values of C(subscript v) of the product gases are CO = 27 J/mol/K, H20 = 41 J/mol/K, and N2 = 27 J/mol/K. Estimate the explosion temperature of RDX from its detonation energy of -1119 kJ/mol.

Calculate the work done (in joules) when 3.0 mole of water is frozen at 0°C and 1.0 atm. The volumes of three moles of water and ice at 0°C are 0.0540 L and 0.0588 L, respectively.
I tried 3960J but i am way off. Where am I going wrong?

I was just wanting to see the steps in between for the two highlighted equations in the attached file from Schrodinger's Statistical Thermodynamics text. I just cannot seem to come up with the same 2nd equation in my calculations. Thank you very much! (the 'log' in the text is actually 'ln' or log base e)

Which of the following statements is contrary to the first law of thermodynamics?
a. when gasoline is burned, its energy is destroyed.
b. energy can be transferred from one form to another
c. energy can be converted from one form to another
d. matter can be converted into energy
e. the amount of energy in the univers

(Please see the attachment for detailed problem description)
Distinguish between reversible and irreversible processes in thermodynamics. Describe the circumstances under which a) dQ = Tds and dW = -PdV.
A long cylinderical rod of radius R is attached to a source of heat at one end and its surroundings are at temperature

Some people claim that biological evolution violates the second law of thermodynamics, since evolution involves simple life forms developing into more complex, more highly ordered organisms. Why is this argument wrong?
I'm pretty sure that the answer lies in the definition of entropy. Doesn't entropy limit itself to energ

1. Which one of the following is a correct statement of the first law of thermodynamics?
a. ΔS = q - T
b.at absolute zero, for a pure crystalline solid, S = O
c. ΔS >or equal q/T
d. ΔH = ΣΔHproducts - ΣHreactants
e. ΔE = q + w
2. A reversible process is one that ________.
a. must be carried out at high

An ideal gas mixture consists of 3 kg of Ar and 6 kg of CO2 gases. The mixture is now heated at constant volume from 250 K to 350 K. The amount of heat transfer is:

Thermodynamics texts use the relationship (dy/dx)(dz/dy)(dx/dz) = -1
Prove that this equation is true.
(Hint: Start with a relationship F(x,y,z)= 0 that defines x = f(y,z), y = g(x,z), and z = h(x,y) and differentiate implicitly.)
