In physics, the second law of thermodynamics states that the total entropy of an isolated system can only increase over time. The total entropy of a system can never decrease, and the entropy of a system approaches a constant value as the temperature approaches zero.

03:25

The First Law of Thermodynamics is an expression of the principle of conservation of energy. The law states that the change in the internal energy of a closed system is equal to the amount of heat energy added to the system, minus the work done by the system on its surroundings. The total energy of a system can be subdivided and classified in various ways.

disses Chapter 15. Problem number 18. I'm dressed to find a mess of a single serve. Self arrest Adam and an ammonia molecule in each three in Route Bus. To use the periodic table independence, see to find the Moler masses. So let's remember a couple of things you know, detention. This question. We need to know what the other bedroom Hamburg ISS it's going meets exploit and 0 to 2 attempts. Enter her three molecules. Her move right then the well, you can look up the mauler mess for sulphur, for example. Well, the master will suffer his 32.64 attempts center for negative three kilograms per roll and the older mass for a morning he is going to be bologna is going to be so. We have one Mac region there and three hydrogen correct. So we're going to have Teo look them up individually and add them accordingly. Right here for a nitrogen, we have 14.7 and then we have three hydrogen, so it's going to be 1.8 right times 10 Performing a three kilograms Promote my fees to our Moller masses. Right then, let's calculate what the molar s for. Harmonia is. It's gonna be 17 plaint 031 times into terminated three kilograms for home. Now, in order to calculate the mass that's remembered, a relationship right from Waller Mass equals to the l A crash or a number times the mass. So if you divide full size by the other govern under, then the master is it going to be cruel to the mauler mess? Whatever rule cannot divided by the Democrat, remember? And then you Well, what we need to do is just to apply this equation to off sulfur and ammonia, right? So for sulfur we have We were all a massive self serving five years for hacking number over meself self for his 32.64 times center forming into three kilograms for more over 6.0 to to test into power of 23 molecules divided by malls Permal. Right, so or sulfur. The mass that we have is going to be halted by 0.32 times static or negative. 26 kilograms further. Come on, you two. Right now, if you do the same for long, then you have the more massive among looks divided by the number. So it's 17 points here. 31 time center power made of three kilograms. Parole. Divine advice. Explain off 31 3 2 to 10 cents. Car 23. Well, thank you. No. Then we have right ISS 2.83 times center for negative. 26 kilograms Her
