We did an experiment : determination of entropy changes during melting of ice in a closed system. Can you write a 400 words paragraph introduction about The Second Law of Thermodynamics, entropy, entropy changes in reversible and irreversible processes, methods of calculating entropy changes in isothermal, isobaric and isochoric processes and entropy of the phase transformation.

In your own words. No copy-paste from the internet. Pleasee!!

Temperature during Phase Changes 1. Imagine you have a block of steel much below its melting temperature and you start heating it. What happens to its temperature? (I said that the temperature does not increase) 2. The same block has now reached its melting point and is just starting to melt. You still keep adding head to it. What happens to its temperature? (I said that the temperature remains at the melting point until the block is completely melted) 3....

In a gas forming experiment, we did not consider the volume of the reactants occupy in the baggie when we did our calculations for the reactant amounts. Will this oversight cause the pressure inside the bag after the reaction to be higher or lower than the atmospheric pressure in the lab?

In our physics lab, we did a experiment regarding Hooke's law, and the goal is to find the spring constant by using a simulation. In the first section of the procedure, our instructor intentionally give us the wrong instruction, which tells us to find spring constant using varying mass, delta x and constant gravity. In the second section of the procedure, we need to figure out what went wrong in the first section that caused us to incorrectly measure the...

During the 20th century, what role did changes in innovation, technology, and communication play: in the decline of agriculture’s relative size (in terms of # of jobs) while simultaneously allowing for agricultural production to significantly increase? in the decline of manufacturing’s relative size, (in terms of # of jobs) resulting in a fourfold increase in the amount of manufactured goods with only a 20% increase in manufacturing employment? growth in the services sector? growth in international trade?

We did Knoevenagel-Robinson experiment in organic lab. To check for the product's purity (ethyl 3-coumarincarboxylate), we used the thin layer chromatography technique. We dissolved a small amount of the solid crystals in dichloromethane and added a drop of the solution to a plate. Then, we ran the chromatography. We used two mobile phases in two different beakers. One contained 10% ethyl acetate/hexane solution and the other contained 20% ethyl acetate/hexane solution. We put a plate containing a drop of the...

Chemistry question: We did an experiment in lab and I need to figure out how to A) calculate the mols of NaOH used in titration B) calculate mols HCl in titration C) calculate mols of CaCO3 reacted D) calculate grams of CaCO3 reacted E) calculate percentage of CaCO3 in TUMS. I really need to see all the steps that way I can understand what is going on. We did four titrations with the following information 38 mL HCl, 19.913 g...

I recently did an experiment where we had to discover the rate order of the sufrace area of magnesium and hydrochloric acid as well as the activation energy. The point of the experiment was to discover the kinetic parameters of a heterogenous reaction. As I was writing my lab report, I uncovered a similiar experiment however the rate order for their experiment for hydrochloic acid was 2 when mine came out as 1. So I was curious as to how...

Thought Experiment: We have studied the open-closed resonator in air. Let’s turn our focus to other gases: helium (He) and sulfur hexafluoride (SF6). Helium is lighter than air. SF6 on the other hand is heavy, almost 5 time heavier than air. How would each gases speed of sound compare to that of air? Higher? Lower? The same? How do you expect the resonator to react in each gas?
