Divide then write answer in simplest form

Updated, new, and improved! Little did I know that this simple method and terrible video would be one of my most viral principles ever! Then, after you watch the video, come back for a few additional tips and clarifications.

In any process, energy can be changed from one form to another, including heat and work, but it is never created or destroyed.

InSadi Carnot gave a fundamental limitation of steam engines by analyzing the ideal engine now named after him, which turns out to be the most efficient of all possible heat engines. It increases in any non-reversible transformation. Hot A to B slow isothermal expansion. Cooling B to C adiabatic expansion.

The gas keeps working without any exchange of heat. Cold C to D slow isothermal compression.

Thermodynamics, Heat, Temperature

Heating D to A adiabatic compression from outside work flywheel returns the gas to its initial state A. This same mechanical work is also the area of the corresponding loop in the V-p diagram pressure as a function of volume.

Efficiency of a Heat Engine Carnot was primarily concerned with steam engines and the mechanical power which could be obtained from the fire heating up the hot reservoir the cold reservoir being provided from the surroundings at "no cost", from a water stream or from atmospheric air.

Refrigeration Efficiency The primary purpose of a refrigerator or an air-conditioning unit is to extract heat from the cold source to make it cooler.

Its efficiency is thus usefully defined as the ratio of that heat to the mechanical power used to produce the transfer. So defined, the efficiency of a Carnot engine driven backwards as a refrigerator is: Efficiency of a Heat Pump A heat pump is driven like a refrigeration unit, but its useful output is the heat transferred to the hot side to make it warmer.

For a Carnot engine, this latter efficiency is: Thermodynamics is based on the statement or belief that almost all details about large physical systems are irrelevant or impossible to describe.

Oh! And of course, FREE PRINTABLES!

There would be no point in tracking individual molecules in a bottle of gas, even if this was practical. Only a small number of statistical features are relevant.

A substantial part of thermodynamics need not even be based on statistical physics. Once the interesting quantities are identified, their mutual relations may not be obvious and they repay study The first law of thermodynamics then reads: One example of an extensive quantity is the volume V of a system.

A small change in an extensive quantity entails a proportional change in energy. This is a linear function of modern customary measurements of temperature.

The total change in entropy thus entailed is:The projection of point p onto a line is the point on the line closest to p. (And a perpendicular to the line at the projection will pass through p.)The number t is how far along the line segment from v to w that the projection falls.

So if t is 0 the projection falls right on v; if it's 1, it's on w; if it's , for example, then it's halfway kaja-net.com t is less than 0 or greater than 1 it.

This is an AC electric generator which lights up a tiny incandescent light bulb. The generator is made from a hollow-ended cardboard box with a nail through the center. Game theory is the study of the ways in which interacting choices of economic agents produce outcomes with respect to the preferences (or utilities) of those agents, where the outcomes in question might have been intended by none of the kaja-net.com meaning of this statement will not be clear to the non-expert until each of the italicized words and phrases has been explained and featured in some.

That's at least what we're going to try in these TED Dialogues, starting today.

And we couldn't have anyone with us who I'd be more excited to kick this off. We took a normal TCP socket, injected it with a mix of radioactive isotopes stolen from a secret Soviet atomic research project, bombarded it with era cosmic rays, and put it into the hands of a drug-addled comic book author with a badly-disguised fetish for bulging muscles clad in spandex.

What distinguishes solids, liquids, and gases– the three major states of matter— from each other?Let us begin at the microscopic level, by reviewing what we know about gases, the simplest state in which matter can exist.
