An easy way to visualize work as an energy transfer is to imagine pistons that move when a force is exerted on them. Hess's Law: When there are two or more balanced chemical equations to show the steps of a reaction, the change in enthalpy for the net equation is the sum of the ...

In equations that contain a mixture of logarithms and other algebraic terms, it's important to collect all the logarithms on one side of the equation. You can then add or subtract terms. According to the law of logarithms, the following is true: logx+logy=log(xy)logx–lo...
Given the following equations, determine the values of x and y. \\ x^2 + y^2 = 9\\ x + 2y = 1 Rearrange the expression 0.20 = x^2/(25 - x) into the quadratic form ax^2 + bx + c = 0 where a = 1, and identify the values of b and c. In the equation V=sqrt(rg),...
To solve for Hvap, we can rearrange the equation to isolate for Hvap: Hvap = -R*(slope)*(1/T) + C Where R is the gas constant and C is the y-intercept of the graph. To find the heat of vaporization, we need to plug in the values for slope, temperature, and ...
Involving quantum equations. All of thy geometry, Herr Planck, is fairly hard. — Anonymous extension to Sir Jeans’ famous mnemonic above. 3.14159 26535 89793 23846 26433 8 For circumscribing a round enclosure or circle, every man might remember ingenious numbers measuring one by one ...
It must include a sliding ladder to reach the highest shelves. For many, an open floor plan is non-negotiable. Whatever it is, write it down. You will want two lists: essentials and non-essentials. Then, rearrange them and put them in order of importance. It might surprise you how many...
Rather than producing light, LCDs rearrange light molecules to create a pattern on the display and ultimately don't require as much electricity. Early calculators also had to be plugged in or used bulky battery power. But by the late 1970s, solar cell technology had become cheap and efficient...
If you are the sort of person who finds equations memorable, they are a good way to bring together small, non-word atoms with entropy from the top line of the keyboard. For example du=Tds+(P/rho^2)drho U+2ClF3->UF6+Cl2 and so on. There are tons from physics, math, chemistry, ...
