T(F) = 9/5T(C) + 32 Equation for Temperature in general

Change in Farenheit Formula

Change in T(F) = 9/5change in T(C) Temperature in relation to change

Change in Kevin Formula

Change in T(K) = change in T(C) If temperature in celsius increases by one degree, temperature of kelvin will increase by the same amount. The 273.15 CANCELS OUT.

Linear Expansion Formula

Change in L = initial L * a * change in T

Lo + change in L. Furthermore, Tf = To + change in T.

If a substance has a larger coefficient of expansion, it expands faster & contracts faster. When heated an object bends towards steel, expansion for brass is larger meaning it has a bigger coefficient. Cooled, opp, brass contracts & bends towards it.

Expansion of Holes Example

Tiles are arranged in square pattern; when tiles are heated, pattern is too and hole in the center expands. The expanded hole is the SAME SIZE as a heated tile.

Tip About Objects Fitting

If you're trying to fit one object through the other, you have to match the diameter of the two objects. This is best done by heating up the steel ring, though you can also cool the sphere.

Volume Expansion Equation

Change in V = Vo*B*change in T The units used are celsius^-1

If you're using a cooler and reservoir, the min setting refers to the minimum amount of fluid you need to cool the engine. The max means the max amount you can use to still have room for expansion without damage to the engine.

The energy required to change the temperature of a unit mass of a substance by 1 degree. You can apply this relationship while the object is in a liquid or solid phase, but once the phase changes, you have to use something else.

Latent Heat of Fusion

Q = mass * Lf Change from solid to liquid and vice versa. Happens when temperature is fixed -- not temperature dependent!

Latent Heat of Vaporization

Q = mass * Lv Change of mass from liquid to gas and vice versa.

If you are trying to find the total heat expansion...

You're going to use the regular change in L equation, then multiply that by how many squares there are. Then, if it's asking for the minimum gap length to prevent buckling/etc, divide that amount by the number of gaps.
