Question

How do you find percent change?

Answer 1

See explanation.

Explanation:

I assume you have 2 measurments start - `x_s` and finish - `x_f`.

To calculate the change you use this formula:

`c=|x_f-x_s|/x_sxx100%`

Example:

Let's say that a temperature changed from `300K` to `330K`. To calculate the percent change I use the formula:

`c=|330-300|/300xx100%=30/300xx100%=1/10xx100%=10%`

From these calculations we see that the temperature change (increase) is `10%`
