Percentage Error from equiptment used.

*An error is half the smallest possible reading.*

The errors can come from:

• Thermometer: reads to nearest degree celcius, half = +/- 0.5 degrees celcius error.
  
• Balance: Reads to two decimal places, so the error is half of 0.01, therefore, +/-0.005g

Working out errors:
Balance error- We weighed on the balance twice, therefore, times eror by two = 0.01, then:
0.01/mass weighed (calculated). You then multiply this by 100 to get the percentage error.

So:

1. Multiply error by how many times used. (I.e., two readings = multiply by two.)
2. Divide this by the mass weighed, which you should have calculated.
   
3. Multiply by 100 to reach the % error. (:
   

Thermometer Error-

1. Times the error by how many times used read off the thermometer. (So, two, would be 0.5 x 2 = 1) :D
   
2. Then you divide this by the difference in tempereature, which you should have calculated, or been given.
   
3. Multiply by 100 to get the % error.
