If you cut the cube and keep all the pieces you are causing only physical change
A source of error is any factor that may affect the outcome of an experiment. There are countless conceivable sources of error in any experiment; you want to focus on the factors that matter most. Identify each source of error specifically and then explain how that source of error would have affected the results. Keep in mind that an "error" to a scientist does not mean "mistake"; it more closely means "uncertainty".
Many students are tempted to say "human error", but this term is vague and lazy; any decent teacher will not accept it. Instead, think about specific things that happened during the lab exercise where the end results may have been affected.
To give an example one might find in a bio lab: perhaps a water bath's temperature was not monitored very carefully and you found that an enzyme's activity was greater than you expected. In that case, you could write something like,
"The temperature of the water bath during this exercise was not monitored carefully. It is possible that it was warmer or cooler than intended, and this would have affected the enzyme activity accordingly. The fact that our enzyme activity was found to be higher than expected leads me to believe that perhaps the water bath was too warm."

Brass is an alloy of copper and zinc and is durable, malleable and sonorous.
<h3>
What are alloys?</h3>
Alloys are products which are obtained from a mixture of two or more metallic elements.
Alloys are preferred to the individual elements because they combine the desirable properties of their component elements.
An example of an alloy is brass.
Brass is mixture of copper and zinc. It combines the shiny and anti-rust properties of zinc with the durability and sonorous property of copper.
It very sonorous and malleable and is used in many musical instruments.
In conclusion, alloys are produced by mixing two or more metals together.
