Is peanut butter and red food coloring a chemical change or a physical change?

Peanut butter and red food coloring is a [physical change]. A chemical change is something that changes the properties of the original substance. Chemical changes are usually irreversible and result in a newly formed substance. Examples of chemical changes are the formation of rust and when you are cooking something (such as eggs). Peanut butter and red food coloring does not describe a process, only saying that you have two completely different items. For this reason, I will have to go with physical change. Nothing is newly formed between the two, and they are not being combined together in a form of cooking or another chemical process. Even if the red food coloring was added to the peanut butter, this would still be a physical change because you are only adding something that is harmless or unchanging onto a completely neutral substance, peanut butter. Adding red food coloring normally to the peanut butter is only a physical change because nothing is newly formed or being changed.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
