I need one factor that may cause the density of an object to change. I have a test tomarrow and i have no clue!! help!!

since D=M/ V
if the mass(composition) of the obj changes or the volume changes then the Desity would be different

Temperature and pressure are great answers, but which is more important depends on the system you are describing. For water, for example, pressure plays almost no role in the density since it incompressble (practically), so temperature is the main player. An ideal gas, on the other hand, has an equal importance for temperature and pressure
density = Pressure / (Temperature * Gas Constant)

Temperature is definitely an answer. Molecules slow down as the object gets colder. Think of water, ice, and steam. Good luck.

If butter is heated its density changes, right?

Temperature or pressure.

I am guessing here- but logically it seems temperature might be a good answer.
