What error is introduced in a mass determination if the object being weighed is warm? Why?

THANK YOU!

Mass is independent of temperature.

But you asked about measurement... if you're using a triple beam balance, the warm mass would heat the air around it and could actually appear to weigh less. This is a stretch - that'd have to be a pretty accurate balance, and some seriously warm mass.

Heat affects density for a lot of substances. Hot air is less dense than cold air. Hot water is less dense than cold water, etc.

I should have added that density and mass are NOT the same thing.

mass is an intrinsic property of matter how much thermal energy it possesses is irrelevant. I think you may need to rephrase your question
