Help needed on mass-energy equivalence

[Abivarman]

TL;DR Summary: problem help pls :(

so i have a presentation competition on physics. and I chose the energy mass equivalency topic. while researching, I came across a video stating that if we compress a spring, it's energy increases, so it's mass also increases. same thing with a cup of coffee. If we heat it, the cup of coffee will have more mass. My question is, is it actually true? Are there any experiments that have proven it? Can you explain to me why this is the case? (also provide me with links.)

Are you asking us to do the research for you?

I would take the view that such statements are sort of true. If you heat a cup of coffee, perhaps some of the liquid evaporates? The extra mass from heating the coffee may not be the most significant change when it's heated. Then you have to specify not a cup of coffee, but coffee inside a sealed container. And, even then, it's an insignificant extra mass that would be impossible to measure.

You are better off looking at cases where the energy is significant. Consider a hydrogen atom, where the mass of the atom is less than the mass of its particles: one proton and one electron. There the mass difference is significant, measurable and confirmed by experiment.

can you give me the link to that experiments, please?

yes :)

Then please pick a topic on which you have some understanding and on which you have done preliminary research that you know you can investigate and can handle. We are here to answer specific questions and clarify misconceptions stemming from what you have discovered. We are not here to do the work for you.
