    Using E=mc^2 does thermal energy add to an object's mass?

    I don't know where you are going with this. The question was does E = mc2 (or E2=c2p2+m2c4 )imply that the mass of an system increases as it gets hotter? Is your answer no to that?

    Using E=mc^2 does thermal energy add to an object's mass?

    I seems that the others on this forum are more knowledgeable than I but my impression is that if E (of the system) increases then, since c is invariant, then p and/or m must go up to balance your equation.

    Using E=mc^2 does thermal energy add to an object's mass?

    Hi everybody, I hope this is the appropriate place to post this question: A middle school physics book here in Sweden poses this question after giving a brief explanation of E = mc2: For you Swedish speakers here is the original text: So my answer is "Yes" to both since the additional...
