    Graduate Variation of energy but constant entropy

    Hello; If a system receives a thermal energy Q, can it keep its entropy constant (that is, with equal value before it receives the energy) without wasting the energy received?

    Graduate Explaining Temperature Increase with Antenna and Tissue

    The power output of the antenna is the same, but the absortion of the tissue is different, and there is no way that the temperature increase can only be related to tissue. Anyway, thaanks!

    Graduate Explaining Temperature Increase with Antenna and Tissue

    Hi; Let's imagine that I have an antenna and a biological tissue. The antenna emits the frequency of 1e7 Hz and I have a temperature increase x. When the antenna emits the frequency of 3e7 and 6e7 Hz the temperature increase is the same. How can I explain?
