I read that if the temperature of 1 Kg of gold rises by 10°C its mass increases by 1.4 * 10^-14 kg.
Can you please explain how you get such value from E= mc^2?
I think the increase corresponds to E = h f =1.53*10*10^36 and since
1 kg has 1.1*10^30 electrons, each one gets 1.4*10*6 h
but
10 degrees correspond to energy E = h f = 2.8*10^11 h)
so shouldn't the increase of energy be 2.29*10 ^41 h?
Can you also tell what instrument can measure the weight o 10^-14 Kg and what is the minimal weight that can be detected?
