Question

does the temprature affect weight​

Answer 1

Answer:

The reason why hot objects are heavier is because E=mc^2. If you have absolutely identical objects that have the same weight exactly when they are at same temperature, then when one object is heated, it will weigh more. This is because the gravitational force depends on the stress energy tensor in general relativity

Answer 2

Answer:

So when the particles of the heated object gain energy after absorbing external photons, its kinetic energy increases. That increase in kinetic energy provides an increase in weight
