*Wrong. Simply raising the the temperature of an object does not raise the mass. What are you guys smoking?*

We're smoking Einstein's old pajama pants. Also, we're correct and you aren't. Higher temperature means more energy in a system. More energy means more mass. Yeah, it's a little weird. It's also an inevitable consequence of the constant speed of light, and the conservation of momentum and energy. Starting with those three assumptions you can prove that E=mc^2.

To do the math:

1 kg of Carbon Steel raised 1 degree Kelvin will gain 5.45e-9 grams

Specific heat of Carbon Steel = 490 J/(g*K)

Energy required to raise 1 kg 1 degree K = 490*g*K = 490*1000*1 = 490000 joules (kg*m^2/s^2)

mass of 490000 joules = m = E/c^2 = 490000 kg*m^2/s^2
