Consider a piece of metal that is at 5 deg C. If it is heated until it has twice the internal energy, its temperature will be.

a)556 deg C
b)283 deg C
c)273 deg C
d)278 deg C
e)10 deg C

• Physics -

Thermal E~kT, where k is the Boltzmann constant, T is the temperature in Kelvins
5℃=278K
Answ. 278 x 2=556 K

• Physics -

Would the answer be B because the temperatures are denoted in deg C? 556K - 273 = 283 deg C.
