how much energy is needed to raise the temperature of a silver necklace chain with a mass of 22.5 g from room temperature, 25 degrees celsius to a body temperature of 37 degrees celsius

Question

We need to know one piece of information:  the specific heat of Silver metal.  This is the amount of energy to raise the temperature of 1 gram of material by 1 Celsius degree.
  $ \dfrac{\text{J}}{\text{g $\cdot$ C$ ^o$}} $
Notice that by observing these units, we simply have to multiply specific heat by the change in temperature and the mass:
  $ \text{Energy} = m \times \Delta T \times C $ 
The end unit will be in Joules, the unit of energy!
