A silver bar with a mass of 250.0 g is heated from 22.0 º C to 68.5 º C. How much heat does the silver bar absorb?

Respuesta :

Heat gained or absorbed in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. The specific heat of silver is 0.233 J/g-C It is expressed as follows:

Heat = mC(T2-T1)
Heat =250(0.233)(68.5 - 22.0)
Heat = 2708.625 J energy absorbed
