Question:

How much heat energy is needed to raise the temperature of a 56 g sample of aluminum from 27?C to 99.8?C?

The specific heat ofaluminum is 0.897 J/g · KAnswer in units of J.

Answer:

Since there is no change in the state of Aluminum, we have the heat needed ( say Q J ) to heat 56 g of Al from 27 C to 99.8 C- Q mass of Al x specific heat capacity of AL x rise in temperature of the sample Q 56 x 0.897 x ( 99.8 - 27 ) J Q 3656.8896 J Answer Answer Which may be round up to 3656.9 J .
