How much heat will be absorbed by a 55.5 g piece of aluminum (specific heat 0.930 j/g.°c) as it changes temperature from 23.0°c to 67.0°c? kj

The amount of heat absorbed by aluminium is 2.271 kJ.

Explanation:

To calculate the amount of heat absorbed or released, we use the equation:

Q = heat absorbed  = ?

m = mass of aluminium = 55.5 g

c = specific heat capacity of aluminium = 0.930 J/g ° C      

Putting values in above equation, we get:

Q = 2271.06 Joules

Converting this into kilo joules, we use the conversion factor:

1 kJ = 1000 J

So, 2271.06 J will be equal to 2.271 kJ

Hence, the amount of heat absorbed by aluminium is 2.271 kJ.
