Hi

 

why in this question we did not convert the unit of temperature to kelvin ?

 

Aluminum has A specific heat of 0.902 J/gm C . How much heat is lost when a piece of aluminum with a mass of 23.984 gm cools from a temperature of 415.0 C to a temperature of 22.0 ?

 

the answer is :

Q = m Cp X delta T

 

=23.984 X 0.902 X 22 - 415

= -8500 J

What is the relationship between ºC and K?

 

And what happens with that relationship when you take a temperature difference (delta T)?

thanks I got it .
