Heat = m Cp (T2 - T1)

m is mass

Cp is heat capacity

T is starting and ending temperatures

Watch your units, plug in the numbers, and there you have it. Works with anything you have the data for, as long as the substance does not undergo a phase change.

the formula is : Q=M*CP(T2-T1)

where Q=heat in kj

M=mass of carbon power in kg

CP=specific heat of carbon power at constant pressure in kj/kg.k

T2=final temperature in digree kilvin

T1=starting temperature in digree kilvin

HENCE YOU GET WHAT YOU WANT , WITH BEST REGARDS
