    As the others have pointed out it means a change.

    So the energy to raise it from 100 to 101.43 degrees is the same as to raise it from 20 to 21.43 degrees.  Wherever delta is seen you can substitute it with (T2-T1) or similar to find the final absolute result.

    As Lee pointed out, the triangle is an uppercase Greek letter delta, it means change. So in this equation, adding 600J of energy to your system increases the temperature (avg Kinetic Energy) by 1.43 degrees Celsius

    Delta, it’s a difference in temperature, temperature change.
