A 4.0 kg copper skillet must be heated from room temperature (23.0 C) to a temperature of 130.0 degrees Celsius. If the specific heat of copper is 0.3851 J/g. Degrees Celsius, how many Joules of heat are required?

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
