Question
a- Calculate the quantity of heat necessary for this transformation?
b- If this heat is provided by the combustion of coal, calculate the mass of coal used?
Solution
To provide a precise solution to your questions, I need some additional details regarding the transformation and the specific properties of the coal. Please specify the following:
- What type of transformation are you referring to (e.g., melting, boiling, chemical reaction)?
- What is the mass of the substance undergoing this transformation, as well as its specific heat capacity or heat of transformation?
- What is the heat of combustion of the coal (in kJ/kg or similar units)?
Once I have this information, I can break down the problem, perform relevant calculations, and give you a complete answer.
