The quantity of heat absorbed by a substance as it increases in temperature depends on which factors?

The quantity of heat absorbed by a substance as it increases in temperature is fundamentally determined by three key factors: the temperature rise, the mass of the substance, and its specific heat capacity.

Firstly, the temperature rise indicates how much the temperature of the substance increases, with a larger temperature increase requiring more heat energy to be absorbed. Secondly, the mass of the substance is crucial because more mass means there are more particles to absorb heat, thus requiring a greater amount of energy for the same temperature rise. Finally, the specific heat capacity is a material-specific property that indicates how much heat is needed to raise the temperature of a unit mass of the material by one degree Celsius. Different materials have different specific heat capacities; for example, water has a higher specific heat than metals, meaning it requires more energy to increase its temperature compared to metals.

Together, these three factors allow for the precise calculation of the heat absorbed using the formula: ( Q = mcΔT ), where ( Q ) is the heat absorbed, ( m ) is the mass, ( c ) is the specific heat capacity, and ( ΔT ) is the change in temperature.

This understanding is essential for various applications in power engineering, including thermodynamics, material
