In calculating the relationship between the amount of heat added to a substance and the corresponding temperature change, the specific heat capacity is usually represented by which symbol? a) cb) qc) δtd) me) none of the above

A

Explanation:

The specific heat capacity can be defined as the amount of energy that is required to raise the temperature of 1kg of a body by exactly 1k.

When calculating the amount of heat required, we usually employ the use of the formula that relates the amount of heat, the mass of the body, the specific heat capacity and the temperature change. The amount of heat is represented by H, the mass of the body by m, the heat capacity by C while the temperature difference is represented by delta T

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
