Concept explainers

Thermochemistry

Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.

Exergonic Reaction

The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.

Question

The problem states:

"The temperature of an object increases by 24.4 °C when it absorbs 3725 J of heat. Calculate the heat capacity of the object."

A box is shown for entering the value of heat capacity (C) in J/°C. An incorrect answer, "6.2567," is entered.

Below, more information is provided:

"The mass of the object is 397 g. Use the table of specific heat values to identify the composition of the object."

A table is provided with the specific heat values of various substances:

| Substance | Specific heat (J/(g·°C)) |
|-----------|--------------------------|
| Gold | 0.129 |
| Copper | 0.385 |
| Iron | 0.444 |
| Aluminum | 0.900 |

A multiple-choice question follows:

"The object is composed of"
- Gold
- Copper (selected)
- Iron
- Aluminum

The aim is to calculate the specific heat capacity using the formula \( q = mc\Delta T \) and use the result to match the specific heat value to one of the substances listed.
