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

**Title: Identifying Cooling Points on a Heat Energy Diagram**

**Overview:**
This resource guides you through identifying points on a heat energy diagram where the removal of heat causes a decrease in temperature. Understanding these points is crucial for comprehending phase changes and thermal dynamics in a sample.

**Task:**
Identify the point(s) where the removal of heat will cause the temperature of the sample to decrease.

**Diagram Explanation:**

- **Axes:**
- The x-axis represents Heat Energy.
- The y-axis represents Temperature.

- **Plot:**
- The diagram features a series of points labeled A, B, C, D, E, F, G, H, J.
- The plot consists of horizontal and inclined lines connecting these points.

- **Line Segments:**
- Horizontal segments (e.g., B to C, F to G) typically indicate phase changes where temperature remains constant despite heat removal or addition.
- Inclined segments (e.g., A to B, C to D, E to F, G to H, H to J) suggest regions where temperature changes with heat removal or addition.

**Instructions:**
Enter the points in alphabetical order where the removal of heat will lead to a temperature decrease (e.g., DFJ, not FDJ). This often occurs along inclined segments.

- **Points to Consider:**
- Points linked by inclined lines are indicative of temperature changes due to heat removal.

**Submission:**
- Place your answers in the 'Point(s)' text box and click "Submit Answer."
- You have 3 attempts to correctly identify these points.

This exercise is integral for students to understand heat exchange principles within a given sample, reinforcing the theoretical knowledge with practical application.
