Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.
Question
Two objects of differing temperatures are held so that they are in thermal contact with each other. Which situation best describes the scenario?
Transcribed Image Text:### Question on Thermal Conduct
**Question:**
Two objects of differing temperatures are held so that they are in thermal contact with each other. Which situation best describes the scenario?
**Answer Choices:**
1. **hot object transfers heat to cold object/cold object heats up/heat transferred via convection**
2. **hot object transfers heat to cold object/cold object cools down/heat transferred via conduction**
3. **hot object transfers heat to cold object/cold object heats up/heat transferred via conduction**
4. **cold object transfers heat to hot object/cold object heats up/heat transferred via conduction**
**Explanation:**
This question is focusing on the transfer of heat between two objects at different temperatures. The key concepts here are conduction and convection. In the context provided:
- **Convection** typically refers to the heat transfer in fluids (gases or liquids), where warmer areas of a liquid or gas move to cooler areas.
- **Conduction** refers to the heat transfer through direct contact between solid objects, where heat moves from the warmer object to the cooler one.
Analyzing each answer choice:
- **Choice 1** is incorrect because it describes heat transfer via convection, which is not applicable to solid objects in direct thermal contact.
- **Choice 2** is partially correct, but it incorrectly states that the cold object cools down.
- **Choice 3** is correct because it accurately describes that the heat from the hot object transfers to the cold object, causing the cold object to heat up, and the mechanism of transfer is conduction.
- **Choice 4** is incorrect because it suggests that the cold object transfers heat to the hot object, which contradicts the natural flow of heat energy (from hot to cold).
Therefore, the correct answer is:
3. **hot object transfers heat to cold object/cold object heats up/heat transferred via conduction**

Note: This question involves understanding the basic principles of heat transfer, an essential topic in physics and thermodynamics related to temperature change and energy flow.
