Physics Class 10 Chapter 11 Notes: FBISE PDF
In Physics, understanding thermal transformations is essential to learn how energy moves from one object to another. This Chapter 11 explains the fundamental difference between heat and temperature, and how substances react when they absorb thermal energy. Concepts like specific heat capacity and latent heat are very important for students to solve numerical problems easily. If you want to study from the most reliable sources, you can find the best AiNotes.Pk for all subjects.

Frequently Asked Questions (FAQs)
Q1: What is the main difference between heat and temperature? Ans: Heat is the total internal energy of an object due to molecular motion, while temperature is the measure of the average kinetic energy of the molecules in that object.
Q2: What is meant by Specific Heat Capacity? Ans: Specific heat capacity is the amount of heat energy required to raise the temperature of 1 kg of a substance by 1 degree Celsius (or 1 Kelvin).
Q3: How does thermal expansion occur in solids? Ans: When a solid is heated, its molecules vibrate more vigorously, pushing each other further apart. This causes the overall volume or length of the solid to increase.
Q4: What is the difference between evaporation and boiling? Ans: Evaporation happens only at the surface of a liquid and at any temperature, while boiling occurs throughout the liquid at a specific fixed temperature called the boiling point.
Q5: What is Latent Heat of Fusion? Ans: It is the amount of heat energy required to change a unit mass of a substance from solid to liquid state without any change in its temperature.
