The Selina Concise Physics Class 9 ICSE Solutions for Chapter 6 - Heat and Energy includes detailed explanation about the various concepts revolving around ‘heat’, its definition, examples, units along with an understanding of differences between the concepts of heat and temperature as they are often misinterpreted. Additionally, these solutions also explain the behaviour of water at different temperatures, energy sources, and different types of energy sources along with examples.

In the 6th chapter of ICSE Physics Class 9, Heat and Energy is to be covered in the class as per the board guidelines. The heat and Energy chapter deals with an intricate description of numerous perceptions under heat and energy. We know that heat is a modified unit or form of energy. The textbook is best for students who love to understand the theory and concept of temperature, its unit and thermal expansion. All of them are explained with suitable graphs and examples.

When water is cooled from 4-degree Celsius to 0-degree Celcius, we call it an expansion of water. Uncharacteristic expansion of the water unit is mentioned as Celsius.

We will also discuss energy and the flow of energy in an ecosystem. This topic also gives some knowledge about the food chain. Finally, the last sub-topic of this chapter will teach students about the energy sources and the different types of energy.

Physics Class 9 Heat and Energy Example

Explain the change in volume perceived when a specified mass of water is heated from 0°C to 10°C. Also, draw a graph of temperature-volume to demonstrate the behaviour.

Ans: The volume change can be said alternatively that it decreases (contracts) when a specified mass of water is boiled from 0°C to 4°C. An increase in the volume can be seen when it is boiled from 4°C to 10°C. We can say that the volume expands.

The temperature-volume graph given below shows the behaviour.

FAQs on Concise Physics Class 9 ICSE Solutions for Chapter 6 - Heat and Energy

1. What is the SI Unit of Heat? Define its relation with the unit Calorie.

Joule (J) is the S.I. unit of heat. The unit of heat (Joule) has a relation with the unit calorie in the following way:

1 J = 0.24 calorie (nearly).

According to the International system of units (SI), Heat energy is measured in Joules(J).

1 Joule is defined as the amount of energy exerted or work done when a force of one newton is applied over one meter distance.

‘Heat energy’ is defined as a form of energy that flows from a body at a higher temperature to a body at a comparatively low temperature. At atomic levels it is seen in the form of vibrations and it is normally called ‘Thermal Energy’. The atoms vibrating with a higher speed have more thermal energy than the ones with slower vibrations. In thermodynamics, we can say that thermal energy transfers from a hot body to a cold body by means of Kinetic energy.
