FAQs on NCERT Solutions for Class 7 Science Chapter 4 - Heat
1. What is the name of Chapter 4 of Class 7th Science?
The name of Chapter 4 of Class 7th Science is ‘Heat’. This chapter will stress upon and discuss in detail how the transfer of energy occurs and its significance. The solutions for this particular chapter can easily be found on the Vedantu site along with additional help required by the student for achieving good marks in their exams. The solutions provided by Vedantu are free of cost and also available on Vedantu Mobile app.
2. What is heat according to Chapter 4 of Class 7 Science?
Heat in simple terms is nothing but the transfer of energy. It helps in maintaining thermal equilibrium, i.e. for having the same temperature when multiple bodies with their different individual temperatures are in contact. Hence for all of them to have the same temperature, energy transfer occurs from the bodies which have the higher temperature to the ones whose temperature is lower. Heat transfer and its processes are very crucial and hence learn the concepts and practice the related problems judiciously.
3. What is a thermometer according to Chapter 4 of Class 7 Science?
A thermometer is a temperature-measuring instrument. It is capable of determining the temperature of a variety of substances, including food, liquids, and gases. Celsius, Fahrenheit, and Kelvin are the three most widely used temperature measuring units in the world. The most accurate technique to check one's body temperature is with a digital thermometer. In addition to the traditional oral, rectal, and forehead, there are also plenty of other options.
4. What do you mean by conductors according to Chapter 4 of Class 7 Science?
The transmission of internal energy via tiny particle collisions and electron movement within a body is known as thermal conduction and the materials that exhibit this propagation are called conductors of heat. Good heat conductors are materials that allow heat to readily flow through them. Metals that exhibit the highest thermal conductivity include copper and aluminium, whereas steel and bronze exhibit the lowest values.
5. What do you mean by insulators according to Chapter 4 of Class 7 Science?
An insulator is a substance that prevents energy from easily passing through it, such as electricity, heat, or cold. Insulators such as wood, plastic, rubber, and glass are effective. The conductor is the polar opposite of an insulator: a substance that easily conducts heat or electricity. Insulators shield humans from the potentially lethal consequences of electricity passing via conductors. An electrical circuit's voltage can be extremely high and harmful at times.
