Heat Class 7 Science Notes – Chapter 4
Have you ever experienced feeling cold inside the house and warm in sun during winter? Also, feeling hot inside as well as outside the house in the summer season? To protect ourselves from the chilling cold we wear clothes made of wool. These woolen clothes are obtained from wool yielding animals such as sheep, goat, yack, etc. Wearing light colored clothes during summer will give us a feeling of coolness. To know if the object is hot or cold, and the degree of its hotness, we will be studying this chapter. The measure of the intensity of heat present in a substance is called temperature. It is measured with the use of a device called thermometer. Please refer Heat Class 7 Notes for more revision notes.
