Heat+and+Temperature

=Heat and Temperature= Over the years we have learned a great deal about efficient ways of heating our homes and cooking our food. The pan of water that boiled dry over the cookfire has been replaced by a whistling kettle on a gas or electric stove. Even more advanced technology has given us “cordless” electric kettles that shut themselves off when the water they contain reaches boiling point. Many other technologies also use thermal energy to make our lives easier or more comfortable.
