Such effects of heat on substances will be discussed in this chapter. Because all of the many forms of energy, including heat, can be converted into work, amounts of energy are expressed in units of work, such as joules, foot-pounds, kilowatt-hours, or calories.Exact relationships exist between the amounts of heat added to or removed from a body and the magnitude of the effects on the state of the body. The effects of heat energy are the following: (i) When heat is supplied to a body its temperature rises: When a material body, solid, liquid or gas, is given heat energy, its temperature increases. Conduction: The process of flow of heat from a hot object to a cold object is called Conduction. Electric Energy is product of Electric Power and Time, Electric Power is measured in Watt and Time in Second, So Electrical Energy-Watt × Hours = Watt Second, When an electric current passes through a conductor (like a high resistance wire), the conductor becomes hot after some time and produces heat, This is called heating effect of Electric Current, A bulb becomes hot after its use for some time.This is because of heating effect of electric current, When we switch on an electric iron,it becomes hot.This is also because of heating effect of electric current, Heating Effect happens due to conversion of electric energy into heat energy, We know that battery or cell is a source of electrical energy, Due to chemical reaction in this battery or cell,potential difference is generated, This potential difference causes electrons to flow through circuit, This circuit has resistors which resist flow of current, Work is to be done to overcome this resistance, This source energy in conductor is dissipated(converted) in resistor as heat energy, It is because electric iron has a heating element like high resistance wire which help in converting most of electric energy into heat energy, We know that as per Joule's Law of Heating, Heat is Directly Proportional to Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. The builder of the website is Mr. Md. So, in this heat may change the state of the body like ice can also get change into the water. H = VIt Follow the precise instructions in Heat and Its Effects Class 7 Notes. For example, on heating, ice(solid), eventually changes into water (liquid). Temperature is an indicator to indicate the direction at which heat energy will flow. Application or removal of heat transforms a substance from one state to another. The physics is one of the oldest academic disciplines, perhaps the oldest through the inclusion of astronomy. It means if we use a wire made of metal having more resistance (like nichrome wire),it will resist the flow of current and hence it will produce more heat. Other possible effects include large-scale changes in ocean circulation. Teachoo provides the best content available! (c) 60 J Heat transfer is a part of thermal engineering that deals with the generation, use, conversion, and exchange of thermal energy between physical systems.
