| Video Discription | #Heat #energy Heat is a form of energy. Sun is the vast source of heat energy. When we are exposed to sunlight we can feel the heat. In the winter when we rub our hand mechanical energy converts in to the heat energy. There are various sources of heat. Energy is capacity to to work. Many people don't know that heat is also a form of energy only. Heat flows from higher temperature to lower temperature. When we heat water its energy in the form of heat increases then it becomes hot. When the heat energy of the body increases then it can change the temperature of body, there can be change in the dimensions of the body hence size of the body changes and the state of the body can also change. In this video the answer you can get is 'what is heat' We can feel the heat but we can not see it. Plants use the heat of the sun to prepare their food bye photosynthesis On burning coal or cooking gas, heat can be generated. SI unit of heat is joule. Other units are calorie and kilocalorie. Heat required to raise the temperature of 1g of water by 1 degree is 1 calorie. Temperature measures degree of hotness and coldness of an object. Because we can only feel energy and we can't tell how much hot or cold a body is. There are three units of temperature. Celsius Fahrenheit and kelvin. °C is Celsius. °F is Fahrenheit. K is Kelvin. Kelvin is not written as °K. Its simply written as K . Kelvin is absolute scale.

You will get the knowledge about the temperature scales i.e. Celsius Fahrenheit Kelvin. You will know the units of heat. you can follow us on Instagram @ms inception and on Facebook ms inception FmdwD9613Dw |
