Practical Applications of Joule's Heating
Practical Applications of Joule's Heating - This heating is inevitable in any electrical circuit. Since the energy lost by the flowing charges ends up as disorderly thermal motion, the phrase 'ohmic dissipation' is also used to describe it. Often, this is an undesirabl..
Action of Heat on Sulphur
As the temperature increases, the octa-atomic ring breaks, and forms a long chain of eight atoms (Fig.13.26). The color gradually darkens form pale yellow to amber color. As more and more molecules become long chain molecules, the chains get entangled. Hence the liquid becomes less mobile..

Heating Effects: Joule's Law - When a potential difference is applied across the ends of a conductor, the free electrons are accelerated and acquire kinetic energy. As the electrons move through, they collide with the positive ions and atoms of the conductor and transfer their kinetic ene..
Change in Temperature
We have already observed that when a substance is heated, the very first effect we observe is that its temperature rises. Similarly when a substance is cooled (i.e. heat energy is removed from the substance) the temperature of a substance decreas..

Heat is a form of energy. Heat energy is also called thermal energy. When heat is given to a body, its temperature increases and when heat is removed from a body, its temperature decrease..

Heat Capacity
Heat capacity gives a measure of the quantity of heat absorbed by a system. It is defined as the amount of heat required to rise the temperature of the system through 1 o C. If the quantity of heat required is to raise the temperature of u..

Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
Good teaching skills, an amazing tutoring, would recommend it to everyone - Maadai
Great sessions, learned a lot and got lots in and techniqul problem systm is showing me out of the session when i am not ,This is Awesome - Haley
