Have you ever observed what happens when a hot cup of milk is left on the table? After some time, it cools down and reaches room temperature or the temperature of its external surroundings. This happens due to the heat exchange between the surroundings and the cup of milk. If we plot a graph of […]

Let us leave a cup of hot water on the table. After some time, the water will start to cool, and finally, its temperature will reach the temperature of the surroundings. We all know that temperature is a measure of the degree of hotness or coldness of a body. Temperature is a sensory perception and

Heat is a type of energy that starts at the molecular level and works its way up. When power is added to a substance, the molecules of that substance move in one direction or another. While molecules start vibrating upon being heated, they pass on the heat to their surrounding molecules, making them vibrate as

Introduction  In this article, we will be focusing on the concept of latent heat. We will discuss latent heat of fusion and latent heat of vapourization with the help of solved examples and much more. The form of energy transferred between two materials having different temperatures is called heat.  Latent heat  When a substance undergoes

Iso stands for constant and thermal stands for temperature. Isothermal processes are the processes in which the temperature is constant. Expansion takes place when the volume of the system increases or when pressure decreases. Isothermal expansion is the process of expansion in which the temperature is constant. The process maintains thermal equilibrium. What is Isothermal

We know that integration is an important part of calculations, and it is done using various methods. Of all the methods used for integration, integration by a partial fraction is one of the methods. In this, the complex rational fractions are converted into partial fractions, which are in the simpler form using the formulas for

Hurricanes arise when a cluster of tropical thunderstorms forms a low-pressure system with winds blowing in from the surrounding locations. The Coriolis force, a “fictitious” force caused by the Earth’s rotation, bends these winds into a rotating system that rotates counterclockwise in the northern hemisphere and clockwise in the southern. Hurricanes acquire their energy from

HEAT WORK AND INTERNAL ENERGY The form of energy that transfers from one system to another is called heat, and it does not depend on the system. But if the energy depends upon the system, it is termed internal energy. All heat work and internal energy are interrelated. Let us see in detail. WHAT IS

Heat transfer is one of the subjects in thermal engineering, which is primarily concerned with the exchange, use, and conversion of heat or, in other words, thermal energy between physical bodies. Exchange of thermal energy due to the difference in temperatures. This heat transfer takes place when there is a temperature difference. Let’s discuss this
