Thermodynamics, Laws of Thermodynamics,Concepts in Thermodynamics

  Thermodynamics is a branch of physics that deals with the study of energy, work, heat, and their relationship to properties of matter. It has several laws and principles that govern the behavior of energy and its transformation. Here's an overview: Laws of Thermodynamics : Zeroth Law of Thermodynamics: If two systems are each in thermal equilibrium with a third system, they are in thermal equilibrium with each other. This law introduces the concept of temperature and the transitive property of thermal equilibrium. First Law of Thermodynamics (Law of Energy Conservation): It states that energy cannot be created or destroyed in an isolated system. It can only be transformed from one form to another or transferred between systems as heat or work. The mathematical representation is often given as ΔU = Q - W, where ΔU is the change in internal energy, Q is heat added to the system, and W is work done by the system. Second Law of Thermodynamics : There are several formulations of th

Survey on E Rikshaw(Electric rikshaw) in comparison to Auto Rikshaw

With the coming up of battery rickshaws in Delhi, the income of auto rickshaw drivers has been badly affected. To figure out whether it is true or not, you decided to do a survey amongst the auto rickshaw drivers of Delhi. Conducting a survey among auto rickshaw drivers in Delhi is a great way to assess the impact of battery rickshaws on their income. You can create a questionnaire with questions related to their income, the competition from battery rickshaws, and any changes they've observed in their business. This data can help you determine the extent of the impact and whether their income has indeed been affected.  With the coming up of battery rickshaws in Delhi, the income of auto rickshaw drivers has been badly affected.
