Class 11

The Rutherford model states that when a high energy Alpha particle is passed through a thin gold foil (100 nm thickness) by placing a fluorescent zinc sulphide screen around the foil, then most of the particles pass through the thin foil undeflected, while some of the particles are deflected by a small angle. However, very few particles bounced back, that is, were deflected by nearly 180°. 

The syllabus of CBSE class 12th and CUET is same. Mostly class 12th syllabus question will asked in CUET. But for concept you must have knowledge of class 11th. For CUET follow NCERT syllabus of class 12th.

The structure of an atom in chemistry class 11 is a particle (nucleus) that is surrounded by positively charged protons, electrons (negative charge), and neutrons (no charge). The negatively charged electrons orbit around the nucleus.

Class 10th and class 12th previous years question paper are easily available on internet but class 11th does not contain pyqs. You can get important question answer from imternet, but pyqs are only obtained from your school

In the Carnot engine, the maximum possible efficiency operates between two temperatures. It is an ideal heat engine. The efficiency of the Carnot engine only depends on the temperatures of the heat source including T1 and T2. These temperatures should be in Kelvin. No real engine can exceed the efficiency of the Carnot engine.

Internal energy is the total potential energy (from intermolecular forces) and kinetic energy (from particle motion) within a system due to the motion and interactions of its particles. In simple terms, it is the total energy in a system. Internal energy changes when heat is added or removed or when the system performs some work.

Thermodynamics is a part of physics that deals with the relationship between temperature, heat, energy and work. The Thermodynamics concept explains how energy is transferred in physical systems and how it affects matter. The laws of thermodynamics help in understanding phenomena like refrigerators, engines and even biological processes and govern these changes.
