Calculate KB for water latent heat of vaporization for water is 540 cal per gram |
|
Answer» Solution verified Verified by Toppr Correct OPTION is A 26 cal.K −1 mol −1
Solution:- (A) 26cal/mol−K As we KNOW that, ΔS= T ΔH
ΔH=540cal/g Mol. wt. of water =18g ΔH (PER mole) =ΔH (per gm) ×Mol. wt. ΔH (per mole) =540×18=9720cal/mol Now, as we know that, ΔS= T ΔH
GIVEN T=100℃=(273+100)=373K ∴ΔS= 373 9720 =26cal/(mol.K) PLEASE MARK ME AS BRAINLISTS |

|
Answer» Answer: plz mark me branlist Explanation: The first law of THERMODYNAMICS STATES that energy can neither be created nor destroyed, only altered in form. For any system, energy transfer is ASSOCIATED with mass crossing the CONTROL boundary, external work, or heat transfer across the boundary. These produce a change of stored energy WITHIN the control volume. |

What is the use of electronic components |
|
Answer» ELECTRONIC gadgets have become an integral part of our lives. They have made our lives more comfortable and convenient. From aviation to medical and healthcare industries, electronic gadgets have a wide range of applications in the modern world. In fact, the electronics revolution and the computer revolution go hand in hand. Most gadgets have tiny electronic circuits that can control machines and process information. Simply put, electronic circuits are the lifelines of various electrical appliances. This guide explains in detail about common electronic components used in electronic circuits and how they work. In this article I will provide an overview on electronic circuits. Then I will provide more information on 7 different types of components. For each type I'll discuss the composition, how it works, and the function & significance of the component. or There are numerous important basic electrical components commonly found in the circuits of almost all peripherals. These devices are the essential building BLOCKS of electronic and electrical circuits. These ELECTRIC components can be found in great numbers on motherboards, video cards, hard disk, logic boards and everywhere else in personal computers. The electrical circuit components can be combined with each other and with dozens of other devices. Electrical circuits on different parts of equipment share similarities. Many circuits have resistors, inductors, capacitors, transformers, fuses and switches. Understanding the concepts of these components will help you while troubleshooting a circuit. THEREFORE, this article gives information about different types of electrical components and electrical component symbols which are used in electrical and electronic projects. |
