hello dearExplanation:The Kelvin scale is used in gas LAW problems because the pressure and VOLUME of a gas DEPEND on the KINETIC energy or motion of the particles. The Kelvin scale is proportional to the KE of the particles… that is, 0 K (absolute zero) means 0 kinetic energy. 0 °C is simply the freezing point of water.Hope I helped you if I did please mark me as brainliest

The ideal gas law, also CALLED the general gas equation, is the equation of state of a hypothetical ideal gas. It is a GOOD approximation of the behavior of many gases under many CONDITIONS, although it has several limitations.

tion:Since oxygen has 8 electrons it can USE up, and the 2 HYDROGENS only use 4, that means there are 2 pairs of lone electrons (or 4 electrons left). And since electrons repel, the SHAPE of WATER will not be linear, but a tetrahedral BENT shape.

री हरमंदर साहिब, पटना में गुरू गोविंद सिंह जी की लिखाई में मूल-मंत्र वाला पत्रExplanation आदिग्रन्थ सिख समुदाय का प्रमुख धर्मग्रन्थ है। इन्हें 'गुरु ग्रंथ साहिब' भी कहते हैं। इनका संपादन सिख समुदाय के पांचवें गुरु श्री गुरु अर्जुन देव जी ने किया। गुरु ग्रन्थ साहिब जी का पहला प्रकाश 30 अगस्त 1604 को हरिमंदिर साहिब अमृतसर में हुआ। 1705 में दमदमा साहिब में दशमेश पिता गुरु गोविंद सिंह जी ने गुरु तेगबहादुर जी के 116 शब्द जोड़कर इसको पूर्ण किया, इनमे कुल 1430 पृष्ठ है।गुरू ग्रंथ साहित्यलेखक:सिख गुरु, सन्त कविदेश:पंजाब, भारतभाषा:गुरमुखी लिपीप्रकार:बाणीप्रकाशन तिथि:1604पृष्ठ:1430एक ग्रन्थगुरुग्रन्थ साहिब जी में मात्र सिख गुरुओं के ही उपदेश नहीं है, वरन् 30 अन्य सन्तो और अलंग धर्म के मुस्लिम भक्तों की वाणी भी सम्मिलित है। इसमे जहां जयदेवजी और परमानंदजी जैसे ब्राह्मण भक्तों की वाणी है, वहीं जाति-पांति के आत्महंता भेदभाव से ग्रस्त तत्कालीन हिंदु समाज में हेय समझे जाने वाली जातियों के प्रतिनिधि दिव्य आत्माओं जैसे कबीर, रविदास, नामदेव, सैण जी, सघना जी, छीवाजी, धन्ना की वाणी भी सम्मिलित है। पांचों वक्त नमाज पढ़ने में विश्वास रखने वाले शेख फरीद के श्लोक भी गुरु ग्रंथ साहिब में दर्ज हैं। अपनी भाषायी अभिव्यक्ति, दार्शनिकता, संदेश की दृष्टि से गुरु ग्रन्थ साहिब अद्वितीय हैं। इनकी भाषा की सरलता, सुबोधता, सटीकता जहां जनमानस को आकर्षित करती है। वहीं संगीत के सुरों व 31 रागों के प्रयोग ने आत्मविषयक गूढ़ आध्यात्मिक उपदेशों को भी मधुर व सारग्राही बना दिया है।गुरु ग्रन्थ साहिब में उल्लेखित दार्शनिकता कर्मवाद को मान्यता देती है। गुरुवाणी के अनुसार व्यक्ति अपने कर्मो के अनुसार ही महत्व पाता है। समाज की मुख्य धारा से कटकर संन्यास में ईश्वर प्राप्ति का साधन ढूंढ रहे साधकों को गुरुग्रन्थ साहिब सबक देता है। हालांकि गुरु ग्रन्थ साहिब में आत्मनिरीक्षण, ध्यान का महत्व स्वीकारा गया है, मगर साधना के नाम पर परित्याग, अकर्मण्यता, निश्चेष्टता का गुरुवाणी विरोध करती है। गुरुवाणी के अनुसार ईश्वर को प्राप्त करने के लिए सामाजिक उत्तरदायित्व से विमुख होकर जंगलों में भटकने की आवश्यकता नहीं है। ईश्वर हमारे हृदय में ही है, उसे अपने आन्तरिक हृदय में ही खोजने व अनुभव करने की आवश्यकता है। गुरुवाणी परमात्मा से उपजी आत्मिक शक्ति को लोककल्याण के लिए प्रयोग करने की प्रेरणा देती है। मधुर व्यवहार और विनम्र शब्दों के प्रयोग द्वारा हर हृदय को जीतने की सीख दी गई है।Plzzzzzzzzzzzzzzzzzzz VOTE for my ANSWERAND MARK my answer as BRAINLIEST and follow me

A suspension is a type of solute in a SOLVENT which totally floats or sinks in it WITHOUT being DISSOLVED in it. On the other hand, A colloid is also a solute in a solvent but it dissolves to greater extent than a suspension. Colloid particles cannot be seen from outside but they can be seen in Tyndall effect (scattering of particles in light). For example: MUD in water is a suspension and Aerosols are COLLOIDAL particles.Hope this helps.

First law of thermodynamics:-The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an ISOLATED system. The second law of thermodynamics states that the entropy of any isolated system always increases.Second law of thermodynamics:-Energy is the ability to bring about change or to do work. ... The Second Law of Thermodynamics states that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the STATE will always be less than that of the initial state." This is also commonly referred to as entropyI HOPE this answer MAY help you sister

Postulates of Werner's TheoryThe CENTRAL metal atom in the coordination compound EXHIBITS TWO TYPES of valency, namely, primary and secondary linkages or valencies. Primary linkages are ionizable and are satisfied by the negative IONS. Secondary linkages are non-ionizable. These are satisfied by negative ions.
