Explain, at the molecular level, why evaporation leads to a cooling effect 00:49​ b. Explain why liquids with stronger intermolecular forces tend to have lower rates of evaporation at a given temperature compared to liquids with weaker intermolecular forces 01:56​ c. One feels a sense of cooling under the fan after a bath. Explain 02:30​ d. How a dynamic equilibrium is established during evaporation of a liquid in a closed vessel at constant temperature 03:28​ e. The boiling point of water is different at Lahore and Murree Hills. Explain 04:11​ f. Discuss two significant consequences of the lower density of ice compared to liquid water in natural environments 04:51​ g. Why boiling point of a liquid increases when the external pressure rises? 05:23​ h. Mention four items in which liquid crystals are used 05:45​ i. How do you differentiate between crystalline solids and amorphous solids? 07:08​ j) Propanone (CH₃COCH₃), propanol (CH₃CH₂CH₂OH) and butane (CH₃CH₂CH₂CH₃) have very similar relative molecular masses. List them in the expected order of increasing boiling points. Explain your answer 08:26​ k.Discuss how hydrogen bonding is responsible for the relatively high surface tension of water 09:08​ l) What type of intermolecular forces will dominate in the following liquids? 10:09​ m) The boiling points and molar masses of hydrides of some first row elements are tabulated below. Suggest reasons for the difference in their boiling points in terms of the type of molecules involved and the nature of the forces present between them. 📚 Watch Complete Playlist: 👉 [    • 11 Class Chemistry (Ne...  ​] 📚 Watch Solved Exercise Full Playlist 👉 [    • 11th Chemistry Solved ...  ​] 🔔 Subscribe for More Lectures: 🎓 Subscribe for Complete 1st Year Chemistry Coverage: 👉 🎯 Covered Short Questions from Chapter 5: States and Phases of Matter (11 chemistry | 11th chemistry): 👉 London dispersion forces 👉Vapour pressure and boiling 👉Anomalous expansion of water 👉 ΔHv values of different liquids 👉 Surface tension causes 👉 Intermolecular forces types 👉 Crystalline solids vs amorphous 👉 Viscosity trends 👉Liquid crystals explanation solved exercise 11 chemistry , 11 chemistry solved exercise , 11th chemistry solved exercise , 11 chemistry states of matter solved short questions, 11th chemistry states and phases of matter, 11 chemistry chapter 5 solved short questions, 11th chemistry intermolecular forces, 11 chemistry London dispersion forces mcqs, 11 chemistry boiling and vapor pressure, 11th chemistry hydrogen bonding, 11 chemistry surface tension explanation, 11th chemistry exercise short question , states and phases of matter 11th chemistry exercise, 11 chemistry crystalline solids exercise short questions, 11 chemistry new book 2025 mcqs, fsc part 1 chapter 5 chemistry solved, chemistry lecture #11thChemistry​ #11Chemistry​ #StatesOfMatter​ #PhasesOfMatter​ #SolvedExercise​ #ChemistryNewBook2025​ #FScPart1​ #AsimMushtaqAnsari​ #MCQswithExplanation​
