Sir I have a confusion regarding the language of a question. Though it's not related to this video, I hope you can help me to figure out the solution. It was actually a question in NEET chemistry 2024. I have no problem with the concept of the question but confusion from a linguistic point of view. The question is The Henry's law constant (Kh ) values of three gases (A,B,C) in water are 145, 2×10^-5 and 35 kbar , respectively. The solubility of these gases in water follow the order 1. A>B>C 2. B >A >C 3. B >C >A 4. A>C> B There is an inverse relation between Henry's law constant and solubility, so i marked the answer as 2. But the answer according to the answer key is 3. I took k bar to be the unit of the last term only and considered the other two in bar. K bar can also be thought of as 10^3 bar . Moreover the comma was before the word respectively so I ascribed the unit to the last term only. Have I misunderstood the question or is the language actually confusing? Please help me if possible.
Yes, it is a badly worded question. Three values all in kbar. so A is 145kbar, B is 2x10^-5kbar, and C is 35kbar. So A is 145000bar, B is 0.145bar and C is 35000bar. So A, C, B in order of largest first but because of inverse relationship the answer order is B,C,A so answer is 3. Hope that helps! Keep studying hard!
@@AnthonyFrancisJones Should there have been a comma before kbar? I considered k bar for the last term only and took the others in bar so got option 2. And thanks a lot for replying I took 145 bar, 2×10^- 5 bar and 35 k bar So the order came to be B>A>C 😞😓
Yes, every value (unless it is a real trick question!) should have units with it, so go with kbar for all of the numbers in this case. Badly set question I would say! You have got it now though! It shows me that you understand the science really well but need to keep practising this type of question so you are used to the things they get up to! Not your fault!
@@AnthonyFrancisJones Thanks for the encouraging words. I actually took it to be a tricky question because if indeed kilobar was meant for the last value, most people would miss it. I took it that way because tricky questions are often asked in entrance exams. I was worried about my English grammar 😅
Wow! This is so cool.
Yes, I love these old steam toys and they are great for demonstrating engineering principles too!
