how did the exams go?

😂,oh sorry

+TheRandomNess Appreciate the sentiment mate, but would appreciate if you don't use Jesus's name like that!

Lol, my bad, got too used to blasphemy.

He’s calling Jesus a legend

Science Shorts great stuff even corrects blaspheme definitely A legend mate!

+Timo You're welcome!

same man, gl

Couldn't agree more 😂 I've never felt soo heartbroken after an exam. The thing is my school doesn't teach mechanics in mathematics instead we do decision and statistics. Thus I was even worse off :( It felt like all my effort in revision and past papers were useless

pranish gurung , my teacher and school is going to complain about that exam ... tell your teacher to complain too

+Nima the leagend Nimatheleagend Sorry to hear that mate. Unfortunately physics exams not only require you to understand concepts, but apply your understanding to unseen situations. The only way you get better at that is by practising questions. I do plan to go through past papers once there are more available. As a teacher, I have access to AQA's exampro which has hundreds of questions that I give to my students. You could always ask your teacher to do the same.

Science Shorts . So what's your opinion on the AQA physics paper 1 ? Were your students happy with the exam ?

is this AQA or Edexcel?

You got the money yet?

@@oneinabillion654 Soon (TM)

@@smokescreen9119 Okay. Great

Hey, how was your result?

@@zayeedhumayun2502 I also heard many people got straight A and only Physics B, so they dropped the subject. This will make A2 grade for Physics even higher as the same strong candidates remains and are gonna take the test with me. Imagine 10 strong candidates vs 10 strong and 5 less strong. The grade will be so much higher man...

@@oneinabillion654 Hey, just read the comment and I think you've done amazing. Wonder where you are now? Are you studying at a university or did you go down a different route? i'm planning to do engineering at Uni but I'd love to hear from someone who is in a similar situation that I think I am currently in. Look forward to hearing from you :)

@@teatime9198 Wow this was me 2 yrs ago? 😂 Went to uni, the usual route. Got into electronics engineering (Math+Physics degree was too exp). 2yrs passed and started to love smth else instead, coding. (So yea, there's some procrastination with sch now) PS: I've lost interest in electronics As for coding, I found a "business partner" in the same uni and we're on to making a social media app. In the short term, making some money tutoring IGCSE and A levels (what else to do?). Yea, probably will use this to fund my startup (social media app) if all goes to plan. So yea, life progresses and not much has, or I think could've been done in the past 2yrs seeing the situation outside. Stay safe! All I want to say to u is go for what u like, if u can. Some ppl (like me) don't even get to choose due to financial constraints and disadvantageous location. And always stay happy and positive. Life is full of surprises. Your goals might shift in a split second. Your dreams might take a different form as u learn more about the world. Keep an open mind and be creative! And lastly, spend some time with you friends :) I think u know what I mean :D

tallteacher Thank you for the great explanation, it really cleared things up. I just hope when it comes to the exam I'm not penalised for saying it as a minimum amount of kinetic energy.

Depends on the other units for context. 8.314 kPa-L/mole-K 8.314 kPa-m^3/kmol-K 8.314 Pa-m^3/mol-K 8.314 kJ/kmol-K 8.314 J/mol-k

When the volume increases, the gas is doing work. When the volume decreases, work is being done on the gas Work is the area under the PV curve, when V is on the horizontal axis. Since neither P nor V can be negative, this means that the direction of work only depends on which point is your starting point, and which point is your ending point, when finding this area.

expansion = work done by the gas compression = work done on the gas

You aren't equating all in one equation. There is an R-constant to make all the units consistent. A given sample of gas has a particular temperature, pressure, volume, and number of molecules. The ideal gas law simply combines the proportionalities stated in all four base case laws, and promotes it from a proportionality to an equation by inserting the R-constant or Boltzmann's constant.

No because both are dependent varriables so it doesnot matter

Lol

《 IAmBasic 》 u keep it constant

You make these values constant or assume they are constant

By definition. That's what Boyle, Charles, Amonton, and Avogadro did, in order to do their original experiments to discover these laws.

👍

Yep - weirdly though, not a word we see crop up in exams!

@@ScienceShorts it's really interesting to see how curriculums change across countries. I am taking a test from this tomorrow, and it's the reason I watched this video! Isochronic is a term that I and my schoolmates will probably have to know how to explain.

K is a constant, its added as proportionality factor

My teacher said it’s R guess it’s the same

@@SgtIndustrial R is what we call it when working in molar form. k is what we call it, when counting individual molecules or atoms. It is all ultimately the same constant. The k is called Boltzmann's constant, and the R is Boltzmann's constant times Avogadro's number to put moles in the denominator. Constant starts with a k in German, and makes the same sound as c most commonly makes, so it is common to see k standing for constant in general. The reason we call it R, is speculated to be from the name of the French chemist named Regnault.

one ring to rule them all

I nearly put in, but it's a term I've never seen in an exam.

@@ScienceShorts I guess you haven't seen a Nigerian exam then 😂 It's comes out, like.....

If that were true, you'd be given temperatures to 0.01 degrees Celsius.
