Got my A levels result today. Got an A in physics, B in maths and a D in Computer science. I owe you that A in physics. Thank you for your content!

Thank you @Science Shorts for doing a kind gesture for all A-Level students. I had no hope for Physics but after discovering your channel, I watched every video which will come out of the exam. You gave me hope in doing Physics A-Level. I have just done the Physics A-Level P4 at Thursday and awaiting for the results. Thank you for your dedication and Keep up the Good Work. 😁😁

Do you think you could go over the differences between the four stroke petrol engine and a diesel engine? My teacher went over it and I have a basic understanding but I reckon you'll be able to explain it a bit clearer. Thanks

@Mak007-h5s 3 года назад

Can we watch your videos of explanation and past papers for CAIE alevel?

@anniemoses9478 3 года назад

Why does isothermal compression happen at constant temperatures and why does the volume decrease and pressure increase? Also at a colder temperature I understand that the gas expands less but is that why the volume is lower?

@rgravi Год назад

hi what if the gas is changing state? will deltaU = 0? as it depends on PE as well?

@lamb8657 Год назад

hi, i have my a level phyics paper 2 on friday but i was just wondering do we know to know all of this for AQA specification? because when i was covering thermal physics earlier this year, i've not come across any of this except from the basics of the first law of thermodynamics

@ScienceShorts Год назад

Only for Engineering optional module

@xQryptic 4 года назад

@Science Shorts Hi, I have a question. If pV/T = constant, how come decreasing the temperature increases the p and v? Due to the equation, shouldn't it be the other way around? Thanks.

@ScienceShorts 4 года назад

Er, increasing temperature increases pressure!

@xQryptic 4 года назад

Science Shorts yeah I’m not going to lie I was having a mental spasm when asking that question 😆. Thanks for the clarity and quick reply, however :)

@jakequaza3567 3 года назад

you said w=pdeltaV only applies for constant pressure but at 6:48 you use the same equation when p is changing? Why have you used this here?

@varundinesh555 3 года назад

I'm really sorry... at 9:44, I don't understand why he has shaded the whole thing in for when work is done by the gas, but only the bottom section for when work is done on the gas. Can someone explain please?

@ScienceShorts 3 года назад

Inside loop is net work done by gas. As in: total work done by it minus work done on it.

@Raven-pt9bf 5 лет назад

canWe write the first law like this too? Plzz reply Increase in internal energy= energy supplied by heating + energy supplied by doing work

@wafflebuckets 4 года назад

Sorry for late reply. So basically U=q+w. Here w means work done ON the system. So the first law of thermodynamics would be: The internal energy of a system equals to the sum of the heat supplied and the work done on the system

@rbanerjee605 3 года назад

If you’re rearranging the provided formula, it would be U=Q-W

@meganbannister7783 4 года назад

Do we need to know these for AQA physics alevel?

@nl1575 3 года назад

That's what I was thinking as well, I haven't learnt this yk. I don't think we have to learn the graphs, but we do have to know the first law of thermodynamics and the work done by expanding gas.

@jacobsuresh3743 3 года назад

i dont think you need to do this unless your school is doing engineering physics for the option module. not entirely sure

@jakepaterson6857 3 года назад

Hi Sir, is Q=U-W required knowledge for standard A Level? (Non-engineering physics)

@shneurjayson3020 2 года назад

@hardikb15 Год назад

it's the same thing except when gas is compressed (work is being done on the gas) which is negative

@matthewmaksimov 4 года назад

muhammad Ahmed, it is, but don’t forget that in your equation W is work ON gas, but in video W is work BY gas. There is an equation W’=-W, here W’ is work by gas, W is work on gas.
