      You dont have to put down something just to appreciate some other thing! Professor Dave is awesome and so is Hank Green. They both have different styles of teaching. Prof. Dave teaches in a calm & composite manner. Hank teaches in a more fun & hands-on kinda manner. And I think both are amazing in their own unique ways.

    As a planetary astronomer dealing with atmospheres, I'm much more comfortable using SI units, a weird unit we thought up for atmosphere chemistry called the kilomole (1 kmol = 1,000 mol), and an appropriately adjusted SI value of R (8,314.4598 J K^-1 kmol^-1). But I suppose if I had to deal with amounts of gas that could fit in vessels and tubes in a chem lab, I'd use the units you use here!😁

    Can you please check am I right ( my answers are 1,3,4): For an ideal gas which of the following statements are correct:
    1. Increasing the temperature of a gas at a constant pressure increases its volume
    2. Increasing the pressure of a gas at a constant temperature increases its volume
    3.Increasing the temperature of a gas at constant volume increases its pressure
    4.At the same temperature and pressure one mole of helium gas occupies the same volume of one mole of argon gas
    5.The ideal gas law applies only to monoatomic gases.

  • @PentameronSV

    3:23 I still don't understand how the gas constant works.
    EDIT 1: I mistakenly thought that 'R' equals '0.0821 multiplied by whatever fraction shown on the right'.
    Am I correct in saying that the fraction at the end of the equation symbolises the many units for the number '0.0821'?
    Like, for example, the user can freely choose to use the unit 'L', making 'R = 0.0821L'?
    EDIT 2: Okay, I get it now. At 4:29, in the longest equation under the second question, the aforementioned units are necessary for the other units to cancel out in both the numerator and denominator of the fraction.
    To quote Professor Dave himself at 3:26, the gas constant (R) "makes these calculations intelligible in our man-made units."

Instead, near whole numbers are given in the questions. therefore, we don’t need nor use calculators while solving questions. Given these circumstances, I realized I don’t really know how to do these calculations 🫠 I was wondering if the calculations in checking comprehension part require a calculator, or am I expected to be able to do the calculations without it? It’d be greatly appreciated if you could answer me 🫶🏻

  • @gabriels2395
    @gabriels2395 6 лет назад +3

    Hi Professor! Thank you so much for your videos!!. I have a question. Is it possible to *increase the pressure* and at the same time *not to increase the temperature* as a result of this? I think about the diesel motors (for example) that use high pressure for diesel to ignite within the piston and cause the explosion, which I think is because the increase in pressure *heats* the diesel enough as for this to explode (the increase in pressure increases, *consequently,* the temperature).

    • @ProfessorDaveExplains
      @ProfessorDaveExplains  6 лет назад +5

      sure one can definitely keep temperature constant! compression will not always be accompanied by temperature increase. this is called an isothermal process.

    • @gabriels2395
      @gabriels2395 6 лет назад

      thank you for replying professor! This is a bit counterintuitive to me though. I found something on Wikipedia _en.wikipedia.org/wiki/Isothermal_process_
      _...Doing work on the gas increases the internal energy and will tend_
      _to increase the temperature..._
      it says (to me) that the increase in pressure increases the internal energy, which needs to leave the system for the temperature not to change (going to the environment as heat). So there is an increase in temperature just that the system makes up for this by releasing such heat. Is there any instance in which increase in pressure would not make us deal with heat production (for us not even to need to get rid of any produced heat?)

    • @ProfessorDaveExplains
      @ProfessorDaveExplains  6 лет назад +2

      yes that would be an adiabatic process! and in fact, boyle's law talks about pressure and volume changing with temperature remaining constant. so it's just about tweaking the parameters.

    Can someone answer this please: I work in blown film extrusion and cannot answer this question. If you have a bubble which is 50microns thick with a constant volume of 10 litres on air inside, why is it when you increase your thickness to say 100 microns the with the same volume of air in the bubble, the bubble increases in size? What is the science behind this?. Its also worth noting in blown film, we have a frost-line which is the point where the polymer has solidified and no longer able to stretch/mold. So when we take the output up, the frostline increases under the same air conditions it's taking longer for the air to cool then polymer as its become thicker.
