      Why we have to convert to kelvin as he asked calculation of temperature in Celsius in the second problem?

  • @tdewitt451
    @tdewitt451  11 лет назад +69

    yes, it's called "gas pressure conversions." i made it a long time ago, so it looks really ghetto, but the information is solid.

    thank you. you're heaven sent to us. Chemistry looks so terrible to me but you made so simple to understand! i wish you're my teacher. More blessings to you my idol.

    Your videos have saved my life. This is my first year of teaching. I have a degree in English education and a Master's in literature, and the only teaching job I could find was a chemistry teaching job. I would've been lost this semester without your help. Thanks so much, and keep up the good work.

  • @tdewitt451
    @tdewitt451  13 лет назад +4

    @Farawla You ONLY have to convert if you have two different pressure units. Kpa, atm, mmhg are all fine if BOTH pressures are in those units. So if P1=23 kpa and P2=84 kpa, you're fine. But if you have P1=23 kpa and P2=4.5 atm, then you have to convert one of those two pressures so that they're both in the same units. Does that make sense?

    I went back to school to become a Veterinary Technician and I am currently taking Chemistry. Unfortunately, I have a teacher that just reads off power points and doesn't show us problems or solve problems together with us (even when we ask). I was suffering through Chemistry until I saw your videos. Thank you so much! I will probably pass this class and go on to the Vet Tech program because of you! *hug*

    Don’t be fooled by his young look. His ability to teach will amaze you and make you love learning. He is a great communicator and teacher! It is always such a pleasure to see how he is able to excite learning and pique your interest in learning more about the subject. I seek his videos on the related topics before reading my biological chemistry textbook!!

  • @axelmiller3441
    @axelmiller3441 4 года назад +2

    Another way to solve the first problem would be cross multiplying. If you were looking for P2, for instance, you would multiply P1 and T2, and multiply P2 and T1. This would get you P1xT2=P2xT1. To get P2, you have to isolate it, or get everything else on the other side of the equation. So to get P2 on on side, you would divide T1 from both sides, because if you do something to one side, you have to do it to the other. T1 divided T1 cancels it out on the right side. On the left side, you put the entire part over T1 to get P1xT2 divided by T1, or P1xT2/T1. This leaves you with P1xT2/T1. Then you just plug in the numbers and solve! I hope this helped! This took a while to write (I am in 8th grade btw, so its a little confusing to me).

    Tyler I somehow have 'hot' wheels;
    My tyres are flat and have an air temperature of 293 Kelvin and a pressure of 101.3 kPa.
    If I pump my tyres up to 230 kPa what is the temperature inside the tyres?
    T2 = T1 x P2/P1
    T2 = 293 x 230 kpa / 101.3 kPa
    T2 = 665 Kelvin!!
    This cannot be right - where did I go wrong?

    Hi can you answer this.
    An aerosol container has a pressure of 3.00 atm at 30.0°C. what is the new pressure in the aerosol container if it is thrown into a fire with a temperature of 600°C? The aerosol can explode if the pressure inside exceeds 7.00 atm. Would you expect the can to explode?
