# Charles's law

Learn about Jacques Charles's experiments with gas and temperature, and discover how heating a gas in a closed container under constant pressure increases its volume. Uncover Charles's Law, the concept that volume divided by temperature is constant, and see it applied to real-world problems. Created by Ryan Scott Patton.

• at 0 K is given with a symbol is it that we should write in that symbol?
• That symbol is Phi...it is often used for denoting zero...so it really is just 0K or Absolute Zero:)
• Can you do a video on how to do a problem? rather than just talk about how to do it and where the equation came from
• How is it possible for gases to have no volume?
• Becuase they are so tny. They are really small. Theoretically gases don't have their volume. They take up the volume of the container they are in. So at absolute zero (maybe that is whay you meant), the movement of the gas particles virtually caeses.
It is actually when some materials become SUPERCONDUCTORS. These materials can levitate magnets. This materials might also be our future transportation. SO imagine all the cars would actually move from one place to another without even rubbing against the road. They will basically levitate. SO there would be no friction and it will increase the efficiency of our civilized transport system massively!
• I thought according to Avogadro's law, all gases at the temp/pressure with the same number of moles will have the same volume?
• Yes. Jenna that is very true according to Avogadro's Law
• For the question at the end, can I just simply take the temperature in Celsius since it'd be cancel out anyways?
• If a fixed quantity of gas at a constant pressure occupies a volume of 8.5 liters at 29 degrees Celsius what will the gas occupy if the temperature is raised To125 degrees

• Roughly 11 .2 L
• shouldn't 1 mole of any gas take up 22.4 litres then in the graph it didn't represent this. can any please explain this.

• Yes it is true...but in the graphs fr Charles law... We r taking no. Of moles as constant...plus 1 mole =22.4 Lit ONLY at 0 degrees Celsius or 273.15K....if u see in the graph...Temperature is Varying...and to prove the above fact...u can see on internet the actual readings of the graph for 1 ATM pressure that at 0c...all gasses will have same volume of 22.4 L...in this graph they have taken different gasses at different pressures and hence u get confused.. So don't worry:)
• What's the exact constant that this equals to in the end? Also, for Boyle's Law, what is the constant as well? If you mentioned it, it would be `better`.
