Question

a gas takes up a volume of 17 liters, has a pressure of 2.3 atm, and a temperature of 299 K. what is the final temperature of the gas if the final volume is 14 liters and the pressure is constant

Answer 1

when pressure is constant we can use the charles law:

`(V_1)/(T_1)=(V_2)/(T_2)`

in this case we need to solve for T2 and use the data provided in the text:

`T_2=(V_2T_1)/(V_1)=(14L\cdot299K)/(17L)=246K`

So the final Temperature is 246K
