A sample of gas is found to occupy a volume of 900cm^3 at 27 degree Celsius, calculate the temperature at which it will occupy a volume of 300cm^3, provided the pressure is kept constant.

Explanation:

Here, V1=900cm3, V2=300cm3

T1=(27+273)K=300K, T2=?

Applying Charles's law,

V1T1=V2T2

∴T2=V2T1V1=300cm3×300K900cm3=100K

=100−273=−173∘C

Hope this helps

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
