A gas enclosed in a piston that has a volume of #245*mL# at #0# #""^@C#, will express what volume at #95# #""^@C#?
At constant pressure,
The above was simply a restatement of Charles' Law.
Given your problem, and converting the temperatures to absolute values:
Note that for these problems I am obliged to turn temperatures into absolute temperatures (why? because the Gas Laws assume absolute temperatures). I am NOT obliged to use standard volumes if I am consistent - I could have used pints and gills if I knew what they meant! Thus a measurement in millilitres is quite acceptable.
