How hot must the air in a balloon be heated if initially it has a volume of 750 L at 20 degrees celsius and the final volume must be 1000 L?
Jcannon4
remains constant throughout the operation.
The only trick to this whole thing is to understand that
-- At constant pressure, volume is directly proportional to temperature.
Volume2/Volume1 = Temperature2/Temperature1
-- 'Temperature' means absolute temperature ... Kelvin, or (Celsius + 273).?
The initial temperature of 20 C is absolute temp of 293 K.
If the pressure remains constant, then
Absolute-temp2 = Absolute-temp1 x (Volume2/Volume1) = 1,000 x 293/750 = 3902/3 K.
°Celsius = Absolute - 273 = 117 2/3 ° C.

A piece of iron absorbs an amount of heat when it is heated from 22 degrees Celsius to 28 degrees Celsius- How many joules does it absorb?
There is not enough information in this problem to answer the question. You must know the mass of the iron to find the amount of joules used to heat the iron.
What is the final volume of a balloon that was initially 500.0 mL at 25 degrees Celsius and was then heated to 50 degrees Celsius?
Change Celsius to Kelvin by adding 273.15. 25 C = 298.15 K 50 C = 323.15 K An equality. 500.0 ml/298.15 K = X ml/323.15 K 298.15X = 161575 X = 541.925 milliliters -------------------------------you do significant figures
