We use the ideal gas equation in order to calculate the temperature of the system. It is expressed as follows:
PV=nRT
where P is pressure, V is volume, n is the number of moles, R is the universal gas constant and T is the temperature.
15 atm (.1 L) = 0.5 mol (0.08206 L-atm / mol-K) T
T = 36.56 K
Hope this answers the question. Have a nice day.

Answer and explanation:
A) An ideal fuel must:
- easy to transport and storage.
- have a high calorific value.
B) The <em>calorific value</em> for a fuel is the amount of heat - measured in Joules- which is produced during the complete combustion of the fuel. It is expressed in Joules per Kg of fuel (J/kg).
C) From the data:
mass of fuel = 2 kg
heat produced = 48,000 KJ
We calculate the calorific value by dividing the heat produced by the mass of fuel, as follows:
calorific value = heat produced/mass of fuel = (48,000 KJ)/(2 kg)= 24,000 kJ/kg
Since 1 KJ= 1000 J, we can express the calorific value in J/kg as follows:
24,000 kJ/kg x 1000 J/1 kJ = 2.4 x 10⁷ J/kg
