Your task is to measure the amount of energy evolved during the combustion of some hydrocarbon, then the ideal technique for this experiment would be : Bomb calorimetry
<h3>What is bomb calorimetry?</h3>
Hydrocarbons are combustibles means that they can react in a combustion reaction to produce energy. To measure this energy, it's a necessary equipment so that the reaction can be placed in a controlled way.
The bomb calorimeter is the equipment, which is an adiabatic vessel, with water and heat is calculated based on the increase in the temperature of the water.
Coffee-cup calorimetry is used to measure the heat of a dissolution reaction and bomb manometry is used to measure the pressure.

Answer:
V₂ =31.8 mL
Explanation:
Given data:
Initial volume of gas = 45 mL
Initial temperature = 135°C (135+273 =408 K)
Final temperature = 15°C (15+273 =288 K)
Final volume of gas = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 45 mL × 288 K / 408 k
V₂ = 12960 mL.K / 408 K
V₂ =31.8 mL
