Question

If 1.50 grams of propane is burned in a bomb calorimeter, what will be the final temperature?

A) Depends on the calorimeter design
B) Not enough information
C) Constant at 25°C
D) Temperature will decrease

Answer 1

Without the calorimeter's heat capacity and initial temperature values, the final temperature of the propane after combustion in a bomb calorimeter cannot be determined, so the answer is B. 'Not enough information'.

Step-by-step explanation:

To determine whether the final temperature can be calculated when 1.50 grams of propane is burned in a bomb calorimeter, we need additional information such as the heat capacity of the calorimeter and the initial temperature. Calculating the change in temperature requires knowing the heat released by the combustion of propane and the calorimeter's heat capacity. However, with the information provided, we cannot determine the final temperature. Hence, the answer is B) Not enough information.

If the heat of combustion of propane is known, and if the calorimeter's heat capacity is given, then the amount of heat produced (q) during combustion can be used, along with the calorimeter's heat capacity, to calculate the temperature change. This is illustrated in the examples where specific masses of substances are burned, and the resulting temperature change is calculated using the calorimeter's heat capacity.
