Answer:
The answer to your question is: Q = 1383.06 J
Explanation:
Data
mass = 0.740 g
Initial Temperature = 23.4°
Final Temperature = 26.9°
Cp = 534 J/°C
mass of water = 675 ml
Q = ?
Formula
Q = mCpΔT
Process
Q = (0.740)(534) (26.9 - 23.4)
Q = (0.740)(534) (3.5)
Q = 1383.06 J
The amount of heat produced with the combustion of trinitrotoluene (TNT) in bomb calorimeter is 1383.06 J.
A bomb calorimeter is given as the instrument that has been to measure the heat of combustion. The purpose of calorimeter is to measure the cross calorific value of the combustion of solid or liquid.
The combustion heat produced in the calorimeter can be calculated as:
Q = mCΔT
Where,
Q = Heat produced
m = mass of the sample, 0.740 g
C = Heat capacity of the sample, 534 J/°C
ΔT = Final temperature - Initial temperature
Substituting the values for calculating heat produced, Q:
Q = 0.740 g * 534 J/°C * (26.9 °C - 23.4 °C)
Q = 0.740 g * 534 J/°C * 3.5 °C
Q = 1383.06 J
Thus, the heat produced with the burning of 0.740 g TNT is 1383.06 J.
