Bomb Calorimeter Experimental Uncertainty
A 0.842 g sample of glucose (C₆H₁₂O₆) is completely combusted in a bomb calorimeter with a heat capacity of 7.854 kJ/°C, increasing the temperature from 25.00°C to 28.76°C. When determining the molar enthalpy of combustion, which of the following contributes LEAST to the experimental uncertainty?
A
Energy from the chemical reaction of combustion
B
Energy lost through phase transitions
C
Energy transferred as heat to the calorimeter
D
Energy lost to the surroundings
