The energy content of a certain food is to be determined in a bomb calorimeter that contains 3.5 kg of water by burning a 2-g sample of it in the presence of 100 g of air in the reaction chamber. if the water temperature rises by 3.2°c when equilibrium is established, determine the energy content of the food, in kj/kg, by neglecting the thermal energy stored in the reaction chamber and the energy supplied by the mixer. by calculating the rough estimate of the error involved in neglecting the thermal energy stored in the reaction chamber, do you think it is reasonable to disregard the change in the sensible energy content of the reaction chamber in the analysis

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
