Question
energy e. determines the direction of heat flow specific heat f. ability to do work heat capacity g. net change in heat energy is negative In a Bomb calorime ter, an endothermic reaction would be indicated by? a. Increase temperature of the water b. Decrease temperature of the water c. Unchanged temperature of the water d. Increase in water level questions 3 thru 5 answer true (T) or false (F) All combustion reactions are classified as endothermic reactions The amount of heat needed to raise the temperature of 1 gram o 1°C is the specific heat The definition of a calorie is very similar to that of heat capac f methane is 802J/mol, how many jc f methane? (4ptExplanation / Answer
1) In bomb calorimeter endothermic rection is indicated by decreased temperature of water because the bomb calorimeter is immersed in water while if the endothermic reaction occurs the heat energy is absorbed from the surrounding water and utilizes it so temperature decreases
2) All combustion reactions are classified as endothermic -false they are almost exothermic reaction release energy in the form of heat
3) The amount of heat needed to raise the temperature of 1 gm and 1C is specific heat -true
