Question

Why does a bomb calorimeter have an inner chamber and an outer chamber?

Kevin Zaborsky · Accepted Answer

we need to define what the main characteristic is of a bomb calorie meter. In this question, we draw out a rough sketch of a bomb calorie meter. We know that we have a thermometer submerged in this water. In this container, you measure the change in temperature for a metal contained in a combustion chamber That gives off heat that is absorbed by the surrounding water. In the main characteristic this calendar emitter has compared to other types is constant volume That is the main characteristic of a bomb calorie meter. And we can determine the heat of combustion of a given reaction using a bomb bomb calorie meter were given value for the heat capacity of the calorie meter. We multiply that by the change in temperature. We do not need to know the mass of the material that is releasing heat to the to the surrounding water because we&#x27;re given the three heat capacity and not the specific heat capacity of the calorie meter, which means it has units of energy, her temperature and when we multiply that by the change in temperature, you get units of energy which we can use to find the entropy of combustion of a given reaction. So the main advantage of a constant volume on calorie meter is that we only need to measure the change in temperature in order to ultimately solved for the entropy of combustion of a given reaction, since we are usually told the value of the heat capacity of the calorie meter that makes this type of calorie meter convenient for experimentation.

if we replace the water in a bomb calorie meter with some other liquid, or even simply replace the water with a liquid that maybe with water that may be slightly contaminated, we would need to re determine the heat capacity of the calorie motor. That&#x27;s because the capacity of the calorie motor is a function of all of the parts of the calorie meter, including the amount and the identity of the liquid that comprises the calorie under. Sometimes people try to separate the heat capacity of the calorie emitter with including everything but the liquid, and then they some on the, uh he capacity or the heat associated with the absorption of the liquid separate. But it ends up being simpler in many cases to calculate the heat capacity for the entire surroundings, the entire everything absorbing the heat, and the calorie emitter itself is assumed to be the only parts of the surroundings that is absorbing heat. Therefore, if we were to change anything associated with the calorie murder, especially if we were to a change, change the identity of the liquid which ends up absorbing the most significant amount of the heat rather than the other parts of the calorie motor. A new calorie emitter constant would need to be determined

David Collins · Answer

The book describes calorie symmetry as the measure of heat that evolves or is absorbed by a chemical reaction. That calorie symmetry is much more than that. We can define calorie symmetry in general terms as simply the process of measuring heat flow. It could be flow that occurs during a chemical reaction, but it also could be a measure of heat flow as heat flows from a hot object to a cold object. Kalorama tree is simply the process of measuring heat flow and an example is the heat that flows during a chemical reaction. A coffee cup calorie mature is open to the atmosphere, so it measures heat flow at constant pressure. A bomb calorie emitter has a specific volume that stays constant, so it measures heat flow at constant volume, measuring heat flow at constant volume corresponds to the change in internal energy measuring heat flow at constant pressure corresponds to delta H. Or the change in and now being.

David Collins · Answer

a bomb calorie meter is a calorie meter that measures the heat transferred at constant volume, while in 80 Batic calorie meter is used for specific cases of monitoring runaway reactions, whereas the temperature increases the rate increases.

Hello Today we&#x27;ll be talking about Chapter 15 Questions 68 which asks us to consider a calorie meter like you might find in a college or high school teaching chemistry lab. And so we have a cup here with some water in it, and we&#x27;ll note that this is a foam cup Styrofoam cup, and then we have her thermometer, which reads out the temperature. And then perhaps we have some ice that we&#x27;re going to put in to the cup, which we know is it zero degrees Celsius ice, and we&#x27;re going to measure the temper, chain temperature change and learn something about heat transfer. Now, the reason that we want a foam cup is because the only measurement that we&#x27;re making is that of the liquid water in the cup. So any energy that goes into the ice from the water will be in noted by this temperature dropping. But if the water is able to get ah heat from an outside source, then we don&#x27;t actually know how much energy is coming from the liquid water versus coming from, say, some heat outside of the cup. And so we want to have the foam cup as a new insulate. Er, we want to make sure that the Onley energy being transferred is between the liquid water and the ice water. Nothing else. Not from the air around it. Not from Thea surface underneath the cup, nothing else. The only energy transfer are between the two forms of water, and the insulated foam cup allows us to achieve this.

Problem 2 Easy Difficulty

Why does a bomb calorimeter have an inner chamber and an outer chamber?

Answer

Two make calorimeter insulated so that chamber could not exchange heat. There will be no heat loss to surrounding and all the released from the reaction can be used to vaporize water. That is why water circulation in in outer and inner chamber makes insulated.
