The question is, could an endo thermic reaction We used to measure the heat capacity of the calorie motor? And the answer is yes. A calorie meter will absorb or lose energy according to its heat capacity. Still, in most cases, an excellent thermic reaction is used, and we measure the heat capacity of a calorie meter by the temperature change Uh, which is an increase in temperature because of the excellent Emmick process. However, heat capacity can be measured by monitoring the heat gained or lost, or the heat resulting in an increase in temperature or a decrease in temperature of the Kalorama Turner. Heat capacity in general describes the change in temperature as a function of the absorption of heat or the loss of heat. It doesn&#x27;t matter.

this question wants to know if we can use Hess&#x27;s law for Delta E. The change in internal energy the same way that we use it for Delta H, Delta S and Delta G to review Hessels lock can be used to calculate any state function. Any change in the state function because the state function is independent of the path and only depends upon the initial state in the final state some state functions that you are aware of our and Cal P entropy and gives free energy. Because Delta E is also a state function, change in internal energy just depends on the initial state and the final state, not the path that resulted in that change in energy, which is W work plus heat. Then Hess&#x27;s law is appropriate to be used to calculate Delta E if we know the energy associated with the initial state and the energy associated with the final state. When the change in internal energy can be calculated by simply taking that difference, or if we know the Delta ease for multiple reactions and weaken some them up to get a final reaction. Then, in a Hess&#x27;s law fashion, we could sum up the Delta ease to get the Delta E for the overall reaction

Hello Today we&#x27;ll be talking about Chapter 15 Question 16 which asks us to consider how we might go about calculating how much heat was transferred in or out of an object or substance when its temperature changes. And so we have one equation that relates heat and temperature change. That&#x27;s Q equals. M See P. Delta T. And so first, let&#x27;s just define our variables. Q. Is the heat absorbed or lost by the ah material? So Q is positive if the heat is absorbed and negative if the heat is lost, mm is the mass so mass of object that we&#x27;re looking at. So, for example, if we have a rock that weighs two kilograms, then this rock the two kilograms is the mass of the rock that will be looking at and how much he dis absorbed are released by the rock. Now the CP is thes specific heat, and that is the amount of energy required to raise one gram. So it&#x27;s the amount of jewels required to raise one gram of some substance. It&#x27;s specific to each individual substance one degree Celsius. So this is the units of jewels over grams degrees Celsius and for example for water water has Thea he kept in the specific heat of 4.18 four jewels, which will raise one gram of water one degree Celsius. And lastly, Delta T is just the change in temperature of the object, sir, Change in temp and so likely if we want to calculate the heat, then we need to know the mass, and we need to know the change in temperature. And also we need to know the specific heat, though this is constant, which, uh, so long as we have a known pure material. So hopefully this helps you understand a little bit more about we calculate about how we calculate heat that is transferred in and out of an object when the temperature changes. Thank you.

My name is Aziz. We know that we can calculate that the H or suck track the bone. The energy broke in negative to the some off boned energy for me. So here we broke See the bill bone See and broke. Seal Siem and broke for ch Negative. We form it CC loss toe CCL glass for C edge Here we can neglected this four ch with this force yet so it will be equals Energy off syllable Bon c 6 to 0 c l C l 242.7 and cc form It is 347 And here CCL Street three line. So the total dealt h. It will be negative. Wall 62.3 kilo. June. Thank you.

Ahmed Ali · Answer

Hello, everyone. My name is on this question. As we don&#x27;t Delta H is calculated at the foreman. The some off the bone, the energy procaine negative to some Oh, warmed energy for men. So it is equal toe, toe all seep on the plus six image negative toe for image toe NBC Los CEO plus two Well, which there are beating here. So we will neglect. Is this with this and neglect? Is this for? We sport off this so remaining it is too. So when we calculating, then you have only one See also seven for five and two niche. So it will be to time 393 and tow ends. It will be to time to seven sex and to just will be toe time for 60 So the daughter is It will be five mine kilo joule. Thank you

Problem 3 Easy Difficulty

Can you measure the heat energy of a combustion reaction by placing a thermometer directly into the l ames? Explain.

Answer

No, placing a thermometer in the fl ames measures the temperature of the combustion reaction, but it cannot measure the total heat energy given off by the reaction.
