Question

Hello, So i finished my bomb calorimetry experiment last week. I am writing an introduction. I was wondering is someone can explain while Ccal (heat capacity) is independent of temperature. I want to explaint this properly however, my textbook does not give a good explanation and I looked online but, it seemed sketchy. Thank you for your help.

(sample and oxygen gas) to be the system while, the water and bomb can be related to the surroundings. This allows us to find the internal energy (AU) for the reaction. surr Ccal Ceal is the surroundings of the system. This is independent of temperature (T) since, . Thus, allowing the energy of combustion to be monitored to later calculate the Ccal which is also known as heat capacity.

Answer 1

Calorimetry has a special benefit for thermodynamics. It tells about the heat absorbed or emitted in the isothermal segment of a Carnot cycle. The net change of the body's internal energy during the Carnot cycle , is equal to zero, because the material of the working body has the special properties

Constant-volume calorimetry is calorimetry performed at a constant volume. This involves the use of a constant-volume calorimeter.

No work is performed in constant-volume calorimetry, so the heat measured equals the change in internal energy of the system. The heat capacity at constant volume is assumed to be independent of temperature.

Heat is measured by the principle of calorimetry.

Heat is measured by the principle of calorimetry.

q = C V Δ T = Δ U , {\displaystyle q=C_{V}\Delta T=\Delta U\,,} ${\displaystyle q=C_{V}\Delta T=\Delta U\,,}$

where

ΔU is change in internal energy,

ΔT is change in temperature and

C_V is the heat capacity at constant volume.

i hope it will be clear to you by above . i am able to clear ur doubt and help you..
