How do you measure calorimetry?

Question

Cameron Andrews · Accepted Answer

Calorimetry is the measurement of heat flow.

Heat energy flows from a substance that has a higher temperature to a substance that has a lower temperature. The heat will continue to flow until both substances reach the same temperature, known as the final temperature.

A device called a calorimeter is used to measure heat flow. It consists of nested styrofoam cups. In a high school chemistry class we generally study the heat exchange between hot metals and water or water samples at different temperatures. The nested styrofoam cups are insulators so that all the heat is transferred from the warm object to the cooler one.

The equation for heat, q = m x #C_s# x #deltaT# is used for calorimetry. The heat lost by the warm object is equal to the heat gained by the cooler object:
Q lost by the hot material = Q gained by the cold material
We can set up the following equation to solve for any part of the heat calculations
[ Mhot x #C_s#hot x (#T_f# - #T_bhot)] - [Mcold x C_s# cold x (#T_f# -#T_b#cold)] = 0

#C_s# is the specific heat of the material. M is mass and T is temperature.

undefined Calorimetry is measured by using a calorimeter, which is a device designed to measure the heat absorbed or released during a chemical or physical process. The change in temperature of a substance within the calorimeter is measured using a thermometer, and the amount of heat transferred is calculated using the equation Q = mcΔT, where Q is the heat transferred, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
