WebFeb 27, 2024 · The calorimeter is a device used to measure the change in temperature of a quantity of substance (usually water) of known specific heat. This change in temperature is due to the heat absorbed or released in the process being studied; chemical if it is a reaction, or physical if it consists of a phase or state change. WebJan 21, 2024 · The techniques of calorimetry can be used to measure q for a chemical reaction directly. The enthalpy change for a chemical reaction is of significant interest to chemists. An exothermic reaction will release heat ( qreaction < 0, qsurroundings > 0) causing the temperature of the surrounding to increase.

WebOpen calorimeters are described in ISO 24473.35 In this type of test the product is placed under a calorimeter hood and the fire effluents are collected by the hood, which makes measurement of toxic gases possible.
