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. WebIndirect calorimetry can be open or closed. In the open type, which is the most common, a mask or hood or animal chamber may be used. Air intake and carbon dioxide and methane output are precisely measured. Automated gas analysis and computer control make it much easier to handle air intake and CO2 output. These types of machines are common in use. church lane cottage cley https://brain4more.com
