A calorimeter is a device used for calorimetry, the science of measuring the heat of chemical reactions or physical changes as well as heat capacity. The word calorimeter is derived from the Latin word calor, meaning heat. Differential Scanning Calorimeters, Isothermal Microcalorimeters, Titration Calorimeters and Accelerated Rate Calorimeters are among the most uncommon types.
A spectrophotometer is a photometer (a device for measuring light intensity) that can measure intensity as a function of the color, or more specifically, the wavelength of light. There are many kinds of spectrophotometers. Among the most important distinctions used to classify them are the wavelengths they work with, the measurement techniques they use, how they acquire a spectrum, and the sources of intensity variation they are designed to measure. Other important features of spectrophotometers include the spectral bandwidth and linear range.
Perhaps the most common application of spectrophotometers is the measurement of light absorption, but they can be designed to measure diffuse or specular reflectance. Strictly, even the emission half of a luminescence instrument is a kind of spectrophotometer.

What is difference between photospectrometry and spectrophotometry?
There is no such thing as photospectrometry. It's sometimes used when actually meaning spectrophotometry. This usage is incorrect.
What is the relationship between heat and calorimetry?
heat is a form of energy. where as "calorimetry" is the study of energy or study of heat. calorimetry not only deals with heat but also with other forms of energy.
What is the difference between direct and indirect calorimetry?
Direct calorimetry is a direct measure of heat production, whereas indirect calorimetry is a measure of O2 consumption and CO2 production. Direct calorimetry is usually performed using a bomb calorimeter, where food is burned in a sealed container and the amount of heat produced is then converted into the number of calories that the food contains. The same process can be used to determine someone metabolic activities. By having someone sit in a sealed chamber and determine the amount of heat produced by their body. The heat produced can be converted to the number of calories burned. Indirect calorimetry can be applied to individuals as well. For example, by having someone exercise while attached to a metabolic cart, you can measure their exact oxygen consumption and carbon dioxide production. You can then measure how much oxygen the individual used as fuel. This calculation should give an accurate representation of their energy expenditure. Indirect calorimetry is used much more often than direct calorimetry in terms of determining energy expenditure for individuals because it is much cheeper and easier to administer.
On what principle does calorimetry depends?
law of conservation of energy.
What is an example that shows that the combustion of methane produces 802 kJmol of energy?
The enthalpy of combustion is determined by calorimetry.

Difference between spectrophotometry and differential spectrophotometry?
Differential spectrophotometry is a spectrophotometric analytical technique in which a solution of the sample's major component is placed in the reference cell and the recorded spectrum represents the difference between the sample cell and the reference cell...basically it uses major component of system as reference and NOT solvent ..for example if a enzyme ligand system is to be assayed ..enzyme + solvent is reference and enzyme + ligand + solvent is test sample..its for quantitative detection.

Does calorimetry measure alcohol intake?
calorimetry=amount of calories you intake, not alcohol

What is atomic spectrophotometry?
spectrophotometry is a branch of spectroscopy dealing with measurement of radiant energy transmitted or reflected by a body as function of wave lenght %
