law of conservation of energy.

∙ 12y ago
Calorimetry depends on the principle of conservation of energy, which states that energy can neither be created nor destroyed, only transferred or converted from one form to another. In calorimetry, heat absorbed or released during a chemical reaction is measured to determine the change in energy of the system.

What is the relationship between heat and calorimetry?
Calorimetry is the scientific measurement of heat transfer during physical or chemical processes. It involves measuring the heat absorbed or released by a substance through temperature changes. Calorimetry is used to study the energetics of reactions and determine the specific heat capacity of substances.
How does direct calorimetry and indirect calorimetry work?
Direct calorimetry measures energy expenditure by directly assessing heat production using a calorimeter. Indirect calorimetry estimates energy expenditure by measuring oxygen consumption and carbon dioxide production, which are then used to calculate energy expenditure based on known respiratory exchange ratios and energy equivalents of oxygen and carbon dioxide.
What is the difference between direct and indirect calorimetry?
Direct calorimetry measures heat production using a calorimeter, while indirect calorimetry estimates energy expenditure by measuring oxygen consumption and carbon dioxide production. Direct calorimetry is more accurate but less practical, while indirect calorimetry is widely used in clinical and research settings.
What is an example that shows that the combustion of methane produces 802 kJmol of energy?
The enthalpy of combustion is determined by calorimetry.
How is calorimetry related to the law of conservation of energy?
Calorimetry is the science of measuring heat changes in a system. It is related to the law of conservation of energy because it is based on the principle that energy cannot be created or destroyed in a closed system, only transferred as heat. Calorimetry allows us to measure these energy transfers through heat flow in chemical reactions or physical changes.
What are the principles of calorimetry?
Isothermal Principle: total heat elimination = heat loss by radiation + convection + conduction + evaporation
Does calorimetry measure alcohol intake?
calorimetry=amount of calories you intake, not alcohol
What is a calorimetry?
A calorimetry is a wide headband which covers the ears, suitable for wearing on cold days.

How do you solve calorimetry problems?
To solve calorimetry problems, you need to know the specific heat capacity of the substances involved and the change in temperature that occurs during the reaction or process. Use the formula q = mcΔT, where q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature. Calculate the heat energy transferred to or from the system to solve the problem.
