the measurement of energy that is given off or absorbed in a physical or chemical process

Explanation: Calorimetry is the process of measuring the amount of heat released or absorbed during a chemical reaction.

It can be found whether a reaction is exothermic or endothermic by knowing the change in heat. This is done by the use of device called calorimeter.

Exothermic reactions are accompanied by release of heat whereas endothermic reactions are accompanied by absorption of heat. Thus by knowing the temperature changes, we get to know whether the heat has been released or absorbed.

Answer from: kmwilliams9019

The statement that defines calorimetry is the measurement of energy that is given off or absorbed in a physical or chemical process.

The correct statement is C.

What is calorimetry?

Calorimetry is the study or act of determining changes in a body's state variables.

Calorimetry is the science of measuring the heat exchanged with the environment to determine the changes in energy of a system.

Thus, statement C is correct.

Answer from: Quest

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.
