Answer:

The procedure with the  simple calorimeter to  compare the energy released  by different fuels is described below in detail.

Explanation:

If the response delivers heat (rxn < 0), then heat is consumed by the calorimeter (calorimeter > 0), and its temperature improves. Conversely, if the response consumes heat (rxn > 0), suddenly heat is carried from the calorimeter to the arrangement (calorimeter < 0), and the temperature of the calorimeter drops.

Identify the highest energy molecular process that occurs when a molecule absorbs a microwave photon.
ElenaW [278]

The question is incomplete, the complete question is;

Identify the highest energy molecular process that occurs when a molecule absorbs a microwave photon

a) electronic excitation

b) bond breakage

c) molecular vibration

d) molecular rotation

Answer:

molecular rotation

Explanation:

Microwaves are part of the electromagnetic spectrum. They are lower energy, lower frequency radiation.

When molecules absorb infrared radiation, they transition between the rotational states of the molecule.

Hence, the highest energy molecular process that occurs when a molecule absorbs a microwave photon is molecular rotation.
