Question

You are a scientist conducting an experiment on energy transfers. During the reaction you measure a large transfer of heat energy. What units should you record them in? A. Joules B. Degrees Celsius C. Volts D. Degrees Kelvin

Answer 1

Answer:

Joules

Explanation:

The another ones are units of tempeture (B and D) and unit of electricity that relatione energy and charge. In chemistry the energy es measured in Joules, because the energy is  work done on an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre. In other words, J=Nm

Answer 2

Answer:

Option A is true

Explanation:

When you are a scientist conducting an experiment on energy transfer .

The reaction in which you measure a large amount of heat energy transfer.

We have to find the units which you should record them in

Energy: It is defined as the capability of doing the work .

When current I is flowing in ampere A  V is potential in volt  v applied  in the experiment  and R be resistance  in ohm used in experiment for time t in seconds

Then, heat energy =$VI$=A-volt=Joule

Heat energy=$I^2Rt$

Heat energy=$A^2ohm sec$=Joule

The S.I unit of heat energy is Joules.

Hence, option A is true.
