Try the solutions described in the attached picture, note the answers are marked with green colour.
Answer:
Substance A will release more heat.
Explanation:
Let suppose that both substances experiment an entirely sensible heat process and are incompressible and begin at the same temperature. Physically speaking, specific heat (
), measured in kilojoules per kilogram-degree Celsius, can be described by following expression:
(1)
Where:
- Released heat, measured in kilojoules.
- Sample mass, measured in kilograms.
,
- Initial and final temperatures of the sample, measured in degrees Celsius.
If we know that
,
,
and
, then we have the following inequation:


Substance A will release more heat.
Explanation:
K in chromatography is defined as a partition coefficient. It is an equilibrium constant that determines the measure to which the solutes partition between two phases.
K = Cm/Cs
where Cm is solute concentration in mobile phase
Cs is solute concentration in stationary phase
When K is more, then it implies that the solute concentration in the mobile phase is more in chromatography test.
The correct answer is option B
Load
Reason:
in any electrical circuits loads uses electricity. Some of the common examples of load are electrical appliances, lights etc
