Researchers have now been able to cool substances to absolute zero.
a. true
b. false

The correct option is B) false.

Explanation:

Absolute zero is the point where it is not feasible to cool further.

The lowest possible temperature is 0 kelvin which is also known as absolute zero. In degrees its corresponds to –273.15 degrees Celsius.

it is not possible to reach or cool a substance to absolute zero although nearby temperatures can be reached.

Consider the provided statement.

Researchers have now been able to cool substances to absolute zero is a false statement.

The correct option is B) false.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
