Single Choice

While measuring the thermal conductivity of liquids, the upper part is kept hot and lower one cool so that :

Aconvectional flow is stopped
Correct Answer
Bradiation is stopped
Cconduction is easier
Dit is easier to perform the experiment

Solution

Heat flows from hotter part to colder part and the above arrangement is done to avoid convection currents.
