How does the resistance depend upon the temperature?

True or False plants moderate the temperature.

Why surface tension decreases with increase in temperature ?

Electrical conductance of metals decreases with increase in temperature.

True or false: Electrolytic conductance generally decreases with rise in temperature.

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : The resistivity of a semiconductor increases with temperature Reason: The atoms of a semiconductor vibrate with larger amplitude at higher temperatures there by increasing its resistivity

True or false: Metallic conductance decreases with increase in temperature.

True or false The solubilities of all ionic substances increase with increase of temperature.

True or False : Physical adsorption increases with rise in temperature whereas chemical adsorption decreases with rise in temperature.
