Temperature and heat are not :-

The temperature and heat are ___________ quantities.

Assetion : A refrigerator transfers heat from a lower temperature to a higher temperature. Reason: Heat cannot flow from a lower temperature to a higher temperature.

Assertion: Nitrogen is unreactive at room temperature but becomes reactive at elevated temperature (on heating or in the presence of catalysts). Reason: In nitrogen molecule, there is extensive delocalisation of electrons.

Assertion : Nitrogen in inactive at room temperature but becomes reactive at elevated temperature (on heating or in the presence of catalyst). Reason : In nitrogen molecule, there is delocalization electrons.
