Liquid nitrogen is used to make

A special kind of metal, liquid in nature is used to make thermometer and fluroscent bulb. Name it.

Assertion (A) : Liquid nitrogen is used in cryopreservation techniques. Reason (R ) : Gene bank DNA bank are the parts of germplasm conservation.

What is liquid nitrogen used for ?

A liquid-nitrogen container is made of a 1-cm thick styrofoam sheet having thermal conductivity 0.025Js^(-1)m^(-1) ^(@)C^(1) . Liquid nitrogen at 80K is kept in it. A total area of 0.80m^(-2) is in contcet with the liquid nitrogen. The atmospheric temperature is 300K . Calculate the rate of heat flow from the atmosphere to the liquid nitrogen.
