The boiling point of __________ is -`10.5^circ`C.

Two long parallel surfaces each of emissivity 0.7 are maintained at
different temperatures and accordingly have radiation heat exchange
between them. It is desired to reduce 75% of the radiant heat transfer
by inserting thin parallel shields of emissivity 1 on both sides. The
number of shields should be
