A body cools in a surrounding which is at a constant temperature of \[{{\theta }_{0}}\]. Assume that it obeys Newton's law of cooling. Its temperature \[\theta \] is plotted against time t. Tangents are drawn to the curve at the points \[P(\theta ={{\theta }_{1}})\] and \[Q(\theta ={{\theta }_{2}})\]. These tangents meet the time axis at angles of \[{{\varphi }_{2}}\]and \[{{\varphi }_{1}}\], as shown
A composite metal bar of uniform section is made up of length 25 cm of copper, 10 cm of nickel and 15 cm of aluminium. Each part being in perfect thermal contact with the adjoining part. The copper end of the composite rod is maintained at \[{{100}^{o}}C\] and the aluminium end at \[{{0}^{o}}C\]. The whole rod is covered with belt so that there is no heat loss occurs at the sides. If \[{{K}_{\text{Cu}}}=2{{K}_{Al}}\] and \[{{K}_{Al}}=3{{K}_{\text{Ni}}}\], then what will be the temperatures of \[Cu-Ni\] and \[Ni-Al\] junctions respectively
One end of a copper rod of uniform cross-section and of length 3.1 m is kept in contact with ice and the other end with water at 100°C.
