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. At what point along it's length should a temperature of 200°C be maintained so that in steady state, the mass of ice melting be equal to that of the steam produced in the same interval of time. Assume that the whole system is insulated from the surroundings. Latent heat of fusion of ice and vaporisation of water are 80 cal/gm and 540 cal/gm respectively
Ice starts forming in lake with water at \[{{0}^{o}}C\] and when the atmospheric temperature is \[-{{10}^{o}}C\]. If the time taken for 1 cm of ice be 7 hours, then the time taken for the thickness of ice to change from 1 cm to 2 cm is [NCERT 1971; MP PMT/PET 1988; UPSEAT 1996]

One end of a metal rod of length 1.0 m and area of cross section \[100c{{m}^{2}}\] is maintained at \[{{100}^{o}}C.\]If the other end of the rod is maintained at \[{{0}^{o}}C\], the quantity of heat transmitted through the rod per minute is (Coefficient of thermal conductivity of material of rod =100W/m-K) [EAMCET (Engg.) 2000]

Two rods of same length and material transfer a given amount of heat in 12 seconds, when they are joined end to end. But when they are joined lengthwise, then they will transfer same heat in same conditions in [BHU 1998; UPSEAT 2002]
