Thermal Conductivity Consider a compound slab consisting of two different materials having equal thicknesses and thermal conductivities K and 2K, respectively. The equivalent thermal conductivity of the slab is Ruhul Amin Alig
Thermal Conductivity Two rods A and B of different materials are welded together as shown in figure.Their thermal conductivities are K1 and K2. The thermal conductivity of the composite rod will be Ruhul Amin Alig
Thermal Conductivity The unit of thermal conductivity is (a) W m–1 K–1 (b) J m K–1 (c) J m–1 K–1 (d) W m K–1 (NEET 2019) Ruhul Amin Alig
Thermal Conductivity A ‘thermacole’ icebox is a cheap and an efficient method for storing small quantities of cooked food in summer in particular. A cubical icebox of side 30 cm has a thickness of 5.0 cm. If 4.0 kg of ice is put in the box, estimate the amount of ice remaining after 6 h. The outside temperature is 45 °C, and co-efficient of thermal conductivity of thermacole is 0.01 J s–1 m–1 K–1. [Heat of fusion of water = 335 × 103 J kg–1] Ruhul Amin Alig
