Water is being boiled in a flat bottomed kettle placed on a stove. The area of the bottom is 300 cm2 and the thickness is 2 mm. If the amount of steam produced is 1g min–1, then the difference of the temperature between the inner and the outer surface of the bottom is : (thermal conductivity of the material of the kettle = 0.5 cal–cm–1 °C–1 S–1 and latent heat of the steam is equal to 540 cal g–1)
- 12°C
- 1.2°C
- 0.2°C
- 0.012°C
Answer
(D) 0.012°C
