- At what rate is heat lost through a 1.3 m x 2.7 m rectangular glass window that is 0.32 cmthick when the inside surface temperature of the glass is 22°C and the outside surface temperatureof the glass is 16°C? The thermal conductivity of glass is 0.75 W/(m-K)[1m = 100 cm]Question 4If a copper kettle has a base of thickness 2 mm and area 3 x 10^-2 m², estimate the steady difference in temperature between inner and outer surfaces of the base which must be maintained to enable enough heat to pass through so that the temperature of 1 kg of water rises at the rate of 0.25 K s^-1. Assume that there are no heat losses, the thermal conductivity of copper = 380 Wm^-1K^-1. and the specific heat capacity of water is 4200 Jkg^-1 K^-1.To treat a burn on his hand, a person decides to place an ice cube on the burned skin. The mass of the ice cube is 16.8 g, and its initial temperature is -10.7 °C. The water resulting from the melted ice reaches the temperature of his skin, 29.4 'C. How much heat is absorbed by the ice cube and resulting water? Assume that all of the water remains in the hand. Constants for water can be found in this table.
