stainless steel saucepan, with a base that is made of 0.540-cm-thick steel (κ = 46.0 W/(m·K)) fused to a 0.150 cm thickness of copper (κ = 401 W/(m·K)), sits on a ceramic heating element at 128°C. The diameter of the pan is 18.0 cm, and it contains boiling water at 100.00°C.   If the copper-clad bottom is touching the heat source, at what rate will the water evaporate from the pan? Latent heat of vaporization (Lv) for water is 2256 J/g. Enter your answer in three decimal points.

An aluminum bar has a cross-section that is 4.31 cm by 7.32 cm and is 2.38 m long. Aluminum has a thermal conductivity of 205 W/m K. If the aluminum bar is used to bridge between ice at 0 °C and boiling water at 100 °C, what is the rate of heat transfer (in W) along the bar?

A 0.0500-kg ice cube at −30.0°C is placed in 0.350 kg of 35.0°C water in a very well-insulated container. What is the final temperature in degrees Celsius?

A rod made of glass has a circular cross section with a diameter of 0.1200 m at a temperature of 20 degrees celsius. An aluminum ring has a diameter of 0.1196 m at a temperature of 20 degrees celsius. The coefficients of thermal expansion for glass and aluminum are 9.0 x 10-6 1/K and 24.0 x 10-6 1/K, respectively. At what temperature will the aluminum ring be able to slip over the glass rod? Between 225 and 250 degrees celsius Between 175 and 200 degrees celsius Between 100 and 125 degrees celsius Higher than 300 degrees celsius Between 250 and 275 degrees celsius Between 125 and 150 degrees celsius Between 275 and 300 degrees celsius Between 150 and 200 degrees celsius O Between 200 and 225 degrees celsius

A highway is made of concrete slabs that are 16.2 m long at 20.0°C. Expansion coefficient of concrete is α = 12.0 × 10−6 K−1. If the temperature range at the location of the highway is from −20.0°C to +36.9°C, how large are the gaps at −20.0°C? in mm

A pair of eyeglass frames are made of an epoxy plastic (coefficient of linear expansion = 1.30 10-4°C-1). At room temperature (20.0°C), the frames have circular lens holes 2.40 cm in radius. To what temperature must the frames be heated if lenses 2.41 cm in radius are to be inserted into them?
