Question

In a popular lecture demonstration, a sheet of paper is wrapped
around a rod that is made from wood on one half and metal on the other half. If
held over a flame, the paper on one half of the rod is burned while the paper on
the other half is unaffected. Is the burned paper on the wooden half of the
rod, or on the metal half of the rod?

Hector read that the traditional drink in Tibet is tea with added butter. Inspired by this idea, he decides to investigate how a thin layer of fat on the top of a hot liquid affects the cooling of the liquid. He performs two different experiments.Experiment 1: Hector pours 100 mlml of boiling water into each of two Styrofoam cups and adds a thin (2.0-mmmm) layer of hot oil (at about 100∘C∘C ) to one of the cups. He measures the initial temperature in the cups, waits for 10 minutes, and then measures the temperature again. His measurements are shown below. Cup A(no oil) Cup B(with layer of oil) TiTi 98∘C∘C 98∘C∘C TfTf 84∘C∘C 95∘C∘C Experiment 2: Hector puts two empty Styrofoam cups on separate precision scales and zeroes the scales. Then he pours 100 mlml of boiling water into each cup and adds a 2.0-mmmm layer of hot oil to one of the cups. He records the initial readings of the scales, waits for 10 minutes, and then records the readings of the scales again. His data…
A copper rod of length 0.500 m and cross-sectional area 8.60 × 10−2 cm2 is connected to an iron rod with the same cross section and length 0.250 m. One end of the copper is immersed in boiling water and the other end is at the junction with the iron. If the far end of the iron rod is in an ice bath at 0°C, find the rate of heat transfer passing from the boiling water to the ice bath. Assume there is no heat loss to the surrounding air. The thermal conductivity of copper is 401 W/m·K and iron is 80.2 W/m·K. in W
The specific heat of a certain steel is0.46 J·g−1·K−1 and the specific heat of a “dry” wood is 1.8 J·g−1·K−1. Suppose we add a given amount of energy as heat to 10.0-gram samples of the steel and wood. (a) Which sample will undergo the largest temperature increase? (b) Calculate the ratio of the temperature increase for the two samples. answer: (a) steel, (b) 3.9 = steel/wood
