a) A brass rod of length 2L and a steel rod of length L have the same cross-sectional area are attached end to end as shown in the figure. The brass end is placed in a boiling water which is maintained at a constant temperature of 100 °C. The steel end is placed in an ice bath held at constant temperature of 0.0 °C. The system is in a steady state. Calculate the temperature T at the point where the two rods are joined. Ksteel =50.2 W/m-K_and_kbrass =109 W/m-K [Answer in 3 significant figures] 0°C Steel L T 100°C Brass 2L

A hollow aluminum cylinder 20.0 cm deep has an internal capacity of 2.000 L at 20.0C. It is completely filled with turpentine at 20.0C. The turpentine and the aluminum cylinder are then slowly warmed together to 80.0C. (a) How much turpentine overflows? (b) What is the volume of the turpentine remaining in the cylinder at 80.0C? (c) If the combination with this amount of turpentine is then cooled back to 20.0C, how far below the cylinders rim does the turpentines surface recede?

Consider an object with any one of the shapes displayed in Table 10.2. What is the percentage increase in the moment of inertia of the object when it is warmed from 0C to 100C if it is composed of (a) copper or (b) aluminum? Assume the average linear expansion coefficients shown in Table 16.1 do not vary between 0C and 100C. (c) Why are the answers for parts (a) and (b) the same for all the shapes?

What is me Fahrenheit temperature of a person with at 39.0°C fever?

(a) If a 500mL glass beaker is filled to the brim with ethyl alcohol at a temperature of 500C, how much will overflow when its temperature reaches 210C ? (b) How much less water would overflow under the same conditions?

(a) Estimate the specific heat capacity of sodium from the Law of Dulong and Petit. The molar mass of sodium is 23.0 g/mol. (b) What is the percent error of your estimate from the known value, 1230 J/kg ? `

(a) Use the ideal gas equation to estimate the temperature at which 1.00 kg of steam (molar mass M=18.0 g/mol) at a pressure of 1.50106 Pa occupies a volume of 0.220 m3. (b) The van der Waals constants for water are a=0.5537 Pa m6/mol2 and b=3.049105 m3/mol. Use the Van der Waals equation of state to estimate the temperature under the same conditions. (c) The actual temperature is 779 K. Which estimate is better? `

= As shown in the figure below, you have a system including a Iron cup with mass Mcup = 0.214 kg. The cup contains water with mass Mwater = 0.345 kg. Both the cup and water are initially at a temperature of 31.8 degrees Celsius. You drop ice into the system. The ice has an initial temperature of -51.0 degrees Celsius and a mass of Mice 1.1490 kg. The system will reach equilibrium with none the ice having melted, but some of the water having frozen at the final temperature of 0 degrees Celsius. ice ice Beryllium Cadmium Iron Lead water cup Find the mass of water frozen, mfrozen = Material c (J/(kg K)) Aluminum 897 1820 231 412 129 2303 466 116 ice Polyethylene Steel Uranium None of the ice melts.
