students design an experiment with a curved insulated rod

Students design an experiment with a curved, insulated rod of an unknown thermally conducting material, as shown in the figure. The rod is 1 m long and 2 cm in diameter. One end of the rod is touching the surface of water kept at 350K by a hot plate, and the other end is just touching the surface of a well-insulated block of ice.

Sample: P2 Q2 A Score: 11. This response describes the experiment and analysis in part (a) thoroughly and earned full credit of 7 points for parts (a)(i) and (a)(ii). Part (b) earned only 2 points because the unit of volt is not included in the label on the vertical axis of the graph. Instead ∆V is written in parenthesis where the unit would ...

sink. Record your initial guess for the kind of material of which each rod is made based on visual inspection. 2. Measure the length of each rod and record their lengths L 1 in table 1. 3. Insert one of the rods in the jacket and tighten the sheath bolt at the upper left end of the support jacket to hold it in place.

I. Thermal Conductivity of Plexiglass. Construct a "sandwich" consisting of aluminum, masonite and plexiglass with the slots arranged so that thermocouples can be inserted on either side of the masonite plate. Place the sandwich on the hot plate with the aluminum side down. Place the ice bath on top of the sandwich.

1.2.9. Consider a thin one-dimensional rod without source of thermal energy whose lateral surface is not insulated. Let w(x;t) dente the heat energy °owing out of the lateral sides per unit surface area per unit time. Assume that w(x;t) is proportional to the temperature difierence between the rod u(x;t) and a known outside temperature °(x;t ...

Since the rod is insulated, there is no transfer of heat from the rod except at its two ends. We may therefore assume that the temperature u depends only on x and on the time t. 0 x L ∆ x Figure 1 The variation of temperature in an insulated rod. Consider a small section of the rod between x and x C 1 x. Let S be the cross-sectional area of ...

Suppose that the right-hand end of a rod is insulated. That means that no heat can flow out of that end to the right, nor can any heat flow into that end from the right. Any heat flowing into the segment from the left-hand side will be trapped, and simply raise the temperature of the segment. Let's look again at one small section of a metal rod.

LO: 1.E.3.1 The student is able to design an experiment and analyze data from it to examine thermal conductiv-ity. 5.B.6.1 The student is able to describe the models that represent processes by which energy can be transferred between a system and its environment because of differences in temperature: conduction, convection, and radiation.

Calculate the final temperature of the system, assuming no heat is lost to the surroundings. Use the following specific heats: 4190J/kg • C° (water), 470 J/kg • C° (iron), and 390 J/kg • C° (copper). 36C. Study with Quizlet and memorize flashcards containing terms like A thermally isolated system consists of a hot piece of aluminum and ...

Suppose a rod and it's ends are kept at different temperatures. At a particular point of the rod , in steady state, the heat going forward becomes equal to the heat coming from backward so temperature remains same.Although heat exchange continually happens from the that point to a cooler part but a hotter part is also giving that point heat.

Experimental Methods. Students designed an experiment to determine whether the relationship between two variables was more accurately described as linear or quadratic. Students had to realize they would need to perform trials with different values of the independent variable, rod thickness, to determine how thickness affects breaking force.

hat heat is transferred from warmer matter to cooler matter. Let'. examine the role the cup plays in the transfer of the heat. When the hot water is poured into the cu. the cup is a different tempera-ture than the hot chocolate. The diffe. ent temperatures set the stage for a heat transfer to occur. Doe. the material the coffee cup is made ...

A glass rod is rubbed with silk, and another glass rod is rubbed with wool. Next, a rubber rod is rubbed with silk, and another rubber rod is rubbed with wool. The rods are then brought close to, but do not touch, the two different electroscopes. The results of this experiment are shown in the table.

Students must engineer an insulated container to minimize heat loss according to a set of design and performance constraints; a temperature sensor is used to assess insulator performance. Supports NGSS Performance Expectations HS-PS3-3: Design, build, and refine a device that works within given constraints to convert one form of energy into ...

Holding the rod in one hand, rub it vigorously with the fur. This will produce a negative charge on the rubber rod. Do the same thing with the glass rod and silk cloth. A positive charge will be produced on the glass rod. Test each for charge by bringing the rod close to the electroscope.
