Passage
Students conducted an experiment to determine the insulating properties of certain materials. In each trial, “blankets” made of different materials of different thicknesses were wrapped around an aluminum capsule ﬁlled with 0.250 L of water at a known initial temperature, Ti , and placed into an oven preheated to a certain temperature.
Heat was transferred through the insulating materials from the oven to the water inside the capsule. After 5 minutes, the temperature of the water inside the capsule, T_f , was recorded. The heat ﬂow, measured in joules per second (J/s), is shown in Table 1. (Note: In each trial, the same size and shape of aluminum capsule were used. One trial was done with no insulation around the aluminum capsule.)

Q. Trials 3 and 5 provide evidence that heat ﬂow depends on which of the following factors?

a)
Type of insulating material.
b)
Temperature of oven.
c)
Contact area.
d)
Thickness of insulating material.

Correct answer is option 'D'. Can you explain this answer?

Trials 3 and 5 both had the same insulation material, initial temperature, and oven temperature; however, they had different heat ﬂows. The only condition that was varied between the two trials was the thickness of the insulator. This suggests that heat ﬂow depends on the thickness of the insulating material, answer choice D.

Directions:Read the passages and choose the best answer to each question.PassageNear the end of the 19th century, British engineer Osborne Reynolds ran a set of experiments to observe and predict the transition between laminar (steady) and turbulent ﬂow of a liquid through a pipe. In Reynolds’ experiments, dye was forced through a liquid to show visually when the ﬂow changed from laminar to turbulent. Laminar ﬂow is common only in cases in which the ﬂow channel is relatively small, the ﬂuid is moving slowly, and its viscosity (the degree to which a ﬂuid resists ﬂow under an applied forc e) is relatively high. In turbulent ﬂow, the speed of the ﬂuid at any given point is continuously undergoing changes in both magnitude and direction. Reynolds demonstrated that the transition from laminar to turbulent ﬂow in a pipe depends upon the value of a mathematical quantity equal to the velocity of ﬂow (V ) times the diameter of the tube (D) times the mass density (ρ) of the ﬂuid divided by its absolute viscosity (µ). The “Reynolds number,” as it is called, is determined by the following equation:Several students designed similar experiments to observe ﬂow rates of different liquids. To conduct the experiments, the students were given the following apparatus: Liquid supply tank with clear test section tube and ‘bell mouth’ entrance 1 Rotameter to measure the velocity of ﬂow (ﬂow rate) Tap water • Motor oil 4, 10-ft long smooth pipes of various diameters: 0.25-inch, 0.50-inch, 0.75-inch, 1.0-inchFigure 1 illustrates an approximation of the set-up of each experiment.Figure 2 shows approximate viscosities of the water and motor oils used in the experiments.Experiment 1In Experiment 1, students began with a pipe of diameter 0.25 inches. The pipe was set first at a 15° angle and tap water was released steadily from the tank into the pipe. The velocity of flow (V) was measured. The pipe was then set at a 30° angle, a 45° angle, and a 60° angle, water was released steadily from the tank into the pipe, and the velocity of flow was measured. The process was then repeated for each diameter of pipe using the same amount of water each time. All data were recorded in Table 1. Temperature of the water was held constant at 20°C.Experiment 2In the second experiment, the tap water was replaced by Motor Oil A and the processes were repeated. The results are given in Table 2.Experiment 3In a third experiment, the tap water was replaced by Motor Oil B and the processes were repeated.Q.All of the experimental factors were identical EXCEPT
