4. Predicting What would have happened, in terms of thermal energy transfer, if the water temperature had originally been10.0°C? Explain your reasoning.
Context:Background InformationThe quantity of energy transferred by heat from a body depends on anumber of physical properties of the body and its surroundings. For a given substance, the rate at which thermal energy is transferred by conduction depends on temperature difference, cross-sectional area, and a thermal conductivity constant that is unique to the substance. By choosing one of these properties as a manipulated variable and making the other properties controlled variables, the effect of the manipulated variable on thermal conduction can be determined experimentally. In this investigation, you will study the rates of cooling of three containers of water of equal volume but different surface area.

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.
