9. As part of a lab experiment, Tasha drops a metal cube into a beaker of 2 points water as shown in the figure below. After the energy in the form of heat transfers between the substances, what is the final temperature of the water? A. The final temperature is 25^circ C because there is more water than metal. B. The final temperature is 50^circ C because the metal warms the water to the temperature of the metal. C. The final temperature is between 25^circ C and 50^circ C because energy is transferred from the metal to the water. D. The final temperature is between 25^circ C and 50^circ C because most of the thermal energy is lost to the air around the substances.

Answer 1

To determine the final temperature of the water after a metal cube is dropped into it, we need to consider the principles of heat transfer. When two substances at different temperatures come into contact, heat will flow from the hotter substance to the cooler one until thermal equilibrium is reached, meaning both substances will have the same final temperature.The question does not provide the initial temperature of the metal cube, but it does provide four possible answers. Let's evaluate each option:A. The final temperature is

because there is more water than metal.- This option suggests that the mass of the water is enough to prevent any change in temperature. However, regardless of the mass difference, some amount of heat transfer will occur, and the final temperature will be affected unless the metal cube is also at

.B. The final temperature is

because the metal warms the water to the temperature of the metal.- This option assumes that the metal is at

and that it has enough thermal energy to raise the temperature of the water to

. Without knowing the specific heat capacities and masses of the metal and water, we cannot conclude that the water will reach

.C. The final temperature is between

and

because energy is transferred from the metal to the water.- This option is plausible if we assume the metal is initially at a temperature higher than

. Heat will transfer from the metal to the water until equilibrium is reached, resulting in a final temperature somewhere between the initial temperatures of the two substances.D. The final temperature is between

and

because most of the thermal energy is lost to the air around the substances.- While some thermal energy will indeed be lost to the surrounding air, it is unlikely that "most" of the thermal energy will be lost unless the system is left for a very long time or the conditions are such that heat loss is extremely rapid. This option does not accurately describe the typical outcome of such an experiment.Given the information provided and the principles of heat transfer, the most likely correct answer is:C. The final temperature is between

and

because energy is transferred from the metal to the water.Final Answer: C
