A 100g sample of a metal was heated to 100oC and then quickly transferred to an insulated container holding 100g of water at 22oC. The temperature of the water rose to reach a final temperature of 35oC. Which of the following can be concluded?
A) The metal temperature changed more than the water temperature did; therefore the metal
lost more thermal energy than the water gained.
B) The metal temperature changed more than the water temperature did, but the metal lost
the same amount of thermal energy as the water gained.
C) The metal temperature changed more than the water temperature did; therefore the heat
capacity of the metal must be greater than the heat capacity of the water.
D) The final temperature is less than the average starting temperature of the metal and the
water; therefore the total energy of the metal and water decreased.

Heat capacity or thermal capacity is defined as the amount of heat required by a given mass of a material to raise its temperature by one unit which means that the heat capacity of the water, that is the quantity of heat required to cause a rise from 22°C to 35°C that is a rise of 13°C is the quantity of heat that caused the drop in temperature of the metal from 100°C to 35°C a change of 65°C

The water has more capacity to absorb heat or a higher heat capacity than the metal

However, the first law of thermodynamics states that energy is neither created nor destroyed, but it changes from one form to another. In this case, the thermal energy lost by the metal is the same as the thermal or heat energy gained by the water

The branch of science which deals with chemicals and bonds is called chemistry.

The correct answer is B

Heat capacity or thermal capacity is defined as the amount of heat required by a given mass of a material to raise its temperature by one unit which means that the heat capacity of the water

The quantity of heat required to cause a rise from 22°C to 35°C that is a rise of 13°C is the quantity of heat that caused the drop in temperature of the metal from 100°C to 35°C a change of 65°C

The water has more capacity to absorb heat or a higher heat capacity than the metal because the water has more space in between the particles.

However, the first law of thermodynamics states that energy is neither created nor destroyed, but it can transform from one material to another material. The heat always flows from the high temperature to the low temperature.

Hence, the correct option is B that is The metal temperature changed more than the water temperature did, but the metal lost the same amount of thermal energy as the water gained.
