HELP !!!!!!!

A metal sample is heated and placed into the water in a calorimeter at room temperature. Which statement best describes how the calorimeter can be used to determine the specific heat capacity of the metal sample?
Energy transfers to the metal from the water and calorimeter until they are all at room temperature
. Energy transfers from the metal to the water and calorimeter until they are all at room temperature.
Energy transfers to the metal from the water and calorimeter until they all reach a single temperature.
Energy transfers from the metal to the water and calorimeter until they all reach a single temperature.

Answer 1

Energy transfers from the metal to the water and calorimeter until they all reach a single temperature.

Step-by-step explanation:

Both the water and the metal must undergo a change in energy, however because of the law of conservation of energy, it is not possible for the metal and the water to return to room temperature if the water was initially at room temperature. (You can also use the q = s • m • ΔT equation to reason it out)
