A 30.00-g sample of metal (X) was heated to 100.00°C. This sample was clamped in contact with a 40.00-g sample of a different metal (Y) originally at 25.00°C. The final temperature of the two metals was 37.30°C, and no heat was lost to the surroundings. What is one possible conclusion from this experiment?
A.
The heat lost by X was greater than the heat gained by the Y.
B.
The heat lost by X was equal to the heat gained by Y.
C.
The heat lost by X was less than the heat gained by Y.
D.
The final temperature was incorrectly determined, as it should be the average (62.50°C)
