A 100-g sample of an unknown metal at 100,^circC is placed in 100 g of water at 20,^circC. The final equilibrium temperature of the mixture is 25,^circC.
Which of the following is true regarding the specific heat capacity of the metal compared to water?
- The metal has a negative specific heat because it lost energy.
- The metal's specific heat is higher than that of water because it started at a higher temperature.
- The metal's specific heat is significantly lower than that of water.
- The specific heats are equal because the final temperature is between the two starting temperatures.
