AP Physics 2
9.5 Specific Heat and Thermal Conductivity
9.3 Thermal Energy Transfer and Equilibrium
Three solid metal blocks, labeled X, Y, and Z, are placed in direct thermal contact inside an insulated container of negligible heat capacity. The properties of each block are given in the table.
Assuming no thermal energy is exchanged with the surroundings, what is the final equilibrium temperature of the three-block system?
| Block | Mass (kg) | Specific Heat Capacity (J/(kg·°C)) | Initial Temperature (°C) |
|---|---|---|---|
| X | 1.0 | 400 | 100 |
| Y | 2.0 | 200 | 40 |
| Z | 1.0 | 800 | 20 |
