I need help answering this calorimetry problem. Is the answer 293K or 20 degrees Celsius?

The table presents the specific heat capacities of various materials, expressed in joules per kilogram per degree Celsius (J/(kg·°C)), which is a measure of how much heat energy is required to raise the temperature of one kilogram of a substance by one degree Celsius.

**Table: Specific Heat Capacities of Selected Materials**

| Material       | Specific Heat in J/(kg·°C) |
|-----------------|-----------------------------|
| Aluminum       | 920                         |
| Copper         | 390                         |
| Water (at 15°C) | 4186                        |
| Lead            | 130                         |
| Iron or Steel   | 460                         |

**Explanation of Table Contents:**

- **Aluminum**: Has a specific heat capacity of 920 J/(kg·°C). This indicates it requires 920 joules of energy to raise the temperature of one kilogram of aluminum by one degree Celsius.
  
- **Copper**: With a specific heat capacity of 390 J/(kg·°C), copper requires less energy than aluminum for the same temperature rise.
  
- **Water (at 15°C)**: Water has a high specific heat capacity of 4186 J/(kg·°C), meaning it can absorb a lot of heat before its temperature changes significantly. This property makes water an effective coolant.
  
- **Lead**: Exhibits a low specific heat capacity of 130 J/(kg·°C), indicating it heats up and cools down quickly with less energy involved compared to the other materials listed.
  
- **Iron or Steel**: These materials have a specific heat capacity of 460 J/(kg·°C), higher than copper and lead but lower than aluminum and water.

Understanding the specific heat capacities of materials is crucial in various applications, such as material selection in engineering and designing thermal systems.
