### Consider the Table

The following table provides data on the triple points and normal melting points of three solids: A, B, and C.

| Solid | Triple Point (atm, °C) | Normal Melting Point (°C) |
|-------|-------------------|-----------------------------|
| A     | 0.91 atm, 124 °C | 108 °C                      |
| B     | 0.35 atm, –17 °C | 50 °C                       |
| C     | 0.0072 atm, 88 °C | 89 °C                       |

### Question

Based on the data in the table, which solids will melt under applied pressure?

### Answer

- ✔️ **C**
- ❌ B
- ✔️ **A**

### Explanation

The triple point is the condition under which all three phases of a substance (solid, liquid, and gas) coexist in equilibrium. A solid will melt under applied pressure if the applied pressure exceeds the triple point pressure and the temperature is above the normal melting point. Based on the given data, solids C and A meet these conditions under the specified pressures and temperatures.
