Liquid oxygen freezes at `- 218.4 ^(@)C` and boils at `- 183^(@)C`. Express these temperatures in Fahrenheit scale.

Explanation

To convert the temperatures of liquid oxygen from Celsius to Fahrenheit, we can use the formula:

\[ F = \frac{9}{5}C + 32 \]

where \( F \) is the temperature in Fahrenheit and \( C \) is the temperature in Celsius.

### Step 1: Convert -218.4 °C to Fahrenheit

1. **Substitute -218.4 for C in the formula**:
\[ F = \frac{9}{5}(-218.4) + 32 \]

2. **Calculate \(\frac{9}{5} \times -218.4\)**:
\[ \frac{9}{5} \times -218.4 = -392.112 \]

3. **Add 32 to the result**:
\[ F = -392.112 + 32 = -360.112 \]

Thus, the freezing point of liquid oxygen in Fahrenheit is approximately:
\[ F \approx -360.112 \, °F \]

### Step 2: Convert -183 °C to Fahrenheit

1. **Substitute -183 for C in the formula**:
\[ F = \frac{9}{5}(-183) + 32 \]

2. **Calculate \(\frac{9}{5} \times -183\)**:
\[ \frac{9}{5} \times -183 = -329.4 \]

3. **Add 32 to the result**:
\[ F = -329.4 + 32 = -297.4 \]

Thus, the boiling point of liquid oxygen in Fahrenheit is approximately:
\[ F \approx -297.4 \, °F \]

### Final Answer:
- The freezing point of liquid oxygen is approximately **-360.112 °F**.
- The boiling point of liquid oxygen is approximately **-297.4 °F**.
