To determine which liquids have a freezing point lower than -50 degrees Fahrenheit, we need to convert -50°F to Celsius. The formula for this conversion is:
\[
C = (F - 32) \times \frac{5}{9}
\]
Calculating it:
\[
C = (-50 - 32) \times \frac{5}{9} = -82.22°C
\]
Now, let's look at the freezing points of the substances you’ve listed:
1. **Chloroform**: Freezing point is approximately -63.5°C (which is lower than -82.2°C or -50°F).
2. **Mercury**: Freezing point is approximately -38.83°C (which is higher than -82.2°C or -50°F).
3. **Turpentine**: Freezing point is approximately -74.2°C (which is also lower than -82.2°C or -50°F).
So, the liquids with a freezing point lower than -50°F (or -82.2°C) are **chloroform** and **turpentine**.
\[
C = (F - 32) \times \frac{5}{9}
\]
Calculating it:
\[
C = (-50 - 32) \times \frac{5}{9} = -82.22°C
\]
Now, let's look at the freezing points of the substances you’ve listed:
1. **Chloroform**: Freezing point is approximately -63.5°C (which is lower than -82.2°C or -50°F).
2. **Mercury**: Freezing point is approximately -38.83°C (which is higher than -82.2°C or -50°F).
3. **Turpentine**: Freezing point is approximately -74.2°C (which is also lower than -82.2°C or -50°F).
So, the liquids with a freezing point lower than -50°F (or -82.2°C) are **chloroform** and **turpentine**.
