To determine the state of chloroform at the given temperatures, we need to know the phase transition points of chloroform. According to the phase diagram:
- Below -63.5 °C, chloroform is a solid.
- Between -63.5 °C and 61.7 °C, chloroform is a liquid.
- Above 61.7 °C, chloroform is a gas.
Let's classify each temperature:
1. -48 °C:
- This temperature is between -63.5 °C and 61.7 °C.
- Therefore, chloroform at -48 °C is a Liquid.
2. 32 °C:
- This temperature is also between -63.5 °C and 61.7 °C.
- Therefore, chloroform at 32 °C is a Liquid.
3. -149 °C:
- This temperature is below -63.5 °C.
- Therefore, chloroform at -149 °C is a Solid.
4. 84 °C:
- This temperature is above 61.7 °C.
- Therefore, chloroform at 84 °C is a Gas.
So the states can be categorized as follows:
- Solid: -149 °C
- Liquid: -48 °C, 32 °C
- Gas: 84 °C
