A 2020 lab study measured boiling point (°C) of four liquid mixtures at sea level: Mixture J, 78°C; Mixture K, 100°C; Mixture L, 118°C; Mixture M, 132°C. The lead chemist argued that of the four, Mixture J would evaporate most readily at room temperature. To support this, she could cite ______
Which choice most logically completes the text using the data above?
- A
the average boiling point across mixtures.
- Bcheck_circle
Mixture J's lowest boiling point of 78°C, requiring the least heat to vaporize.
- C
Mixture M's boiling point of 132°C.
- D
Mixture L's boiling point of 118°C.
Explanation
Lower boiling point means more volatile at room temperature. Choice B directly cites Mixture J's lowest boiling point, supporting the claim it would evaporate most readily.
