Question

the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer. which of the following statements provides the correct freezing and boiling points of water on the celsius and fahrenheit temperature scales? water boils at 100°c and 212°f. water freezes at 32°c and 0°f. water boils at 212°c and 100°f. water freezes at 0°c and 32°f. water freezes at 0°c and 32°f. water boils at 100°c and 212°f. water freezes at 32°c and 0°f. water boils at 100°c and 100°f.

Explanation:

To determine the correct freezing and boiling points of water in Celsius (°C) and Fahrenheit (°F) scales, we recall the standard values:

• Freezing point of water: \( 0^\circ \text{C} \) (Celsius) and \( 32^\circ \text{F} \) (Fahrenheit).
• Boiling point of water: \( 100^\circ \text{C} \) (Celsius) and \( 212^\circ \text{F} \) (Fahrenheit).

Now we analyze each option:

• First option: Incorrect freezing points (32°C and 0°F are wrong; freezing is 0°C and 32°F).
• Second option: Incorrect boiling points (212°C and 100°F are wrong; boiling is 100°C and 212°F).
• Third option: Matches the correct freezing (\( 0^\circ \text{C}, 32^\circ \text{F} \)) and boiling (\( 100^\circ \text{C}, 212^\circ \text{F} \)) points.
• Fourth option: Incorrect freezing (32°C) and boiling (100°F) points.

Answer:

C. Water freezes at \( 0^\circ \text{C} \) and \( 32^\circ \text{F} \). Water boils at \( 100^\circ \text{C} \) and \( 212^\circ \text{F} \) (assuming the third option is labeled as C; if the original options had labels like A, B, C, D with the third being C, this is the correct one).
