Question

physical properties
table with substances: mercury (liquid, silver/white, 39, 357), bromine (liquid, red - brown, -7, 59), water (liquid, colorless, 0, 100), sulfur (solid, yellow, 115, 445), sodium chloride (solid, white, 801, 1413), gold (solid, yellow, 1064, 2856), copper (solid, red - yellow, 1084, 2562)
multiple - choice question
if the colorless liquid freezes, then that would mean it would possibly be...
water
ethanal

Explanation:

From the table, water is a colorless liquid with a freezing point of 0°C. When a colorless liquid freezes, water is a common colorless liquid that freezes (turns to ice) at 0°C, matching the properties. Ethanol (ethanal might be a typo, likely ethanol) has a different freezing point (-114°C approximately, and from the table's context, water's freezing point is 0 which aligns with freezing of a colorless liquid here).

Answer:

water (assuming the options are water and ethanol/ethanal, and based on the table's data where water is colorless liquid with freezing point 0, so when it freezes, it's water)
