Question

1. the table shows the freezing points for gases. order the gases from least to greatest according to their freezing points. (example 2)

gas	freezing points (°c)
carbon monoxide	$-205$
ethane	$-297$
helium	$-272$
oxygen	$-219$
sulfur dioxide	$-72$

Explanation:

Step1: List freezing points

Ethane (-297), Helium (-272), Oxygen (-219), Carbon Monoxide (-205), Argon (-189), Sulfur Dioxide (-72)

Step2: Order from least to greatest

Least (most negative) to greatest (least negative)

Answer:

Ethane, Helium, Oxygen, Carbon Monoxide, Argon, Sulfur Dioxide
