Question

Explain the following 1. Dry ice sublimes

Answer 1

Answer:

Dry ice refers to Solid CO2.

It's main functions:

1. It acts as a cooling agent.

2. It prevents decomposition of preserved bodies.

3. It has a cooling temperature less than that of ice.

As per the question, the statement is

DRY ICE SUBLIMES:

Dry ice is formed from CO2 under very high pressure. Very high pressure makes CO2 to solid form.

Now, when the pressure is removed, the solid form is directly converted to gaseous form.

This type of conversion is called SUBLIMATION.

Answer 2

ExplainaTion:-

$\longrightarrow$One use for dry ice is in ice cream trucks. Dry ice appears to give off smoke or fog as it warms up and the carbon dioxide stops being a solid and returns to being a gas.

$\longrightarrow$Dry ice is special because as it transitions from a solid to a gas, it does not pass through a liquid phase. This process is known as sublimation.
