Plz help me frnds​

Answer 1

1. dry ice: solid carbon dioxide obtained by cooling and applying pressure on carbon dioxide gas. ... Dry ice is made from carbon dioxide gas. The carbon dioxide gas is pressurized and cooled to formliquid CO2. The liquid carbon dioxide is injected into either a block press or pelletizer.

1. Factors that affect evaporation include the concentration of the evaporating substances in air, temperature, air pressure, the rate of airflow and surface area.
2. Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.

Mark me as a brilliant answer

Answer 2

1.)Dry ice is solid form of co2 or carbon dioxide

2.) Factors affecting evaporation are

HUMIDITY

SURFACE AREA

WIND SPEED

AIR PRESSURE

TEMPERATURE

3.) SOLIDS HAVE HIGH MELTING AND BOILING POINT

LIQUIDS HAVE COMPARATIVELY LESS MELTING POINT AND BOILING POINT

GASES ARE THE LEAST

4.)COTTON IS MORE COMFORTABLE BECAUSE IN SUMMER SWEAT COMES AND DUE TO SMALL PORES IN COTTON SHIRT IT WILL EVAPORATE WHEREAS IN NYLON IT WON'T
