Answer 1

1.The molecules of carbon dioxide when cooled loose their kinetic energy very quickly and therefore become directly into solid. The solid carbon dioxide (dry ice) is stored under high pressure so that it does not convert into gas. 2. The vapour pressure is the measure of how fast a liquid changes into vapour. As we know acetone becomes vapour much faster than water it has a high vapour pressure. This can also be thought in a different way, vapour pressure is inversely proportional to boiling point. S
