I believe it is because it makes condensation and the object is under its freezing point.
a condensation of water will form on the outside of the metal container. What really happens is the frigid temperature of the cup actually cool the air down that it comes in contact with and water droplets form.
when ice and petrol are in same container ,ice will float on the surface of petrol, because ice is a frozen form of water .As water floats on oil it can not mix in it.
Ice is solid water. You can put them in drinks to keep them cold, use it for ice packs (if you get a bruise or to put in your lunchbox) etc. Ice is very cold and are usually in the form of cubes but can be made in any size, shape, or form. You can make ice by putting it in an ice tray or any container without a lid and putting it in the freezer until it becomes a solid. If you live in a place where the outside temperature drops below zero Celsius or 32 Fahrenheit, water left outside will turn to ice.
It is colder
The liquid to which you are referring is likely condensation - water. When water vapor in the air encounters something cold, such as a container with ice in it, the vapor tends to collect and condense into liquid water around the cold object. The same thing happens with a glass of ice water on a hot day.
It is different because, liquid water can (and will) take the form of the container it is in. We can also change the form of liquid water, unlike solid ice. Solid Ice wont take the form of the container it is in and we cant change its form without breaking it.
Ice cubes do not take the shape of their container because they are solid and maintain a fixed shape due to the rigid arrangement of their molecules. Unlike liquids, which can flow and conform to the shape of their container, solids have strong intermolecular forces that keep their structure intact. As a result, ice cubes retain their cubic form regardless of the container they are placed in.
Frost forms on the outside of a cold container when the temperature of the container's surface drops below the dew point of the surrounding air. This causes moisture in the air to condense into water vapor, which then freezes upon contact with the cold surface. The process occurs more readily in humid conditions, where there is a higher concentration of water vapor available for condensation. As the cold container cools the air directly around it, the resulting frost is a visible accumulation of ice crystals.
The lid of an ice container is a thermal insulator
The air around the beaker is cooled by the intense cold of the dry ice, causing water vapor in the air to condense and freeze on the surface of the beaker. This results in the formation of ice on the outside of the beaker.
The best ice cream container for storing homemade ice cream is airtight and freezer-safe container to prevent freezer burn and maintain freshness.
The outside of the cup is warmer drawing in condensation from the air and your drink.
