Answers
Answer:
- What is aerosol made of?
Ans :- Although 'aerosol' refers to a finished product, it is made up of four components: the container, the valve, the actuator and the cap. The container can be made from different materials but is usually made of tinplated steel or aluminium. It provides optimal conditions to store the product to be sprayed.
2. What is the dispersing medium of a smoke?
Ans :- The dispersion medium is gas and the dispersed phase is solid. It is an aerosol. Aerosol contains small particles of liquid or solid dispersed in a gas.
3. What phenomenon is created when the dispersed colloid particles scatter light?
Ans :- the Tyndall effect
The dispersed particles of a colloid cannot be separated by filtration, but they scatter light, a phenomenon called the Tyndall effect .
4.What are the two components present in the colloid?
Ans :- The two components of a colloidal solution are dispersed phase and dispersing medium.
5.How can we categorize colloids?
Ans :- A common method of classifying colloids is based on the phase of the dispersed substance and what phase it is dispersed in. The types of colloids includes sol, emulsion, foam, and aerosol. Sol is a colloidal suspension with solid particles in a liquid. Emulsion is between two liquids.
6. In what category of colloids does marshmallow belongs?
Ans :- Well, marshmallows are a special type of colloidal dispersion called a foam. A foam is air suspended in a solid. In this case, the gelatin protein expands to trap air within the liquid matrix and create a solid gel.
7.What does sol mean?
Ans :- Sol is a colloidal suspension with solid particles in a liquid. it is in module. A sol is a type of colloid in which solid particles are suspended in a liquid
8.Is dust a colloid? If so, to what category does it belongs?
Ans :- Dust is a colloid if suspended in air. It consists of a solid in a gas, so it is a aerosol. Whipped cream is a colloid.
9.What is the dispersing medium of a mayonnaise?
Ans :- the major component in mayonnaise (oil) is forced to be fine droplets to disperse throughout the lesser amount of continuous aqueous phase (dispersed medium). Mayonnaise is known as an oil-in-water (o/w) emulsion.
10.What is a colloid?
Ans :- colloid, any substance consisting of particles substantially larger than atoms or ordinary molecules but too small to be visible to the unaided eye; more broadly, any substance, including thin films and fibres, having at least one dimension in this general size range, which encompasses about 10−7 to 10−3 cm.
