Questions
1. Why do people who own washing machines still go to the dry cleaners?
2. Can you suggest two advantages of recycling the solvents used in the dry-cleaning process?
3. Heat generally causes materials to expand. If this is true, why do some fabrics shrink when washed?
1. People who own washing machines still go to the dry cleaners because some clothing is made from materials that can be shrunk or damaged in water. Also, some stains can not come out with water so the dry cleaners could fix hard stains as well.
ReplyDelete2. First, the recycling could help the environment so there is less waste. Second, it would save money because the dry cleaners would not have to go buy more chemicals or pay for more water.
3. Some fabrics when get wet make the molecules move very slowly. This causes the clothes to shrink since the molecules are not making the fabric expand.
1. Because some clothes can't be washed with water or they would be ruined.
ReplyDelete2. By recycling the solvents used in this process, it is less wasteful the amount of the material used can be minimized.
3.Some shrink when washed because due to the lessen of heat energy, the water molecules move slower and become closer together, which contracts the fabric in some clothing.
1. People still go to the dry cleaners because some clothes can be harmed by water and some stains are insoluble in water.
ReplyDelete2.Recycling the solvents used in dry cleaning could save the cleaners money and help the environment.
3. Some fabrics shrink when washed because when the fabrics are put in the dryer and are heated the fibers cannot stand the heat.
People who own washing machines still go to the dry cleaners because some clothes require dry cleaning because they will shrink with water. By recycling they don't waste harmful materials and release them into the environment. The materials still shrink because there is water, which is why you go the dry cleaners who don't use water.
