While conducting an experiment in a science laboratory, some grease unknowingly stuck in Sujan's shirt. After seeing it, he was worried. At that moment, his science teacher suggested to him to wash his shirt with little petrol instead of using soap and water for removing the grease. Does Sujan remove the grease from his shirt when he washes it with petrol? What is the scientific reason behind it

Respuesta :

Yes, Sujan is likely to remove the grease from his shirt when he washes it with petrol. The scientific reason behind this is that grease is a nonpolar substance, and petrol is also nonpolar. Nonpolar substances are attracted to each other, so the grease on the shirt will be dissolved in the petrol, allowing it to be washed away. Soap and water, on the other hand, are polar substances, which are less effective at dissolving grease. Therefore, using petrol is a more efficient method for removing grease stains from clothing. However, it's important to exercise caution when using petrol due to its flammable nature.
