Maya poured very hot water into a thick glass jug, and it cracked. Her brother told her that if she had put a stainless steel spoon in the glass and then poured the hot water the glass would not have cracked. Could this be possible? Give a reason to justify your answer
Answers
Answer: The glass jar wouldn't crack if a stainless steel spoon was put inside in while there was hot water in it.
Explanation: Glass is a poor conductor of heat(i.e, it is an insulator of heat). When hot water is poured into a glass jug, the hot water comes in contact with the surface of the jar, as the glass doesn't absorb the heat, the space between the molecules to expand due to the heat as because the molecules of a substance move a lot faster at high temperature causing the glass jar to break. On the other hand, steel is a good conductor of heat. If we put a stainless steel spoon in the glass jar filled with hot water, the spoon being a good conductor of heat absorbs a lot of heat and thus the glass jar doesn't crack or break.
