Davon needed to open a glass jar of pickles, but the metal lid was on tightly . He ran hot water over the top of the jar, including the lid. Explain why the lid now opened easily.

Explanation:

By placing the jar under hot water, metal lid molecules expanded from heat which caused it loosen up. However, there can be a possibility where the jar lid was stuck because of the stickiness of the pickle juice which later got washed off or melted after placing the jar under hot water.
