Question

01.05 HC) In science class, the teacher, Mr. Phillips, melts an ice cube as a demonstration. Jimmy states that he believes this is an example of a physical change. Which of the following best explains if Jimmy's claim is correct or incorrect? a This is correct because the ice has changed its composition. b This is correct because the ice only changed phases, not composition. c This is incorrect because the ice has changed its composition. d This is incorrect because the ice only changed phases, not composition.

Answer 1

This is incorrect because the ice has changed its composition.

A melting ice cube takes on a different shape as it begins to flow. Its makeup doesn't alter, though.

A physical change is an example of melting. A physical change is when a sample of matter undergoes a change that affects some of the material's attributes but not its identity.

The term "physical change" refers to the tearing, breaking, grinding, changing the state of matter, and dissolving of a substance. Exothermic reactions' opponent is known as an endothermic reaction. From their surroundings, they take in heat energy. This indicates that endothermic reactions make their surroundings colder as a result of the reaction. This sort of response can be seen in the melting of ice.
