Explanation / Answer

1. Pouring water into a vacuum insulated container does not invole any phase change.

sublimation: solid to vapor

vaporization of alcohol: liquid to vapor

freezing water: liquid to solid

melting ice: solid to liquid

pouring water: liquid to liquid

2. The property of a solid is that the paricles have fixed position and are close together.

3. mass of keflex = 1.49g = 1490 mg

mass of keflex per each tablet = 250 mg/tablet

no. of tablets = total mass/ mass per tablet

no. of tablets = 1490 mg/ 250 mg/tablet = 5.96 tablets = 6 tablets.
