How long does it take a ice cube to melt in a cup of room temperature salt water

Explanation:

A 1 inch ice cube, submerged in a cup of cold water would take about 15-20 minutes to melt. In a room temperature water, it would melt in 5-10 minutes

The difference between the air temperature and the freezing point of salt water is bigger than the difference between the air temperature and the freezing point of freshwater. This makes the ice with salt on it melt faster. Try putting ice in a glass of cold water. Leave it there for 10 minutes or so.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
