Ice cools down a drink because a. the ice is colder than the drink and heat flows into the ice cubes. b. heat is absorbed from the drink to melt the ice cubes. c. the heat of fusion of the ice is higher than the heat of fusion of the water. d. both a and b are correct.

Option (B) is the correct answer.

Explanation:

When we add ice in a drink then heat energy present in the drink will be absorbed by the ice. As a result, the ice tends to melt (change into liquid state).

Due to the melting of ice a cooling effect is observed because heat from the drink has been transferred to the ice. This melting of ice will continue until an equilibrium has reached, that is, temperature of both the liquids will become equal.

Thus, we can conclude that ice cools down a drink because heat is absorbed from the drink to melt the ice cubes.

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
