which of the following would increase in the rate of the salt dissolves

Question

cooling water
using salt cubes instead if crushed salt
stirring the solution

Answer 1

The rate at which salt dissolves can be increased by certain actions. Among the options you've provided:

1. Cooling water: This would generally slow down the rate of dissolving since warmer water usually dissolves salt faster.

2. Using salt cubes instead of crushed salt: This would likely slow down the dissolving process because larger particles have a smaller surface area compared to crushed salt, making it harder for the water to interact with the salt.

3. Stirring the solution: This would increase the rate at which salt dissolves as it helps to distribute the salt particles throughout the water and brings fresh water into contact with the salt, speeding up the dissolving process.

Therefore, stirring the solution is the action that would increase the rate at which salt dissolves.
