There are three things you can do to dissolve the salt in water:
1) Stir the solution - you increase the rate at which water molecules will come in contact with the salt crystals
2) Grind the salt - the surface area of the salt will increase thus the contact area between ionic lattice of the crystal that can interact with water, is bigger
3) Increase the temperature - this will increase even more the rate of the solvation by increasing the kinetic energy of the particles
1) Recording the change in pressure when heating an inflated tire
Explanation:
This happens because with an increase in temperatures, the kinetic energy of the gas in the tire increases. The increase in kinetic energy means the molecules move more rapidly. There is an increased rate of collisions between the gas molecules, and increased energy of the collisions, and between the gas molecules and inner walls of the tire hence the increased pressure. Pressure and temperatures and directly proportional s long as the volume of the gas is kept constant.
