When a solution is heated and then cooled, the solubility of the solute generally increases as the temperature rises, allowing more solute to dissolve. Upon cooling, the solubility decreases, causing the excess solute to precipitate out of the solution in the form of crystals.
Oil does expand when heated and contracts when cooled.
As the saturated solution is cooled slowly, the solubility of the solute decreases due to the decrease in temperature. This causes the excess solute to start crystallizing out of the solution in the form of solid crystals. The crystals will continue to grow as more solute particles come out of solution until equilibrium is reached.
When a substance is heated, the molecules gain kinetic energy and move faster, causing them to vibrate and collide more frequently, which increases the temperature of the substance. When a substance is cooled, the molecules lose kinetic energy and move slower, reducing the frequency of collisions and vibrations, which lowers the temperature of the substance.
Bromthymol Blue, when heated in a solution, indicates carbon dioxide. If there is carbon dioxide in the solution, it will turn bright yellow (when heated).
Supersatured.
it will not attract
they tend to vibrate
When heated it get larger and when you freeze it the matter gets smaller with an exeption to ice
The flesh will bring out goose pemples
what changes take place when water is heated or cooled
ammonia should release on heating.
what changes take place when water is heated or cooled
The opposite of heated is cooled.
When materials are heated, the particles gain kinetic energy and move faster, leading to expansion of the material. Conversely, when materials are cooled, the particles lose kinetic energy and move slower, causing the material to contract or condense.
A solid can change Into a liquid when it is heated Example- when heated solid chocolate, the chocolate changes into a liquid. A liquid Can change into a solid when it is cooled Example - If you leave juice in the freezer , the liquid changes into a solid.
Cooled to set
