Why does a drink get colder with ice?
The water has more heat than ice ... the water looses the heat to the ice the ice melts to become water .. but not warm water .. cold water that also looses heat to the warm water till equilibrium is reached and a final cool temperature is maintained .. but then the air around the water adds heat to the cold water till they all reach equilibrium and the water is warm again ..
How can a reversible reaction be reversed?
Reversible reactions are those where the products are in equilibrium at a set of conditions. For one of the most simple examples to illustrate this, look at ice water. At equilibrium conditions, a class of ice water is half ice and half water. If you shift the conditions by heating the ice water, ice will melt to bring the temperature back to equilibrium conditions but the ratio of ice to water will have changed.
What happens when we stir a crushed ice with water into the bottle?
the crushed of ice dissolve and become liquid, the equilibrium is stay at the bottle
What is the physical state of water at -24 degrees?
Solid.
Why Is ice water cooler than ice?
"Ice water" could either refer to water that has been chilled to the freezing temperature or just a container of water with ice floating in that is close to (but still above) that freezing temperature. Ice can be no warmer than the freezing point but can certainly be colder. If the solid (ice) is in equilibrium with the liquid ("ice water"), the ice will NOT be cooler, but as noted, if they are not really in equilibrium, you would expect the solid (ice) to be colder than the liquid water rather than the other way around.
Why is the puddle underneath the melting ice cube as cold as the ice cube itself?
The answer is that the system is in 'equilibrium'. More exactly thermal equilibrium. Ice and Water can both form at 0C and 1 ATM. When two things are touching, they are at equilibrium with each other. Since the ice cube has had enough time to melt, it has had enough time to reach equilibrium with the water and is at 0C.
Why is the puddle underneath a melting ice cube as cold as the ice cube itself?
The puddle underneath a melting ice cube is as cold as the ice cube because the water molecules that form the puddle still have low kinetic energy due to the loss of energy required for melting the ice. This means they remain at a low temperature, similar to the ice cube, until they absorb more energy from the surroundings to warm up.

Why will an ice cube melts faster in large amount of water than that of lesser amount?
The simple reason is that an equilibrium reaction is occurring. When the ice cube is immersed into water, there is a difference in temperature, and as a result of this an equilibrium naturally occurs, with the ice cube warming up and the surrounding water cooling down. The ice cube will melt faster in a large amount of water than in a lesser amount because there is more surrounding water, and there will be differences in temperature between the water immediately surrounding the ice cube and the water surrounding the water surrounding the ice cube, so the outer 'layer' of water is warmer than that of the 'inner layer' (surrounding the ice cube), and this in turn warms up the inner layer and the outer layer cools down, still trying to reach equilibrium. Due to this increase in temperature the 'inner layer' tries to reach equilibrium with the ice cube and 'outer layer' of water even quicker, to produce a consistent temperature throughout the water. In a lesser amount of water there is less water to cool down, so the ice cube won't melt as quick as less energy is required to cool the water, unlike in the larger volume of water
Does the water in a glass of icewater rise as the ice melts?
In physics terms, yes. Ice has a negative heat, which when added to water, the negative heat is then transferred into the water, cooling it off. Then the opposite becomes true as well. The heat of the water acts to melt the ice, then reach thermal equilibrium, which happens only when both the "ice" and the water are the same temperature.
What happens when we stir a crushed ice with water into the bottle?
the crushed of ice dissolve and become liquid, the equilibrium is stay at the bottle
Why does water flow into the bottom of a glass but ice doesnt?
Ice is less dense than water and therefore floats on water so when the glass has water in it the ice will always stay above the water.

Why does salt decrease ice's melting point?
Imagine water in contact with ice at equilibrium, at zero Celsius. Adding salt or any other water soluble substance shifts the equilibrium in favour of melting: Kinetic equilibrium between water and ice is maintained by constant interchange of water molecules between the solid and liquid phases. After adding a water soluble substance, there is a lower concentration of water molecules in the liquid, but the concentration of water molecules in the ice remains the same. Therefore, the equilibrium is shifted in favor of liquid (Le Chateliere's Principle), and the melting point must decrease to overcome this concentration change in the liquid. This freeezing point depression will be caused by any added solute and does depend on whether the heat of solution is positive, negative, or zero. (Melting point is an equilibrium property.)
If you place equal parts of ice and water in a glass what temperature will keep the ice from melting without causing the water to freeze as well?
Zero degrees is the freezing point and the melting point of water so this is the best you can get. But it would not be possible to keep your original lump of ice and not have any other water molecules joining it as ice or have any molecules leaving it as water. It will be in equilibrium, but equilibrium is dynamic - constantly changing at a molecular level whilst keeping its macroscopic properties (like how much ice overall) constant.
