When alcohol dissolved in water why temperature of alcohol is increased?

The hydrogen bonds between water molecules and respectively hydrogen bonds between ethanol molecules are broken by mixing; new hydrogen bonds are formed between water and ethanol molecules - this second process is exothermic.

What effect does water temperature have on growing crystals?
If the temprature of water is increased the crystals would not be formed because they would be dissolved.
How does fresh water freezes faster than salt water?
When water has a substance dissolved in it, it freezes at a lower temperature. Salt water has salt dissolved in the water, so it freezes at a lower temperature than fresh water.
Why is temperature of boiling water cannot be measured using an alcohol thermometer?
Because the alcohol boils at a lower temperature than water.
When sodium hydroxide is dissolved in water the temperature of the water increases. Is this endothermic or exothermic?
Exothermic
What is the density of perfume?
The fragrance is usually dissolved in alcohol, and this in turn is dissolved in water. Otherwise, it would probably evaporate too quickly.
What effect does water temperature have on growing crystals?
If the temprature of water is increased the crystals would not be formed because they would be dissolved.
Does sea water boil at higher temperature than tap water and why?
Yes. Dissolved substances increased the boiling point.
What is a real life example of dissolved water?
A drop of water in a jar of pure alcohol would be water dissolved in alcohol.
Brine is to salt as punch is to?
Brine is salt dissolved in water; Punch is alcohol dissolved in water - therefore "Brine is to salt as punch is to alcohol." baking
What is the color when alcohol is dissolved in water?
It would depend on the colour of the alcohol and the quantity versus the quantity of the water.
how does temperature affect the concentration of dissolved oxygen?
Temperature has a direct effect on the concentration of dissolved oxygen in water. As the temperature of the water increases, the solubility of oxygen decreases and the concentration of dissolved oxygen will decrease. Conversely, as the temperature of the water decreases, the solubility of oxygen increases and the concentration of dissolved oxygen will increase. Additionally, warmer water is generally less dense than colder water, resulting in less efficient oxygen transfer.
How does fresh water freezes faster than salt water?
When water has a substance dissolved in it, it freezes at a lower temperature. Salt water has salt dissolved in the water, so it freezes at a lower temperature than fresh water.
Do alcohol at ordinary temperature has liquid or gaseous state?
Ethanol (the kind of alcohol you get in drinks) is liquid at room temperature. It boils at around 78'C, so will become a vapour at this point.
Brine is to salt as punch is to .?
Brine is salt dissolved in water; Punch is alcohol dissolved in water - therefore "Brine is to salt as punch is to alcohol."
State the relationship between water temperature and the maximum mass of ammonium chloride that can be dissolved in 100 grams of water?
As the temperature of the water increases, the amount of solute (in this case NH4Cl) that can be dissolved increases.
When water temperature increases what will the dissolved oxygen content do?
The amount of dissolved oxygen decreases when water temperature increases. Warm water is unable to dissolve as much oxygen gas.
Is dissolved oxygen increased by turbulence?
yes. if anything stirs up the water (turbulence) the oxygen content will be increased.
