Why is a mirror cleaned with an alcohol solution is slightly colder right after it is cleaned?
Cleaning a mirror with an alcohol solution causes the alcohol to evaporate quickly, absorbing heat from the mirror's surface and the surrounding air. This rapid evaporation process leads to a decrease in temperature, making the mirror feel slightly colder immediately after being cleaned.
What else can I help you with?
Why does alcohol temp is low?
Actually alcohol at room temperature would be of the same temperature than water at room temperature. The difference between the two is that alcohol needs less heat to evaporate. If you wet either hand in alcohol and water, the one with alcohol will feel colder because it's removing more heat from you and faster. That's basically what cold is, the absence of heat.
Will epsom salt make water colder?
Yes Epsom salt will make water colder because it uses the water's natural heat energy to split apart ionic bonds of magnesium and sulfate. At this point the solution would be considered endothermic because more heat energy is being used than is being produced. This is why Epsom salts are used to soak a sprained ankle and to draw heat out of an injury.
Why does water get cold when you mix potassium nitrate?
When potassium nitrate dissolves in water, it absorbs heat from its surroundings to break the bonds between the ions, causing the solution to become colder. This process is called an endothermic reaction, which means it requires energy input to occur. This is why mixing potassium nitrate with water results in a cold sensation.
A solution that contains all the solute it can hold at a given temperature?
It is called a saturated solution. This is created by adding in solute until no more solute dissolves. Then the excess solute is filtered. This works much better for a saturated solution at room temperature, as when the solution hits the filter paper, some will come out because it is colder.
What colligative property is responsible for antifreeze?
The colligative property responsible for antifreeze is freezing point depression. Adding antifreeze (such as ethylene glycol) to water lowers the freezing point of the solution, preventing the liquid from freezing at lower temperatures.
Is it colder at top or bottom of a refrigerator?
It is colder at the top of a refrigerator because cold air sinks, causing the lower portion to be slightly warmer.
Which is colder - Vancouver or Montreal?
Montreal has colder winters Vancouver has colder summers
Why is rubbing alcohol colder than water when you blow on it?
The evaporation is quicker than water
Is 27degrees faranhit cold?
32 degrees is the freezing point. So 27 is slightly colder than that.
What is the weather like in 1500s?
The same as it is now, although studies have shown it was slightly colder further back in history.
Is 35 degress Fahrenheit or 35 degrees celsius colder?
35° Fahrenheit = 1.7° Celsius 35° C = 95° F 35° F is only slightly warmer than ice. 35° C is only slightly cooler than body-temperature. 35° F is colder.
What is thermal reactions?
An Exothermal reaction is a chemical reaction that produces heat making the solution warm or hot. It is the opposite of an Endothemic reaction which makes the solution colder.
What occurs when 10 grams of water is changed from 15.5 to 14.5?
Assuming that refers to the temperature: the water gets slightly colder.
What is ex thermal reaction?
An Exothermal reaction is a chemical reaction that produces heat making the solution warm or hot. It is the opposite of an Endothemic reaction which makes the solution colder.
Does shaking a milk carton makes the milk colder?
No. Actually, the friction that you are creating inside the carton is likely to make the milk warmer. The best way to make your milk colder is to put it in the refrigerator. -- No - if anything, the agitation of the molecules will increase their temperature slightly. It may feel that it get colder as the milk moves about and the parts of the container you are touching might have colder milk move under it.
Which is colder ice cold or rice cold?
Ice cold is colder than rice cold. Ice is typically at or below freezing temperatures, while rice is usually stored at room temperature or slightly cooler.
Why do objects feel cold when your hand has been in hot water?
Because as your hands are warm and the object is slightly colder then it makes a big difference...
