Precipitation has to be an exothermic process. We know this because the overall entropy change having to be positive (second law of thermodynamics) - and because the entropy change of the system is negative (two liquids forming one solid and one liquid) the entropy change of the surroundings must be positive (and also large enough to make up for the decrease in entropy of the system) for the overall entropy to be positive and the reaction to be spontaneous. Positive entropy of the surroundings equates to a negative value for delta H (and therefore an exothermic process).

What snow and rain have in common?
Snow and rain are both forms of precipitation that occur in the atmosphere when water droplets or ice crystals coalesce and fall to the ground. They are essential components of the Earth's water cycle, playing a crucial role in replenishing freshwater sources and sustaining ecosystems. Both snow and rain are influenced by factors such as temperature, humidity, and atmospheric conditions.
What is three types of precipitation?
The 4 main precipitaions are rain, hail, sleek and snow
What word means both rain and snow?
Precipitation means snow, sleet or rain.
Which is an example of preciptation?
In regards to weather, precipitation is rain,snow,sleet etc
Did it rain or snow in paleozoic era?
yes it does rain
What is the converse of if the rain is frozen then turns into snow?
Snow melts turning to water.
Is reaction of potassium iodide and water exothermic or endothermic?
Its endothermic... In my experiment, it went from 26 to 25 degrees celsius... Its endothermic... In my experiment, it went from 26 to 25 degrees celsius... This is wrong it is exothermic. Potassium chloride is snow salt. it is used because not only does it react with the snow to create hydrochloric acide and potassium hydroxide (both with much lower freezing points) but, the EXOTHERMIC reaction also helps melt the snow No, it is endothermic. The only reason we add salt to snow is to lower the melting point. If you're curious, dissolve as much KCl in a beaker as you can as quickly as you can. The water temperature will drop dramatically.
Is rain turning to snow a chemical reaction?
No, rain turning to snow is a physical process, not a chemical reaction. It occurs when raindrops freeze as they fall through a layer of cold air near the Earth's surface, forming snowflakes.

What is the relationship between weather and water?
The water cycle is driven by energy from the sun. Liquid water is evaporated and changed into a gas. In this process, energy is absorbed (endothermic). The gaseous vapour rises and circulates in the atmosphere, cools and changes back into a liquid. This process is called condensation and releases energy (exothermic). Tiny droplets of water in the atmosphere accumulate to form clouds, which can return the water to Earth as precipitation, namely rain or snow.
What is three types of precipitation?
The 4 main precipitaions are rain, hail, sleek and snow
Is snow rain?
No, snow and rain are two different forms of precipitation. Snow falls as frozen ice crystals, while rain falls as liquid water droplets. Snow forms when the temperature is cold enough for water vapor to freeze before it reaches the ground, whereas rain forms when water droplets combine and fall from clouds.
What are the four major types of precipitation?
The four major types of precipitation are rain, snow, sleet, and hail. Rain is liquid water droplets falling to the ground, snow is ice crystals falling to the ground, sleet is rain that freezes as it falls, and hail is ice pellets formed in strong thunderstorms.
What are two forms of precipitation?
* Rain * Snow * Sleet * Hail * Freezing Rain
What is the other name of rain or snow?
SNOW OR ICE
What are 4 examples for precipitation?
