blown head gasket,often accompanied by cracked or warped cylinder head....usually caused by letting engine overheat previous to finding this situation. can also be caused by frozen water in engine without antifreeze (in below freezing weather,of course) cracking the engine block.
If you mix the two, you'll get water with a temperature somewhere in between. The exact temperature will dependon the temperature of the icy water and the boiling hot water; as well as on the exact amounts of water you mix.
Temperature increases
It's alright as long as the temperature of the air outside does not fall below freezing. Most cars have a 50/50 mix of antifreeze/water anyways. If the temperature does fall below freezing and all you have in the coolant system is water, it will cause a lot of damage to the engine and coolant system (it will freeze and expand, tearing hoses and could potentially damage internal components of your engine, such as the head gasket).
when cold and hot temperature mix together that cause rain
The temp sensor helps tell the engine how to mix the air and fuel to compensate for air temperature. If this isn't working then the air fuel mix can be off and cause rough idle.
The mixture is insoluble when the temperature is as low as cold water. In order to properly mix the temperature has to be raised, effectively increasing the solubility of the mixture.
The dye diffuses in the water.
Engine coolant is what I'm assuming you are talking about. Engine coolant is a mix of water and etholyn glycol (antifreeze). It pulls heat away from your engine block that builds up from the friction of moving parts. The coolant mix allows the coolant to get cold to a point and not freeze because of the etholyn glycol. It is also not good to put straight antifreeze into your engine because antifreeze does not have as much cooling potential as water antifreeze mix. Also if you have just antifreeze in your engine the antifreeze will boil at a much lower temperature than a mix of aproxamalty 50/50.
Blown head gasket
You get water at a temperature somewhere between the two.
It can allow water to mix with the engine oil and destroy the engine.
