Methonal does not exist.
Methanol (CH3OH) or methanal (CH2O) do exist, which one do you mean.

Is the freezing point of ice cream lower or higher than the freezing point of water?
It is lower.
Why is the temperature needed to freeze the ocean water lower than the temperature needed to freeze the surface of a freshwater lake?
Dissolved salts in water contribute to a decrease of the freezing point.
Why is the temperature needed to freeze ocean water lower than the temperature needed to freeze a surface of a fresh water lake?
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.
Why does pond water freeze easier than salt water?
Saltwater has a much lower freezing point (the freezing point is the temperature where something freezes) than fresh water does. The more salt there is in water, the lower is the freezing point.
Why does saltwater take longer to freeze?
The freezing point of a solution is lower than the freezing point of the solvent; for this phenomenon a theory exist and an also a formula to calculate the decrease of the freezing point. See the link below.
What temp is needed to have rain?
higher than freezing, lower than boiling
What conditions are needed for liquid water?
Temperature higher than freezing and lower than boiling.
Is salt water colder than fresh water?
The freezing point of salted water is lower than the freezing point of pure water; this is a phenomenon known as freezing point depression when a solute exist in the solution.
Why is the freezing point for ocean water lower than fresh water?
Because ocean water contains 3.5 % salt.
Why sea water freezes at a lower temperature than fresh water?
The salt present in sea water lowers its freezing point.
Why does sea water freezes at a lower temperature than fresh water?
The salt present in sea water lowers its freezing point.
The accumulated salts in seawater make the seawater much more dense than fresh water One of the characteristics of salt water is that it has?
A lower freezing point than fresh water
Why does sea water freezes faster than fresh water?
sea water doesnt freeze faster than fresh water, fresh water freezes faster than sea water as it has a lower freezing point than sea water has as sea water contains salt which makes the boiling/freezing points increase therefore making the sea water freeze at a lower temperature.
How many grams of ethylene glycol automobile antifreeze C2H6O2 dissolved in 3.80kg of water is needed to lower the freezing point of water in an automobile radiator to 21.0C?
None. The freezing point of pure water is already lower than that.
What are the constants between salt water and fresh water in regards to freezing?
The difference is that fresh water will freeze at 0.c and salt will freeze to a lower temperature due to the presence of impurities (salt).
Why in polar regions some of the water is frozen to snow while sea is left unfrozen?
The sea is salt water which has a lower freezing point than fresh water in the snow. Additionally the sea is continually moving (waves) which will need a lower temperature to cause freezing
Is the freezing point of ice cream lower or higher than the freezing point of water?
It is lower.
