Neither.
Tepid or room temperature water is generally considered the best for house plants.
The following URL will take you to an article from The New York Times published in 1878 where the author uses very hot water as an unusual plant remedy.

I'm not sure I'd try it on an expensive or much loved plant until I'd experimented a bit.
a plant will grow better in cold water because a plant is like a human being we refresh ourselves by drinking water usually cold water it is the exact same thing to a plant we give it water to grow
The plant would die
It will kill the plant's roots. Roots are in earth, which is usually a steady 55 degrees F. and hot water will damage the roots if it is too hot. The material that the plant is in also serves to keep the roots at a steady temperature. Water with a temperature no hotter than room temperature.
it depends on the weather!
tepid
yes
it will get hot
it will get wet...
Most waxes will soften if you put it into a bowl of hot water. If you put butter into the same bowl, it will also soften.
it will melt
The air in water bottle expands
it will swell, but won't lyse.
It would actually melt since the water is hot.
Because, the sun can only make plants grow when it needs water and when you put water on your plants they grow big, and big and that is from the sun because the sun is very hot.
It will pop just like water just not a bad
oxidation occurs and rust forms on the piece of iron from the oxygen in the water
it depends on the plant. some plants cant take a lot of water and other plants can absord a lot of water without it killing them
