Well, no.
The water is there to have a function too; it's a solvent that will take up the soap and facilitate its functioning. It'll also carry away all the dirt (including bits of virus) that it picks up in the process of washing.
That said, the chemistry won't care about whether you wash with cold water, warm water or boiling hot water, as long as you are using liquid water and are scrubbing properly for the required 20 seconds. So use whichever you find more comfortable. I know I don't want to feel like my fingers are freezing off my hands.
