Food colouring dissolves faster in hot water because the water molecules have more energy and they move around more creating larger gaps for the food colouring molecules to fit into, while the cold water has less energy and the water molecules are closser together making it harder for the food colouring to dissolve
Sugar dissolves faster in hot water, because the water molecules move about faster when they are hot so, when you pour in sugar, the water mollecules will collide with the sugar and theredore sugar dissolves faster in hot water.
Hot water mixes with food coloring faster than cold water. The heat increases the speed of molecular movement, allowing the food coloring to disperse quicker and more thoroughly.
The hypothesis would be that food coloring will spread faster in hot water compared to cold water due to higher temperature increasing molecular movement and diffusion rates.
Crushed salt dissolves faster in cold water compared to rock salt. This is because crushed salt has a larger surface area for water molecules to come in contact with, facilitating faster dissolution. Rock salt, on the other hand, has a smaller surface area which slows down the dissolution process.
Jelly usually dissolves better in hot water because the heat helps to break down the gelatin and sugar molecules more effectively. Hot water also speeds up the dissolution process compared to cold water.
Powdered juice dissolves faster in hot water, but tastes better in cold water.

Sugar.
Somewhat, but it dissolves faster in warm water.
yes
Probably hot water.
Sugar dissolves faster in hot water, because the water molecules move about faster when they are hot so, when you pour in sugar, the water mollecules will collide with the sugar and theredore sugar dissolves faster in hot water.

Warm Water! when molecules inside of an object heat up, the molecules go faster! which will absorbe the food coloring faster.
I just did an experiment on this actually. Water molecules travel faster in hot water than in cold water. When food dye is added into hot water where the molecules are traveling faster, it mixes faster. In cold water, the particles are not traveling as fast and the food dye does not spread as fast.
