the particles of the hot water decreased by -20 which means that they where 480 calories transferred out of the hot water and the cold water increased 20 which means that they were 480 calories transferred into the cold water.
Temperature is a measure of molecular motion. Fast molecules are hot. Molecules that move slowly can always be "heated" and then they will move faster and thus will be hot.
hot water is made of molecules that can move faster and faster and you can boil or microwave the water to make it become hotter and hotter
because the hotter the water the quicker the particles move
Hot waterWhen substances have a high temperature, they have more energy. The more energy molecules have, the faster they move. The molecules in hot water move faster than cold water because of the higher energy. Because the molecules of hot water move faster, they can more easily break apart other molecules of a different substance when they come into contact. The fast moving water molecules can break apart the bonds between the salt crystals so they become dissolved into the water.
Hot water, because they have more energy.

Hot water molecules move a lot faster han cold water molecules because they have a higher kinetic energy due to the heat.

Cool water moves slow because the molecules are moving slow. In hot water, molecules are moving fast, thus, hot water seems to move faster than cold water at times.

Jelly dissolves faster in hot water because water molucules move faster at a higher temperature.
Jelly dissolves faster in hot water because water molucules move faster at a higher temperature.
Heat is the vibration of atoms, so atoms move faster. That's why you can clean things easier in hot water and why smells travel faster in a warmer room.
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.
