i dont know about energy,but the speed of water increases as the density of water increases with rising temperature..

Does it take less energy to heat hotter water than colder water?
Yes, as the molecules of the hot water are already in motion, they need less energy to speed up and transfer it whereas the molecules of cold water need far more energy so that they get into motion and then transfer energy.
What is it called when particles speed up?
Heat is thought of as the random kinetic energy of a substance. So if a cup of water gets hotter, the molecules in the water speed up. Heat can cause particles in a substance to move around, to vibrate, or to spin.
How do you explain the increase in pressure in a closed system when temperature is increased?
Since the temperature is increased, the molecules start moving to and fro... which tends increase in speed of the molecule.. such that the increase in temperature is directly proportional to the speed of the molecules by which the pressure will also increase...
What is the speed of an object increases its kinetic energy .?
The kinetic energy depends on both mass and speed. If either mass or speed increase, the kinetic energy will increase as well.
Why do Atoms and molecules have kinetic Energy?
Because they: * Have mass * Have a speed
When a substance cools kinetic energy causing the speed of the molecules to?
decreases; increase
What does a temperature increase cause the rate of a reaction to increase?
As temperature increase the speed and energy of molecules increase and the collisions are more probable.
What a does a temperature increase cause the rate of a reaction to increase?
As temperature increase the speed and energy of molecules increase and the collisions are more probable.
If you increase the temperature of a gas what happens to the movement of the molecules?
Their average kinetic energy, and hence their speed, increases.
Why do materials get a little larger when they get hotter?
when materials get hot their molecules get energy,speed up and exert greater force on the edges due to which materials expand.
What makes an object have more kinetic energy?
An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly. An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly.
How fast does diffusion take?
Faster diffusion will take place if the surroundings are warmer. Increase in temperature means an increase in molecules' speed (kinetic energy).
Does it take less energy to heat hotter water than colder water?
Yes, as the molecules of the hot water are already in motion, they need less energy to speed up and transfer it whereas the molecules of cold water need far more energy so that they get into motion and then transfer energy.
What happens in diffusion if the temperature is raised?
At higher temperatures, atoms and molecules have more kinetic energy, and they will diffuse more easily. Diffusion rates are proportional to temperature. The hotter it is, the higher the diffusion rates we will see.
What effect does an increase in temperature have on the movement of molecules?
Molecules create friction from rubbing together causing the temperature to increase.
What happens if water molecules are speedes up?
If they speed up fast enough, they turn to steam (water vapor).
What is the relationship between speed and kinetic energy?
The kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.
