Point out that when water freezes,the water molecules have slowed down enough that their attractions arrange them into fixed positions. Water molecules freeze in a hexagonal pattern and the molecules are further apart than they were in liquid water. Note: The molecules in ice would be vibrating....
There are certain cases that some compounds (classified as solutes) can be dissolved in a given solvent. One way to explain how a solute compound can be dissolved in a solvent (or how it is soluble to a solvent) is understanding what happens to the solute and the solvent molecules as it...
What kind of change occurs when salt dissolves in water? What can form as a result of a chemical reaction? What does a chemical reaction do? What happens to molecules in a chemical reaction? What is the difference between a chemical and physical reaction?
and the creation of bonds, or synthesis. Decomposition requires energy because the chemical bonds are initially stable, and energy is required to break them apart. The molecules in the bond have a lower energy level than free molecules; adding energy allows them to break free. ...
if you ever expose yourself to open space. Unfortunately, you can’t really prepare yourself for it or do anything to prevent it. After about 10 seconds of exposure, the water in your tissues will start to vaporize due to the absence of pressure holding the molecules of water close ...
Because no chemical reaction takes place when a mixture is formed, no energy (e.g. heat, light or electrical energy) is released or absorbed during the formation of a mixture.Do mixtures consist of atoms or molecules ?Mixtures can consist of either atoms or molecules - but must include at...
The state of matter can be changed by heating or cooling it or by changing the pressure conditions on it. When a material changes state, its molecules behave differently but don't break apart. Since they remain essentially the same, they don't form a different material but simply change the...
How Long Does It Take For Water to Freeze The scorching heat made people lose control, and even more when they did not get the cold water to drink. In hot weather, ice can be a challenge to acquire… What Happens If My Water Softener Runs Out Of Salt ...

What happens to water when it changes to ice? Phases of Water: Water exists in three phases on our planet, liquid water, ice, and water vapor. The differences in the phases of water according to the kinetic theory are the motion of the water molecules and how they behave. Differences in...
