What happens if you add or remove energy to a glass of water?
if you add it will stay liquid but if you remove it will freeze
Can the state of matter change when you add or take away energy?
Yes, particularly if you add thermal energy. At its least energetic, matter is in the solid state. Add some more energy, it transitions to the liquid state. Then more and it's a gas. Finally, at its most energetic, it is in the plasma state.
Energy need to change a material from liquid to gas?
You can add heat and cause liquid to gasify. Or you can decrease the pressure in the system and cause liquid to gasify. Note that you may gasify liquid and leave suspended or dissolved solids behind. More heat or pressure may be required to convert these remnants to liquid and then gas.
What force has to be overcome in order to change a solid into a liquid?
you have to add or take away energy
Do you have to remove energy form liquid to make it a solid?
The process of freezing, by which a liquid changes to a solid, technically doesn't require energy. In practice, if you have to make icecubes in your freezer, you do use energy - but the energy content of the ice is still lower than that of the water. Freezing happens by losing energy, not by gaining it. Whereas melting a solid into a liquid does require energy.

How is heats energy involed in changing the phase of water?
For example, to melt ice, you need to add heat energy. To freeze liquid water (to turn it back into ice), you have to remove heat energy.
Does solid liquid have less or more thermal energy?
It has less because you add a solid and liquid together and you get less.
When you add energy to a liquid .?
It becomes a gas
Can the state of matter change when you add or take away energy?
Yes, particularly if you add thermal energy. At its least energetic, matter is in the solid state. Add some more energy, it transitions to the liquid state. Then more and it's a gas. Finally, at its most energetic, it is in the plasma state.
Would you add heat or take away heat to freeze a liquid?
Freezing is an exothermic process.
How can water exist as both a solid and a liquid at degrees Celsius?
Ice does not melt all at once, and water does not freeze all at once. If you add heat energy to ice, it will melt at 0 oC. If you take away heat energy, water will freeze at 0 oC. The temperature will not change until the phase change is complete, so during the phase change, both liquid water and ice will be present.
How can you preseve a liquid drink?
freeze it, refrigerator it, evaporate it then when wanted to drink add water, put in a sealed container
What happens if we add thermal energy to a liquid?
It will get hotter. Eventually it may evaporate.
Can a solid change into a gas without changing into a liquid?
Yes. It can go directly into a gas when you add more energy!! This process is known as sublimation.

How do the changes of state relate?
Energy. When something is in a solid state its atoms are not moving and their electric charge keeps them close together. As you add energy usually heat they begin to vibrate and thus the attraction lessens. This results in a liquid. Add even more energy and you get a gas.
