Is bolling water a chemical change?
No, it's a physical change, for you can change steam back to its original state, water
Why is the water cycle a physical change?
because during a water cycle only the state of the water molecules are changed i.e. first from liquid to vapour and then to solid (snow and hailstorm) or liquid (rain). since there is a change only in the physical state of water and there is no change in the chemical properties of the water molecule it is a physical change.
When a cup of water at room temperature is put in a freezer the water's state of matter will change from?
This is an experiment. it will change from liquid to solid.
Water can change from one state to one state to another true or false?
True.
Is water evaporating into steam a physical change and why?
it is a physical change. It's obvious becuase it is just a change of state
Why doesnt temperature change when transferring from ice too water?
The thermal energy required to change state is taken from the environment; which in this case is the melt water.
Is decaying a chemical or physical changes?
Better to state it a biochemical change if required can state it chemical change
What is mean by reversible process?
It is a process that can change the state of something, which can if required be undone. Example, you can freeze water into ice, then reverse the process by allowing the ice to melt into water.
Is there loss of heat during change of state of matter from liquid to gas?
Yes there must be achange;but heat is required to change liquid state into gaseous state.
What type of energy is required to change ice to water?
Heat
What change of state form water vapor to clouds?
There are 3 changes of state.The change of state from water to water vapor is called evaporation.The change of state from water vapor to clouds is called CONDENSATION.The last state is precipitation,which is the clouds getting heavier resulting to the production of rain.
Is ice cream melting a change of state?
Transformatiom from liquid water to solid water (ice).
Is it lower in density ice or boiled water?
Assuming that it is not highly contaminated, water in it's liquid state will always be denser than water in a solid state. Being less dense, ice will float in water. As for boiling water, I'm not aware of any change in density of boiling water until it reaches it's required energy level to make the phase change to steam which is a gas and is no longer considered boiling water.
What is specific latent heat.?
It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.
Is water being split to form two new substances hydrogen and oxygen a change of state?
No. It is a chemical change. Simply boiling water would be a change of state.
Is bolling water a chemical change?
No, it's a physical change, for you can change steam back to its original state, water
When a substance from any state of matter to another is called a?
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
