gas.
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.
No, the conversion of liquid water into gaseous water is a physical change, not a chemical change. This process, known as evaporation, involves only a change in the physical state of the water molecule, not its chemical composition.
Water vapor is in the gaseous state.
The transformation of a physical state of a substance into a different physical state is called a phase change. An example of this is water changing from solid (ice), to a liquid (water), to a gas (steam).
The evaporation of water in a lake is a physical change. This is because the water is changing state from liquid to gas without any change in its chemical composition.
130c is very hot (water boils at 100c)
No it is the temperature at which water changes physical state from a liquid to a solid.
the physical state is having problems.
Ice is water in a solid state.
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
Being liquid is a physical property. Being water (H2O) is a chemical property.
Solid.
Water exists in all physical states. Water exist as vapors, snow and droplets.
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.
At this temperature water is a solid.
No, the conversion of liquid water into gaseous water is a physical change, not a chemical change. This process, known as evaporation, involves only a change in the physical state of the water molecule, not its chemical composition.
Freezing of water is a physical change because it involves a change in state from liquid to solid without altering the chemical composition of water. The molecules in water rearrange to form a crystalline structure in the solid state but remain as H2O molecules.
