What kind of state change did some of the water go through to make it disappear?
The water went through a phase change from liquid to gas, in a process known as evaporation. The heat energy from the surroundings caused the water molecules to gain enough kinetic energy to escape into the air as water vapor.
Is the formation of clouds a physical or chemical change why?
Clouding is a purely physical process of condensing vaporous water into liquid water (also freezing or sublimating it to solid ice / hail / snow) . Chemically nothing has changed (water molecules stay unchanged, still being water) only there (physical) state (this is a kind of 'condition' of matter) has changed.
What kind of changes are melting and boiling?
Melting is a phase change where solid becomes a liquid. The latent heat of fusion must be supplied to produce phase change from solid to liquid. About 144 Btu must be supplied to change 1.000 pound of ice at 32 degrees F to 1.000 pound of liquid water at 32 degrees F. Boiling is a phase change where a liquid becomes a vapor. The latent heat of vaporization must be supplied to change a boiling liquid to a vapor. For water boiling at 14.7 psia ,970.3 Btu of heat must be supplied to change 1.000 pound of boiling liquid water to vapor.
What kind of change happens to water when is boiled?
physical changeIn gas phase the molecules take more room, move fasterover (1000 times) longer distances before collating to other molecules as compaired to liquid.
When a log burned to ashes in the fireplace what kind of changes this?
The burning of a log in a fireplace is a chemical change, as the wood undergoes combustion to produce ash, smoke, and gases. The log is transformed into new substances with different properties, such as carbon dioxide and water vapor.
What kind of changes is it chemical or physical and why?
a physical change is a phase change, such as water to ice or water vapor. a chemical change takes place on a molecular level, producing a new substance.
When grape jello dissolves in hot water what kind of change happened?
chemical
What turns water vapor into water?
The wet kind
If you set a glass of ice water outside and melts what kind of change has happened?
A physical change. It can be reversed.
What kind of change goes from vapor to liquid?
Condensation.
Water moves from the surface of the earth into the atmosphere in what kind of water?
balanced
What kind of clouds are contrail?
Contrails are clouds that appear behind aircrafts. Contrails are long, thin, man-made clouds that are essentially vapor trails. These vapor trails are created by a change in water vapor or changes in air pressure.
What kind of gas is water vapor?
Water vapor is the gaseous form of water formed by evaporation of water. It is mainly derived as the gaseous form of H2O.
Is water vapor gaining or losing energy durning evaportaion?
Water vapor will have more energy than the water. Mainly, this is a kind of potential energy, related to the molecular attractions.
What kind of animal release water vapour?
Any animal with lungs releases water vapor.
What kind of liquid does water vapor turn into when it loses energy?
Water vapour turns into liquid water when it condenses
What kind of change is condesation?
Condensation is the change from gas to liquid.
