A physical change; more water vapour has joined the cloud, making it thicker and less able to allow light through.
The formation of a cloud in the sky is a physical change. It occurs when water vapor condenses into tiny water droplets or ice crystals, which is a phase change rather than a chemical transformation.
Physical Change because a cloud is still a group of water molecules, they are just in a different phase.
It is a physical change.
yes
chemical
I guess it could be chemical, but really- it's a physical change
The chemical properties of a substance change during a chemical reaction, meaning the substance undergoes a chemical change and forms new substances with different properties. The physical properties may also change, such as color, texture, or state of matter.
This is a chemical change. When oxygen binds to hemoglobin, it forms a new compound with a different chemical composition. This process involves breaking and forming chemical bonds.
Yes, an ice cube melting into water is a physical change. In this process, the substance changes from a solid state to a liquid state without altering its chemical composition.
A physical reaction is when no new substances are formed, there is a change of state eg ice melting to a liquid. A chemical change is when the reaction forms a new substance. eg gas bubbles. An acid reaction can be both. You need to look at the reaction taking place, look for change of state (physical) or any colour change or gas bubbles (chemical).
when wood rots and forms humus is a physical change
Dissolving in water is a physical change.
It is chemical. It is chemical because when salt is formed from elements it becomes a chemical and not a physical.
Its is chemical as
Physical
Physical
It is always categorized as a Physical change as no new substance with different properties forms.
physical because doesn't matter if it forms its still a cave
I guess it could be chemical, but really- it's a physical change
It is a chemical change because the sodium(Na) is a liquid that forms with a yellow gas, chlorine(Cl), which changes the physical state to a dickmuncher solid, but ultimately they reacted with each other chemically to form salt (NaCl). It does change the physical state, but it is more of a chemical reaction.
Physical cuz after a while, mixed items separate back into two forms no matter what
its a chemical change which forms suphurous acid (H2SO3) and nitric acid (HNO3)
