chemical change
No, the weight of an object does not change when it changes states of matter because weight is determined by the gravitational force acting on the object, which remains constant regardless of its state of matter.
Yes, matter can change states after a physical change. Physical changes involve changes in the arrangement of particles without altering the chemical composition. For example, melting ice (solid to liquid) and boiling water (liquid to gas) are physical changes that involve changes in state.
There are different processes involved during changes in states of matter. The most common ones include melting, evaporation, condensation and freezing.
True
well both states of matter are changed/ has changed
A solid is a state of matter that does not change in volume because the particles are closely packed together and have fixed positions.
I really dont know lol
A person who studies changes in matter is called a chemist. Chemists investigate how matter changes at the molecular level, including processes like chemical reactions and phase changes. They use principles of chemistry to understand, analyze, and manipulate matter.
When thermal energy is added or removed, the state of matter changes to another eg. solid becomes liquid and liquid becomes gas.
"The" two changes are wrong. There are lots of different states of matter, and therefore many different possible transitions. The most commonly studied states of matter are solid, liquid, and gas; each of them can change directly to each of the others, for a total of 6 types of change.
true
The different changes in matter,basically,are phsical change and chemical change. You must understand that matter can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ). Changing physical states is not a chemical change, but a direct result of heat or cold application.
