Someone please help! I just started chem and what’s an easy way to tell apart chemical and physical changes? For some reason I keep struggling with this :(

Chemical change is when the nature of something changes. Physical change is when a physical component changes.

Chemical change:

Example: Wood burns, it releases heat, produces CO2 and ash and you cannot reverse the burning.

Physical Change:

Example: Ice melts, water is formed, water can freeze again.

it's a simple answer :

Explanation:

Physical changes :

physical changes are those changes that can transform into a stage and have the ability to change himself to first stage .

Example: ice turns into water and water turns into a water vapour and again it becomes water and again becomes ice.

Chemical changes :

chemical changes are those changes which can transform into other products but cannot transform into his first stage .

Example: milk turns into curd but curd cannot turns into milk

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers
