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

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
