Hello, I  need help with the part I outlined!

Changes of matter are chemical - change the nature of c.p's (> appearance also) - if they look similar only for some substances. (60 yrs, acid rain) sculpting is P weather causes: pitting specific to marble (CaCO3) > is C marble! weather causes: machining is P iron (Fe) rusting specific → is C to iron! Air is disinfected with UV Ilight: P Stalagmites grow: Cooking pan is preheated: P Jeans are worn out to holes: Bamboo grows: Cooking pan is degreased with soap: Jeans are bleached to white: Air is humidified: » Chemical changes + reactions often make/change: color, odor, taste, light, gas, heat, precipitate.. C/P?
