At room temperature you get an addition reaction, while at high temperature you get a substitution reaction.

Explanation:

At room temperature

You get an electrophilic addition reaction.

"H"_2"C=CHCH"_3 + "Cl"_2 stackrelcolor(blue)("room temperature"color(white)(mm))(→) "ClCH"_2"-CHClCH"_3H2C=CHCH3+Cl2room temperaturemm−−−−−−−−−−−ClCH2-CHClCH3

At high temperature

You get a free radical substitution reaction.

"H"_2"C=CHCH"_3 + "Cl"_2 stackrelcolor(blue)("high temperature"color(white)(mm))(→) "H"_2"C=CHCH"_2"Cl" + "HCl"H2C=CHCH3+Cl2high temperaturemm−−−−−−−−−−−H2C=CHCH2Cl+HCl
