Can someonei can't get any in the science !

which of these experiments tests a chemical property of an object?

heating the object to determine its melting point

shining a bright light on the object and testing for decomposition

placing the object in water to see if it dissolves

trying to lift the object with a magnet

A chemical property would have to be something that changes and produces new substances. That is one of the main aspects of chemical changes/properties.

Heating an object to determine it's melting point is a physical property.

Shining a bright lighr and testing for decomposition however may be classifieds as a chemical properties because in the process of decomposition, organic substances are being broken. In physical properties, substances are not being broken.
