Which statement describes a physical property of copper

A student performs the following experiment.

Step 1: She pours a colorless solution into a beaker that contains another colorless liquid. Yellow particles appear in the liquid.
Step 2: She lets the yellow particles settle in the beaker and then separates the colorless liquid by decantation.

What has most likely occurred in the beaker?

A. a chemical change in step 1 and a physical change in step 2
B. a physical change in step 1 and a chemical change in step 2
C. chemical changes in both step 1 and step 2
D. physical changes in both step 1 and step 2

The given question is which of the following describes a physical property of a copper metal. Now, the first option is given at high temperatures temperatures. A corporal forms a black corporal upside, it's actually corpora. Will we react with or will be combined with oxygen at high temperatures to cure corporate oxide, which is in black color, which is in black love. Okay, so you have two months and two months. So this is the balance do you want? So that faster statement is correct only and which is describes the property of copper matters. And the second property generally cooper slowly oxidizes slowly oxidizes to form to form green green color layer, green color layer. So it's like the statue on the liberty. Actually, the statue of Liberty is was made up what made up with copper metal. So therefore the copper Andrew goes corrosion in the presence of far oxygen and moisture. So therefore it undergoes oxidized oxidation and to form a See you see war three lord see you. Ohh twice compound. Okay, now, which is in green color which is in green color. So that the second statement is also a true statement which is described as the property of the cooper. And the third property is mentioned a copper is cooper metalist dactyls, cooper medalists a ductile. So this this statement also is a true statement. Actually, we are using electrical wires, which mostly made up with corporate method. So what is meant by a doctoral property. So the metal which can be drawn into a provides is said to be a doctor. I'll property. So this copper metal having a day activity. So therefore it can be Ah maybe they're 10 wives. So that the tax statement also correct statement. Now, the 4th statement is also a mansion. The 4th statement is corporal does not. Corporate does not react with that. Water does not react with water. So this is also described the copper metal property. Because corporate's let's react. Corporate is less react to. Then hydro's in corporate is less react to them hydrogen. This can be observing reactivity series. So therefore this couple does not react with the water too liberally hydrogen. Okay, so all the given statements are describes the copper metal properties. But the exact question is which is described as a physical property of copper. Okay, now, if you observe the first property, it is nothing matter a chemical property. It is a chemical property. Now a physical property. And the second property is also related to the chemical. It's not a physical because the composition of the corporate changes. Okay, so therefore it is also not a physical property. And third properties belongs to the physical property. Physical property because the copper metal composition is does not change is right. And the 4th property. 4th property is related to the chemical chemical reactivity. So the only character option is a third option, which describes the a physical property of copper metal

What are 5 physical properties of copper?
