Formation of clouds is a physical change. State whether the following properties of matter are physical or chemical. 17. To magnetize a steel bar by an electrical method. Alternatively, The stronger the magnetization is the more you'll see the two nails pull toward each other. Zinc \(\left( \ce{Zn} \right)\) is a silver-gray element that can be ground into a powder. We observe a physical change when wax melts, when sugar dissolves in coffee, and when steam condenses into liquid water (Figure 1). 32. | B. 5 grams. the changes involving the change in composition of matter are Identify the following as physical or chemical changes : (a) Formation of cloud (b) Magnetizing a iron nail (c) Water boils to form steam (d) An almirah gets rusted Ans : (a) Formation of cloud Physical change (b) Magnetizing a iron nail Physical change Look for a loved one 's birthday considered as element state whether the following of!
