When a solid material like 1) is heated, it absorbed heat. The heat absorbed/added to the material caused the material to change its form from 2)solidTo 3) . The material also changed its 4) , 5) , and 6) , when heated. When a solid material like 7) is cooled, it released heat. The heat released from the material caused the material to change its form from 8. to 9) . The material also changed its size, shape, and texture, when 10..

ok whats the question if not i cannot you i need question and need a thing to answer

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
