When we heat metal its density decreases why?

1.	When we heat metal its density decreases why?
Answer» ong>Answer: When a metal is heated, its density decreases. There are two sources that give RISE to this decrease of ρ: (1) the thermal EXPANSION of the solid and (2) the formation of vacancies (SECTION 4.2). CONSIDER a specimen of gold at room temperature (20°C) that has a density of 19.320 g/cm3.
