When steel (or indeed anything) is heated its mass does not change. Volume is altered by cooling and heating. In this case the volume of the steel would increase.
no
No
No - it decreases
Only by an insignificant amount due to the mass-energy equivalence (from the Theory of Relativity). If you are interested in this, calculate the energy increment (in Joules) and divide it by the square of the speed of light (in meters/second). The resulting mass increment will be in kilograms.
The mass of TiO2 does not increase as it is heated. As TiO2 is heated, the titanium becomes more oxidised, and increases in oxidation state, and so oxygen is added to the molecule, making TiO3. As oxygen is added to TiO2, the mass you measure increases, but it does not stay as TiO2.
Any object will increase in mass, if you increase its energy (E = mc2). The effect is insignificant under normal circumstances.Apart from that, the mass of copper will not inrease. It will burn at some point and the reslulting compounds will weigh more.
The volume will increase, since most liquids tend to expand when they are heated. The mass will NOT increase, for most practical purposes - since there is something called "conservation of mass". However, the energy added to the liquid is equivalent to a small amount of mass; this is insignificant for most practical purposes.
Only an insignificant amount, due to mass-energy equivalence - the added energy implies some added mass.
Question makes no sense - unanswerable. Nothing changes mass when heated or cooled.
As the density of a substance increases the volume of a given mass of the substance decreases.
By the heating the colligion between atoms will increase so the mass of the air also increases.We cant measure the mass of air but we can measure it with the help of a container.
You look up the specific heat of copper (per mass unit). Then you multiply specific heat x mass x temperature difference.
