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, an empty container will not increase in mass when heated. Heating an empty container will not create additional matter within the container to increase its mass.
no
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.
Only an insignificant amount, due to mass-energy equivalence - the added energy implies some added mass.
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.
When copper is heated, its temperature increases which causes its atoms to vibrate with higher energy, leading to a slight increase in mass due to the higher kinetic energy of the particles. This increase in mass is so minimal that it is usually not observable in most situations.
As the density of a substance increases the volume of a given mass of the substance decreases.
When matter is heated, the particles within the matter begin to vibrate faster and move farther apart. This leads to an increase in volume without a proportional increase in mass, resulting in a decrease in density.
No, the mass of sodium hydrogencarbonate (baking soda) remains constant when it is heated. Heating baking soda causes it to undergo a chemical reaction where it decomposes to form water, carbon dioxide, and sodium carbonate.
When an object is heated, its atoms vibrate faster and take up more space. This leads to a decrease in density, as the mass stays the same but the volume increases.
