remain constant as no mass is lost or gained during a physical change like heating copper.
the copper must have combined with another substance.
When copper oxide is heated, it undergoes a chemical reaction that causes it to lose oxygen atoms, resulting in the formation of copper metal. The mass of the copper metal formed is equal to the mass of the original copper oxide. Therefore, the overall mass remains the same.
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.
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.
When hydrated copper sulfate is heated, it loses water molecules and forms anhydrous copper sulfate, which has a lower mass due to the removal of water. So, the mass would decrease upon heating hydrated copper sulfate.

When copper is heated it oxidizes. The additional oxygen molecules it takes on when oxidizes leads it to have a higher mass.
Solid copper appears to gain mass when heated in air, because the copper reacts with oxygen in the air to form copper oxide. However, the actual mass of the copper does not increase; the mass of the solid increases by a value equal to the mass of oxygen removed from the air.
Only an insignificant amount, due to mass-energy equivalence - the added energy implies some added mass.

it went up because the mass increases

The copper wire glows red. Once it cools...the copper reacts with the air to produce copper(II) oxide. This is shown by the black tarnish on the copper wire.
To determine the mass of carbon on the weighing dish, you would need to know the total mass of the dish plus the carbon. If, for example, the combined mass of the dish and carbon is 5.0 g, then the mass of the carbon alone would be 5.0 g - 1.0 g (mass of the dish) = 4.0 g. Without the total mass, the mass of carbon cannot be calculated.
