The atoms in the mass become more energetic and create more pressure. If the bounds of the container allows it, such as in a balloon, the gas will expand. If the bounds doe not allow it, such as in a fixed container, the pressure will increase.
When magnesium is heated in air, it reacts with oxygen to form magnesium oxide. The total mass of the system, which includes the magnesium and the oxygen it reacts with, remains the same according to the Law of Conservation of Mass.
When a substance is heated, its mass remains constant because mass is a measure of the amount of matter present, which does not change during a physical change like heating. Volume may expand due to thermal expansion, where the particles move farther apart. Weight may appear to change due to differences in gravitational force, but the actual mass remains the same.
As a hydrated compound is heated, the water molecules contained within it will evaporate, leading to a decrease in mass. This process is known as dehydration.
When 20 g of mercury oxide is heated, it will decompose into oxygen and mercury. The combined mass of oxygen and mercury will still be 20 g, as no mass is lost or gained in a chemical reaction according to the Law of Conservation of Mass.
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 it oxidizes. The additional oxygen molecules it takes on when oxidizes leads it to have a higher mass.
When magnesium is heated, it undergoes a chemical reaction with oxygen in the air to form magnesium oxide. The total mass remains the same since no mass is lost or gained during a chemical reaction.
When magnesium is heated in air, it reacts with oxygen to form magnesium oxide. The total mass of the system, which includes the magnesium and the oxygen it reacts with, remains the same according to the Law of Conservation of Mass.
Nothing happens to the mass when its cooled (or heated).Mass is the same (law of Conservation of Mass).Volume can change, though, which affects density (since mass is constant).
it went up because the mass increases
The amount of mass does not change. The energy contained by the fixed mass increases.
These are changes in physical state, which are physical changes.
When a balloon is heated, the air inside the balloon expands and the molecules move faster, increasing their kinetic energy. This results in a decrease in mass density, as the molecules are more spread out. However, the total mass of the air inside the balloon remains the same.
When matter is heated it will expand
When air inside a balloon is heated, the molecules move faster, causing the air to expand and the balloon to inflate. The total mass of the air inside the balloon remains the same, but the density of the air decreases as it becomes less compact.
When a mass of air is heated, its molecules gain energy and move faster, causing the air to expand and become less dense. This warm air will then rise, creating a convection current that can lead to the formation of clouds, precipitation, and changes in weather patterns.
