When you add energy to a system, its temperature increases and the particles within it move faster. This can result in an increase in kinetic energy and changes to the system's physical state. Conversely, when you subtract energy from a system, its temperature decreases and the particles move more slowly, potentially causing changes in phase or state.

What do you add or subtracting to change a state of matter?

To change the state of matter, you need to add or remove energy. For example, to change a solid to a liquid, heat is added to increase the temperature until it reaches the melting point. Likewise, to change a liquid to a gas, heat is added to increase the temperature until it reaches the boiling point.


What is it when you add or subtract an electron to an atom?

When you add an electron to an atom, the atom becomes negatively charged and is called an anion. When you subtract an electron from an atom, the atom becomes positively charged and is called a cation.


How do you change one state of matter to another?

To change one state of matter to another, you need to either add or remove heat energy. For example, to change a solid to a liquid, you would need to add heat energy to melt the solid. Similarly, to change a liquid to a gas, you would need to add heat energy to evaporate the liquid.


What happens when you add heat in a substance?

When heat is added to a substance, its molecules gain energy and move faster, causing the substance to increase in temperature. This can lead to changes in physical state, such as melting or boiling, depending on the substance's properties. In some cases, chemical reactions may also occur due to the increased thermal energy.


What happens when you add sulfur to oxygen?

When sulfur is added to oxygen, they can combine to form sulfur dioxide (SO2) gas. This reaction is exothermic and releases heat energy. Sulfur dioxide is a colorless gas with a sharp, pungent smell.
