The Correct Answer and Explanation is:
Here are the correct answers for each statement:
- Matter is anything that has mass and takes up space.
- The three basic states of matter are solid, liquid, and gas.
- A state change is a physical change.
- Matter changes state because of temperature and pressure; however, chemical properties do not change.
- Ice gives water molecules energy that causes them to vibrate faster, breaking their bonds and melting.
- Heat energy that helps break the molecular bonds of a solid is heat of fusion.
- The temperature at which a liquid turns into a gas is the boiling point.
- Sublimation is when a solid turns directly into a gas.
Explanation:
- Matter: Matter is defined as anything that has mass and occupies space. This includes solids, liquids, and gases, all of which are different forms that matter can take.
- States of Matter: The three fundamental states of matter are solid, liquid, and gas. Each state is defined by how the particles of matter are arranged and how they move.
- In a solid, particles are tightly packed and only vibrate in place.
- In a liquid, particles are close together but can move around, allowing the liquid to flow.
- In a gas, particles are far apart and move freely, making the gas easy to compress and expand.
- State Change: A state change (like melting or freezing) is a physical change because it doesn’t change the chemical composition of the substance, just its physical state.
- State Changes and Temperature: Matter changes state due to changes in temperature or pressure. For example, when heat is applied to ice (a solid), the particles move faster and break free from their fixed positions, causing the ice to melt into liquid water. Despite this change, the chemical properties of water remain the same.
- Ice and Water Molecules: Water molecules in solid form (ice) are arranged in a crystal structure. When heat energy is applied, the molecules vibrate more rapidly, breaking the bonds and allowing the solid to transition into a liquid (melting).
- Heat of Fusion: The heat of fusion is the energy required to change a substance from a solid to a liquid at its melting point, helping to break the molecular bonds in the solid.
- Boiling Point: The boiling point is the temperature at which a liquid changes into a gas. For water, this occurs at 100°C at standard atmospheric pressure.
- Sublimation: Sublimation is the process where a solid changes directly into a gas without passing through the liquid state. An example is dry ice (solid carbon dioxide) turning into gas without melting.
