Q: Give an example of a solid material.
Examples of solid materials are building, stone, and tin box.
Q: What is a liquid?
A liquid is a material that does not retain its fixed shape, and its matter is made of more loosely packed particles. It will take the shape of its container.
Q: How do particles behave in a liquid?
Particles can move about within a liquid, but they are packed densely enough that volume is maintained.
Q: What is a liquid?
A liquid is a material that can be poured, has flow, takes the shape of its container, takes up space, has weight, and has a fixed volume.
Q: What is a gas?
A gas is a material that has neither a defined shape nor a defined volume, and it assumes the shape and volume of its container. It can flow and expand to fill all the space available to it.
Q: Can a gas be compressed?
Yes, a gas can be compressed. When a gas is compressed, its molecules huddle together and may eventually bond to form a liquid or solid.
Q: How do particles behave in a gaseous state when heated or cooled?
When a sample of matter in the gaseous state is heated, the atoms or molecules gain energy and move more rapidly. When a sample of gaseous matter is cooled, the atoms or molecules lose energy and move more slowly.
Q: What are the conditions that can cause matter to change its form?
Matter can change its form under certain conditions like heating or cooling.
Q: How does heating affect the molecules of a substance?
Heating increases the temperature of a substance, causing its molecules to gain energy and move more rapidly, resulting in a change in state.
Q: What happens to most solids when they are heated?
Most solids melt into a liquid when they are heated, as the heat causes the molecules to absorb energy and become freer, moving apart from one another.
Q: What happens when a liquid is heated?
When a liquid is heated, its temperature rises and molecules absorb heat to become freer and move apart, eventually turning into a gas.
Q: What happens when a liquid is frozen?
When a liquid is frozen, its molecules give up their heat and settle closer together, causing the liquid to become solid and hard.
Q: What are changes in state of matter?
Changes in state of matter refer to the transformation of matter from one state (solid, liquid, or gas) to another due to changes in temperature or pressure.
