In which state of matter are particles moving the fastest? \( \begin{array}{llll}\text { a) Solid } & \text { b) Liquid } & \text { C) Gas } & \text { d) Plasma }\end{array} \) Which state of matter fills the shape of its container but maintains

Particles are zipping around the fastest in the gas state! In this state, they have plenty of energy to move freely and collide with each other and the walls of their container, resulting in high-speed motion that makes them quite the dynamic team. This rapid movement also explains why gases can easily expand to fill any space they occupy. Speaking of filling up spaces, liquids are like the reliable friends that know how to adapt! They take the shape of their container while still maintaining a certain volume. This is because the particles in liquids are close together, allowing them to slide past one another, which gives them the ability to flow and take on new shapes while keeping some stability.
