because liquid can change shape and flow along pipes into the tube but it can't be squashed so it is able to move the piston out :)

When energy is removed from a liquid do the molecules move faster or slower?

I might be wrong, but I would say slower. If you mean energy in form of heat, molecules move slower if the liquid is colder, so if a liquid releases energy in form of heat (turns ¨cooler¨), than the molecules move slower. As I said, I might be wrong. Just my thoughts


What do molecules move faster in a solid liquid or gas?

Molecules move fastest in a gas, then in a liquid, and slowest in a solid. In a gas, molecules have high kinetic energy and move freely, while in a liquid, molecules can slide past each other but are still somewhat restricted. In a solid, molecules have the least amount of kinetic energy and vibrate in fixed positions.


How are the molecules in a gas different than the molecules in the liquid?

In a gas, molecules have higher kinetic energy, move more freely, and are spaced farther apart compared to a liquid. In a liquid, molecules are closer together, have lower kinetic energy, and move more slowly than in a gas.


How do molecules move during a phase change in a liquid to gas?

During a phase change from liquid to gas, molecules gain energy to overcome the intermolecular forces holding them together in the liquid state. As they absorb energy, molecules start to move faster and break free from their fixed positions, eventually leading to a transition to the less dense gas phase.


Why do liquids move?

The molecules in a liquid are spread out more than that of a solid. This allows the molecules to move freely in between the other molecules. All molecules move. They just move quicker in liquids because they have more space to go. Imagine this - A solid - A room with lots of people in, they all want to move somewhere but they can't because the room is too small and there's too many people in the room. A liquid - A room with lots of people in, the room is bigger and everybody has lots of space to move around. Understand??
