During a fun science experiment, Henley accidentally spills salt into a glass of water, and it magically disappears! What is this amazing property of salt called?
Conductivity
Density
Solubility
Intermolecular Attraction
Sophia and Vincent are conducting a sweet experiment. They notice that sugar dissolves faster in hot cocoa than in iced tea. What does this fun observation tell us about the role of heat?
Increases solubility
Decreases solubility
Has no effect on solubility
Creates a chemical change

During a fun science experiment, Leighton and Jackson are exploring the concept of intermolecular space. They notice that gases can be compressed more easily than liquids. What does this observation tell us about the intermolecular space in gases compared to liquids?
Gases have less intermolecular space than liquids
Gases have more intermolecular space than liquids
Gases and liquids have the same intermolecular space
Intermolecular space is irrelevant in this context
In a real-world science lab, Vivienne and Julian are learning about plasma. They discover that plasma is different from other states of matter. Which of the following is a unique characteristic of plasma?
Plasma has a definite shape
Plasma is electrically neutral
Plasma consists of charged particles
Plasma cannot conduct electricity
Henley and Logan are conducting a fun experiment with ice and water. Based on their data, which statement about the law of conservation of matter is correct?
The mass of matter changes after melting
The mass of matter stays the same before and after melting
The water weighs more than the ice
The ice weighs more than the water
Murphy and Skye are playing with magnets and notice that some materials stick together due to intermolecular attraction. Which of the following best describes intermolecular attraction?
The force that repels molecules from each other
The force that holds molecules together
The force that changes the state of matter
The force that increases the temperature of a substance
