the diagram below shows the different phase transitions that occur in matter. which best describes the process that arrow 1 represents? molecules are speeding up during boiling. molecules are depositing as ice on a surface. molecules are slowing down during condensing. molecules are moving from stationary positions.
Answer
Brief Explanations:
The diagram illustrates the phase transitions between solid, liquid, and gas states of matter. Arrow 1 points from the liquid state to the gas state. This phase transition is known as boiling or vaporization. During boiling, the substance absorbs heat energy, causing its molecules to gain kinetic energy, move faster, and overcome intermolecular forces to escape into the gaseous phase. Therefore, molecules speed up during boiling.
Answer:
Molecules are speeding up during boiling.
