the diagram below shows the different phase transitions that occur in matter. which statement best describes the process that arrow 1 represents? molecules are speeding up as boiling occurs. molecules are slowing to a stop while freezing. molecules are slowing down during condensation. molecules are vibrating in 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 transition is known as vaporization (or boiling, if occurring at the boiling point). During vaporization, the substance absorbs energy, which increases the kinetic energy of its molecules. Consequently, the molecules move faster and transition into the gaseous phase. Therefore, the statement that best describes this process is that molecules are speeding up.
Answer:
Molecules are speeding up as boiling occurs.
