Is this statement accurate?
the boiling point of the distilled water was 99°C. After five minutes, the temperature still stayed the same; it remained constant. The liquid was becoming a gas. Phase change means there is an energy change. When the temperature of the water started to increase and energy was added, the particles were starting to move. When the temperature stopped increasing and stayed constant, the particles were overcoming the intermolecular forces. The intermolecular forces were breaking apart. Energy needed to be added to overcome the particle’s motion energy, or kinetic energy.
I'm doing a lab about intermolecular forces and phase changes. We boiled water
It is accurate
Thank you!
Yes, the statement is accurate. It describes the process of boiling water and the associated phase change and intermolecular forces.
To explain further, when water reaches its boiling point, it starts to undergo a phase change from a liquid to a gas. During this process, energy is absorbed in the form of heat, which causes the water molecules to gain enough kinetic energy to break the intermolecular forces holding them together. As energy continues to be added, the water molecules move faster and faster, transitioning into a gaseous state.
The statement correctly notes that phase changes involve an energy change. When the temperature of the water remains constant at the boiling point, it means that the energy being added is being used to overcome the intermolecular forces rather than increasing the temperature further. This is why the temperature plateaus during boiling.
Furthermore, the statement accurately mentions that the intermolecular forces between water molecules are breaking apart during the phase change. These forces, such as hydrogen bonding, hold the water molecules together in the liquid state. Overcoming these intermolecular forces requires the addition of energy to break their bonds and transition into a gas.
Overall, the statement provides a good explanation of the process of boiling water and the role of intermolecular forces in a phase change.
