Describe what is happening in regards to the heat energy, temperature, molecular potential energy, and molecular kinetic energy when water is boiling.
If you will tell me what your trouble is perhaps I can help get you started but I don't want to write your paper for you.
When water is boiling, several changes are occurring in relation to heat energy, temperature, molecular potential energy, and molecular kinetic energy.
1. Heat energy: Heat energy is being supplied to the water from an external source, such as a stove or a fire. This heat energy is responsible for raising the temperature of the water and driving the process of boiling.
2. Temperature: As the heat energy is supplied to the water, the temperature of the water increases. This rise in temperature is a result of the molecular kinetic energy, or the energy associated with the motion of water molecules, increasing.
3. Molecular potential energy: As the water temperature increases, the molecular potential energy also increases. Molecular potential energy refers to the potential stored energy within the intermolecular bonds that hold water molecules together. With increased temperature, these intermolecular bonds start to loosen.
4. Molecular kinetic energy: As the temperature continues to rise, the molecular kinetic energy of the water molecules also increases. This means that the motion of the water molecules becomes more vigorous and fast-paced. At boiling point, the water molecules have gained enough kinetic energy to overcome the intermolecular forces holding them together.
When water reaches its boiling point, which is 100 degrees Celsius or 212 degrees Fahrenheit at standard atmospheric pressure, it undergoes a phase transition from liquid to gas. The process of boiling occurs as the water molecules gain enough kinetic energy to break free from the liquid phase and enter the gaseous phase.
In summary, when water is boiling, heat energy is supplied to increase the water temperature, which in turn increases the molecular potential and kinetic energy of the water molecules. Eventually, the water molecules gain enough kinetic energy to overcome the intermolecular forces and transition to the gas phase.
