• Liam (Kinetic energy)

• Arjun (Potential Energy)

Imagine Charlotte, Liam, and Kai are in a science lab. They are discussing bonds and Charlotte says, 'If a bond is polar, it has...'

• High potential energy

• Low potential energy

Noah, Hannah, and Luna are having a debate. They are trying to figure out which of the following bonds has the highest potential energy. Can you help them settle this?

• Carbon to hydrogen

• Nitrogen to hydrogen

• Oxygen to Hydrogen

• Nitrogen to Carbon

Sophia, Abigail, and Liam are having a heated debate. Sophia says that enthalpy is the cause of a molecule's pressure and volume. Is Sophia correct?
