Explain how heat is exchanged through potential and kinetic energy

If i can still dissolve more sugar into the solution at a certain temperature what would i call that solution

Which diagram represents the phase tha occurs after a solid melts?

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
