write this in 2 sentences

Answer 1

The pressure inside the closed jar will increase because as the solid melts, it will occupy a larger volume as a liquid compared to its solid state. Additionally, if the jar is sealed and the volume of the jar remains constant, the increase in the number of moles will also contribute to an increase in pressure according to the ideal gas law.
