Answer 1

The best procedure for comparing the electrostatic forces between the molecules of different substances would be to heat each substance in solid form to its melting point and measure the quantity of each substance that has melted.

This approach directly assesses the strength of the intermolecular forces (including electrostatic forces) since the amount of heat required to melt a substance (the enthalpy of fusion) reflects the strength of the forces holding its molecules together in the solid state. By comparing the quantities that have melted for different substances, you can infer differences in the electrostatic forces between their molecules.
