1 400 2 because it has large intermolecular force 4 because it has a value of 2260 5 because it in surface area we can dry our clothes by increasing surface area 7because it is used in breaking the force of attraction

1) The y substance has more intermolecular forces because it takes greater amount of heat for the melting process and melting is nothing but the disintegration of the solid molecules.
2)The surface area of ice is always greater than the water that's why ice causes more cooling than the water.
3)The matter's state conversion occurs in a particular temperature and this temperature remains constant ,untill the full conversion takes place.
4)Because evaporation only occurs on the external surface of a substance.
5) Because honey has a greater density than the ink.
6) Same explanation as question 3.
