Why sublimation occurs
Conversion of solid directly into gases is called sublimation. sublimation occur due to no difference between melting point and boiling point
addition of salt to water increased boiling point
Pure water has 100-degree centigrade b.p any impurity increased b.p.more energy is required to overcome intermolecular forces of water molecules and salt
why gases have a high rate of diffusion than liquid
The distance between gas atoms has greater than liquid .so other gases have easily adjusted to atom space.
