Answer:
Viscosity is defined as the ability of liquid to resist its flow while fluidity refers to the tendency to allow its flow easily. ... A less viscous liquid will have more fluidity and vice versa.
Freezing is the change that occurs when a liquid changes into a solid as the temperature decreases. Melting is the opposite change, from a solid to a liquid as the temperature increases. ... Freezing is a change from a high energy state to one of lower energy, the molecules are moving less as their temperature falls.
