Answer:A. the molecules move quicker at greater temperatures and also conquer attractions even more conveniently ">" data-test="answer-box-list">
You are watching: Which statement best explains why heating a liquid affects its viscosity?
The initially statement i.e. The molecules relocate much faster at higher temperature and conquer attractions more easily is the true statement bereason by enhancing temperature the kinetic power of molecules rises because kinetic energy is directly proportional to temperature so molecules start to move much faster and also their inter molecular pressures decrease it rises their collision cross sectional area and also this increasing collision price will certainly cause the increase of resistances in between them this resistances which a fluid experiences during its flow is called as viscosity.
