Answer :
The molecules move faster at higher temperatures and overcome attractions more easily.
Correct answer choice is:
A. The molecules move faster at higher temperatures and overcome attractions more easily.
Explanation:
The gas viscosity will rise with temperature. According to the kinetic theory of gases, the viscosity should be proportionate to the square root of the ideal temperature, in an application, it rises further swiftly.
In a liquid, there will be molecular exchange alike to those produced in a gas, but there are added plentiful attractive, cohesive forces between the molecules of a liquid (which are very near concurrently than those of a gas). Both cohesion and molecular interchange add to liquid viscosity.
The consequence of raising the temperature of a liquid is to decrease the cohesive forces while concurrently raising the rate of the molecular variation.
