Which material has the lowest viscosity?

acetone (fingernail polish remover)

motor oil

glue

syrup

Option (a) is the correct answer.

Explanation:

Viscosity is defined as the ability of a substance to have difficulty in changing its shape or difficulty in the movement. This means that a substance which is able to flow easily will have low viscosity.

For example, acetone has low viscosity as it is a volatile substance.

On the other hand, a substance that is able to flow with difficulty will have high viscosity.

For example, glue, syrup, motor oil etc are substances that find difficulty in flowing. Hence, they have high viscosity.

Thus, we can conclude that out of the given options acetone (fingernail polish remover) is the material has the lowest viscosity.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
