Answer:

All the statements are true

Explanation:

Viscosity is affected by temperature. For example, if we put heat over some liquids like honey and syrup, they tend to flow more freely. On the other hand, if the temperature gets cold the viscosity tends to thicken (ex: engine oil of a car during winter). These examples make the first statement true: “Viscosity increases as temperature decreases”.  Viscosity is affected by pressure too. To see a change in a “molecular level”, the pressure needs to be very extreme. This make the second statement true: “Viscosity increases as molecular weight increases”. Taking in consideration both statements, we can conclude that the third statement is also correct. When viscosity is put into heat and little pressure, it tends to lessen, since the interaction between the molecules decreases and the intermolecular forces decreases. On the other hand, by default, when viscosity is put in a cold weather and pressure increases, the level of viscosity thickens, since the molecules start colliding and their motion becomes disorganized.

How many children does the average family in luxembourg have?
damaskus [11]
The average family in the country of Luxembourg, has 2 children. In 2016 a study showed that 32.2 homes had two children, while 155 households had no children. This may be attributed to the fact that currently in Luxembourg, most families no longer marry and more men and women are living separately. The marriage rate has rapidly declined, while the divorce rate has skyrocketed.
