Fluids can be which of the following states of matter?
Solids and liquids
Solids and gases
Liquids and gases
Answer explanation
Fluids are substances that can flow, which includes liquids and gases. Solids do not flow and therefore are not considered fluids. Thus, the correct answer is liquids and gases.

Out of the following fluids, which is the most viscous
Air
Corn syrup
Helium
Honey
Answer explanation
Honey is the most viscous fluid among the options. Viscosity measures a fluid's resistance to flow, and honey, being thick and sticky, has a higher viscosity compared to air, corn syrup, and helium.

What creates a fluid's viscosity
chemical reactions between particles
forces of attraction between particles
Answer explanation
A fluid's viscosity is primarily influenced by the forces of attraction between its particles. Stronger attractions lead to higher viscosity, as particles resist flow more than in fluids with weaker attractions.

What happens to the viscosity of a liquid when its temperature is DECREASED?
The viscosity of the liquid decreases
The viscosity of the liquid increases
The viscosity of the liquid stays the same
Answer explanation
When the temperature of a liquid decreases, its molecules move slower, leading to increased interactions and resistance to flow. This results in an increase in viscosity, making the liquid thicker.

What happens to the viscosity of a liquid when its temperature is INCREASED?
The viscosity of the liquid decreases
The viscosity of the liquid increases
The viscosity of the liquid stays the same
Answer explanation
When the temperature of a liquid increases, its molecules move faster, reducing intermolecular forces. This results in a decrease in viscosity, making the liquid flow more easily.

Orange juice has a...
Low viscosity
High viscosity
Answer explanation
Orange juice has a low viscosity, meaning it flows easily and is not thick. This characteristic allows it to be poured and consumed without difficulty, distinguishing it from liquids with high viscosity.

Lamp oil has a...
low viscosity
high viscosity
Answer explanation
Lamp oil is known for its low viscosity, which allows it to flow easily and be used effectively in lamps. High viscosity liquids are thicker and do not flow as freely, making 'low viscosity' the correct choice.
