Understanding Ketchup's Non-Newtonian Behavior

The video explores the unique behavior of ketchup, a Non-Newtonian fluid, which behaves differently under varying forces. Unlike Newtonian fluids, ketchup's viscosity changes with force and time. The video explains the science behind this behavior, including the role of tomato particles and the impact of ingredients like xanthan gum. It also provides practical tips for pouring ketchup effectively.

What makes it difficult to pour the right amount of ketchup?

• Its solid-like behavior

• Its sweet taste

• Its liquid-like behavior

• Its unpredictable behavior

Which of the following is a Newtonian fluid?

• Peanut butter

• Mayonnaise

• Water

• Ketchup

Which of the following is NOT a Non-Newtonian fluid?

• Water

• Blood

• Paint

• Toothpaste

What is a characteristic of Non-Newtonian fluids like ketchup?

• Their thickness changes with force

• They evaporate quickly

• They always flow at the same rate

• They are always thicker than water

How does ketchup behave when a strong force is applied quickly?

• It becomes thicker

• It remains solid

• It flows easily

• It evaporates

What is the primary component of the liquid surrounding tomato particles in ketchup?

• Water

• Sugar

• Vinegar

• Oil

What happens when a weak force is applied to ketchup for a long time?

• It thickens

• It evaporates

• It flows

• It solidifies

What is one possible explanation for ketchup flowing under a weak force over time?

• Particles solidify

• Water acts as a lubricant

• Particles evaporate

• Particles dissolve completely

Which ingredient can affect the behavior of different ketchups?

• Salt

• Xanthan gum

• Garlic

• Pepper

What is a recommended method for pouring ketchup smoothly?

• Keep the lid on and shake, then pour

• Shake the bottle continuously

• Hit the bottle hard

• Use a spoon
