Front

What is the hypothesis regarding the distance water shoots from a bottle when mixed with detergent or coke?

Back

Water does not shoot further when mixed with detergent or coke.

Front

Which pigment has the lowest absorption rate at a wavelength of 500 nm?

Back

Chlorophyll A.

Front

How does molecular mass affect viscosity?

Back

Different molecular masses have differing viscosity levels.

Front

What occurs to the number of molecules escaping a liquid when the temperature is increased?

Back

As the temperature increases, more molecules escape the liquid.

Front

Define evaporation.

Back

Evaporation is the process by which molecules transition from the liquid phase to the gas phase.

Front

What is viscosity?

Back

Viscosity is a measure of a fluid's resistance to flow.

Front

Explain the relationship between temperature and molecular movement.

Back

As temperature increases, the kinetic energy of molecules increases, leading to faster movement.

Front

What is the significance of chlorophyll in plants?

Back

Chlorophyll is essential for photosynthesis, allowing plants to absorb light energy.

Front

What does it mean if a hypothesis is supported by experimental data?

Back

It means that the data collected aligns with the predictions made by the hypothesis.
