Densidad

The video explains how density changes as a function of temperature and pressure, noting that generally, increasing temperature or reducing pressure decreases density. However, water is an exception, being densest at 4 °C, and less dense if the temperature increases or decreases from this point.

What factors influence the variation of density?

• Temperature and pressure

• Volume and mass

• Color and texture

• Shape and size

What generally happens to density when temperature increases?

• It fluctuates randomly

• It decreases

• It remains constant

• It increases

How does reducing pressure affect density?

• No effect on density

• Causes density to fluctuate

• Decreases density

• Increases density

At what temperature is water most dense?

• 4°C

• 10°C

• 0°C

• 100°C

What happens to the density of water if the temperature deviates from 4°C?

• It becomes unpredictable

• It becomes more dense

• It becomes less dense

• It remains unchanged
