Density and Measurement in Science

These flashcards cover key concepts related to density, mass, and measurement in science based on the provided lecture notes.

Gas Density

The mass of gas per unit volume, which changes with temperature and pressure.

Standard Conditions for Gas Density

0°C and atmospheric pressure are used to compare gas densities.

Effect of Temperature on Gas Density

Increasing temperature increases particle motion and decreases gas density.

Effect of Pressure on Gas Density

Increasing pressure forces particles closer together and increases gas density.

Calculating Density of a Liquid

Density = mass/volume, where mass is measured after finding the mass of the container.

Irregularly Shaped Objects Volume Calculation

Volume is measured by the displacement of liquid when the object is submerged.

Conversion between Mass Units

1 kg = 1000 g; to convert kg to g, multiply by 1000 and vice versa.

Definition of Mass

The amount of matter in an object, measured in kilograms or grams.

Density Equation

Density is calculated using the formula: density = mass/volume.

High Density vs. Low Density

High density substances have a large mass packed into a small volume, while low density substances have less mass in a larger volume.
