B.1 Flashcards 1

Front

Matter is made of particles with mass.

Back

Depending on the arrangement of the particles, energy, and intermolecular forces, matter can be classified as solids, liquids, or gases.

Front

Internal energy

Back

The total intermolecular potential energy plus the total random kinetic energy of the particles from their random motion.

Front

Density of a substance

Back

A measure of how much mass it has per unit volume, measured in kilograms per cubic meter (kg m⁻³).

Front

Solids vs. gases density

Back

Solids have the highest density, while gases have the lowest.

Front

Temperature scales in everyday life

Back

Degrees Fahrenheit (°F) and degrees Celsius (°C) are commonly used.

Front

Absolute temperature scale

Back

Scientists often use the Kelvin scale for absolute temperature.

Front

Absolute zero

Back

At 0 Kelvin, molecules of an ideal gas have zero energy, zero pressure, and zero volume.

Front

Converting Celsius to Kelvin

Back

Add 273 to the Celsius temperature.

Front

Temperature change equivalence

Back

A change of 1°C is the same as a change of 1 K.

Front

Absolute temperature definition

Back

The temperature in Kelvin of a substance is a measure of the average kinetic energy of its molecules.
