Density and Temperature Scales

Vocabulary flashcards covering fundamental concepts, formulas, and values for density and temperature scales.

Density

A measure of mass per unit volume ($\text{density} = \frac{\text{mass}}{\text{volume}}$), which indicates how much mass a substance has relative to the volume it occupies.

Intensive Property

A property, such as density, that is independent of the size or amount of the sample and can be used to identify substances.

Fahrenheit Scale

A temperature scale on which water freezes at $32\,^\circ\text{F}$ and boils at $212\,^\circ\text{F}$.

Celsius Scale

A temperature scale on which water freezes at $0\,^\circ\text{C}$ and boils at $100\,^\circ\text{C}$.

Kelvin Scale

The SI temperature scale on which water freezes at $273.15\,\text{K}$ and boils at $373.15\,\text{K}$.

Absolute Zero

The coldest possible temperature, defined as $0\,\text{K}$ on the Kelvin scale.

Fahrenheit to Celsius Conversion Formula

The mathematical equation used to convert degrees Fahrenheit to degrees Celsius: $T_C = (T_F - 32) \times \frac{5}{9}$.

Celsius to Fahrenheit Conversion Formula

The mathematical equation used to convert degrees Celsius to degrees Fahrenheit: $T_F = \frac{9}{5} T_C + 32$.

Celsius to Kelvin Conversion Formula

The mathematical equation used to convert degrees Celsius to kelvins: $T_K = T_C + 273.15$.

Density of Water at $4\,^\circ\text{C}$

$$1.000\,\text{g/mL}$$

Density of Water at $25\,^\circ\text{C}$

$$0.997\,\text{g/mL}$$

Density of Mercury

$13.53\,\text{g/mL}$ at $25\,^\circ\text{C}$.

Normal Body Temperature

$98.6\,^\circ\text{F}$ on the Fahrenheit scale.
