Chemistry Concepts - Densities, Temperature Scales, and Scientific Notation

These flashcards cover key chemistry concepts related to densities of substances, temperature conversions, and scientific notation.

Density

The mass of a substance divided by its volume, commonly expressed in g/cm3.

Densest Element

Osmium is the densest element known, with a density of 22.6 g/cm3.

Gold Density

Gold has a density of 19.3 g/cm3, making it a heavy precious metal.

Mercury Density

Mercury is the only metal that is liquid at room temperature, with a density of 13.6 g/mL.

Kelvin Conversion

The Kelvin scale is derived from Celsius with the formula K = °C + 273.15.

Melting Point of Solder

The melting point of solder made from tin and lead is 224°C.

Boiling Point of Helium

Helium has the lowest boiling point of all elements at 452°F.

Scientific Notation

A way to express numbers as a product of a number between 1 and 10 multiplied by a power of 10.

Conversion Formula

Equations used to convert temperatures between Celsius, Fahrenheit, and Kelvin.
