What is hydrogen state at 20c?
At 20°C, hydrogen is in a gaseous state. It remains as a colorless, odorless gas at this temperature.
Which is colder -20C or -20F?
-20F is colder than -20C. This is because the Fahrenheit scale has a smaller degree interval than the Celsius scale, so -20F is a lower temperature than -20C.
What is between 20c and -15?
35

What the range temperatures of Earth's surface?
From -20C to 50 C From -20C to 50 C
Substances that can be transformed to a gas at relatively low temperatures are termed?
Substances that can be transformed into a gas at relatively low temperatures are called volatile substances. These substances have weak intermolecular forces that allow them to readily transition from a liquid or solid state to a gas at lower temperatures compared to non-volatile substances.
What is the movement of substances?
any gas
