-245 because on the Celsius temperature scale the negative end is cold and the positive end is hot. So as you go more negative you get colder.
A gas at -245 degrees is colder than a gas at -143 degrees. Temperature is directly related to the average kinetic energy of particles in a substance, and the lower the temperature, the slower the particles are moving, making it colder.
Number of moles is 9,8355/T (T in kelvin).
Means the temperature of the gas is 170 degree Celsius
Means the temperature of the gas is 170 degree Celsius
Hydrogen becomes a solid at -434.5 degrees Fahrenheit
Hydrogen is a gas at 25 degrees Celsius.
i think mercury
It is a gas.
Gas mark 4 is equivalent to 176.67 degrees Celsius.
At 1000 degrees Celsius, oxygen exists in a gaseous state. Oxygen gas (O2) is a colorless and odorless gas at this temperature.
Bromine would be a gas at 2000 degrees Celsius, as it has a boiling point of 59 degrees Celsius.
Yes, oxygen is still a gas at negative 250 degrees Celsius. Oxygen has a boiling point of -183 degrees Celsius, so it would be a gas at -250 degrees Celsius.
