Oxygen and nitrogen are gases at room temperature, while carbon and mercury are not.
Mercury has a lower melting point compared to oxygen. Mercury melts at -38.83°C, while oxygen melts at a much lower temperature of -218.79°C.
At room temperature: Oxygen & Nitrogen are gases, Carbon is solid, & Mercury is a liquid.
Zinc and mercury are solids at room temperature, whereas oxygen and bromine are gases.
the physical state of oxygen at room temperature is GAS! - Joslyn ;*
oxygen's physical state is gas
Alcohol, mercury, gasoline, sulfuric acid, paint and VERY cold oxygen.
Gas
mercury
oxygen because it is a gas while oil,alcohol and mercury is liquid.
Mercury oxide can be separated by heating it to a high temperature, which leads to the decomposition of the compound into its elements: mercury and oxygen. The mercury vaporizes and can be collected, while the oxygen is released as a gas.
No, combustion of gasoline is a chemical change because it involves a chemical reaction between the gasoline and oxygen to produce carbon dioxide, water, and heat. A physical change involves a change in the physical state or appearance of a substance without altering its chemical composition.
