True

Correct.

To determine the correctness of the statement, we can consider some common gases at room temperature:

1. Oxygen (O2) is a colorless and odorless gas at room temperature.
2. Nitrogen (N2) is a colorless and odorless gas at room temperature.
3. Carbon dioxide (CO2) is a colorless, odorless gas at room temperature.
4. Hydrogen (H2) is a colorless and odorless gas at room temperature.
5. Chlorine (Cl2) is a yellowish-green gas with a pungent odor.

The presence of chlorine contradicts the statement as it has both color and odor. Therefore, the statement "All gases are colorless and odorless at room temperature" is false.
