Explanation:
Room temperature is defined as the temperature that is about 25 degree celsius or 298 K.
When melting point of an object or substance is less than room temperature then it converts into liquid state at room temperature.
Since, it is given that substance "a" has melting point 280 K therefore, it is liquid at room temperature.
