Gaseous state
Yes, it is possible for methane.
The density of methane gas at +25 degrees Celsius is 0.656 kg/m3. The density of methane liquid -90 degrees Celsius is 162 kg/m3. The SI density standard is kg/m3.
At atmospheric pressure it will be a solid at temperatures below about -140 °C. At atmospheric pressures, it will be a liquid from about -140 °C to about 0 °C. It will be a gas above 0°C unless under pressure. Under moderate pressure (about 38.1 psia) it can be liquefied at 25 °C - which is why it is often used as the fuel in cigarette lighters.

At room temperature, mercury (Hg) is a liquid, and methane (CH4) is a gas. The melting point of methane is -182.5 degrees Celsius. The melting point of mercury is -39 degrees Celsius. It takes more heat to melt the mercury.
Sulphur is solid at 20 Celsius.
Mercury's state at 25 degrees Celsius is liquid.
