In MathJax, a space requires a backslash in front.

If you ventilate 15 minutes during a cold winter day, with all windows open, the room air temperature sinks very fast and can reach close to 0°C. Once you close the windows, the room temperature increases fast again, even without any heating, simply because the building has a much higher thermal mass than the air inside. | |
