The temperature might get that cold (-200°F or -129°C), but the observed minimum is only about -87°C (-125°F) which is pretty cold.

The temperature does change at night but it depends where you are.
If the temperature is 44F and the temperature drops 20 degrees, the temperature would be 24. Subtract the temperature drop from the starting temperature.

Yes. Temperatures cool at a rate about 6.5 Celsius degrees per kilometer of altitude. This is straight from a 6th grade book.
Mercury, the closest planet to the sun, fluctuates in temperature more than any other planet. During the day, its temperature can reach 800 degrees Fahrenheit (430 degrees Celsius), and during the night, its temperature can drop to -280 degrees Fahrenheit (-170 degrees Celsius). This is a drop of about 1,080 degrees Fahrenheit (600 degrees Celsius).
In the summer the temperature may drop into the 60s and 70s (degrees F.) at night. In the winter, 40s and 50s with a few nights that may drop below freezing in parts of the desert.
Cold winter deserts can drop well below 0 degrees F in winter. The Gobi has been known to drop to -40 degrees or even colder. The Antarctic Desert has had a temperature measured at -135.8 degrees F.

The average surface temperature of Mercury is approximately 800 degrees Fahrenheit (430 degrees Celsius). During the daytime, it can reach up to 800 degrees Fahrenheit (430 degrees Celsius), while at night, it can drop to around -290 degrees Fahrenheit (-180 degrees Celsius) due to its lack of atmosphere to retain heat.
The drop is 25 degrees.

The temperature on the planet may reach 840 degrees F (450 degrees C) during the day. But at night, the temperature may drop as low as -275 degrees F (-170 degrees C). It has the greatest temperature range of any planet or natural sattelite in the solar system.
