Sunshine during the day heats the surface of the desert. That then heats the air above it. Since the desert has few clouds of high humidity to hold this heat after the sun sets, the heat radiates back into space and the desert cools down quickly.
Yes, it is the hottest during the day and cooles down durning the night. When it is night in the desert that's when all of the animals come out there.
The temperature cools down in the evening and at night when the sun sets and there is less direct sunlight.

They tend to feature small leaves, or leaves which roll up or close up in the heat. Some have a trunk or stem structure which funnels rainfall, dew and condensation down to the root system.
Physical weathering from temperature changes is most common on the shorelines, because waves are able to take down rocks that have been weathers. They would be least noticeable inland, in desert areas with little forestation.
The north-western part of India comprising the Indian Desert experiences the highest diurnal range of temperature. This is because of the fact that sand (found in ample quantity in this region) gains and loses heat very quickly. As a result of this phenomenon, there is a wide difference between day and night temperatures in this region. The day temperature may rise to 50°C and drop down to near 15°C the same night.
It is more like radiant heat, depending on the location of the desert. The Sonoran desert near Arizona/Mexico naturally is cooler at night after the sun goes down.
it goes into the minuses depending on the desert
Deserts typicaly cool down during the night time and the temperatures drop as the year progresses toward the winter months.
temperature goes down at night and as temperature decrease the air can hold less water vapor/moisture
Most hot deserts quickly cool down at night because there is little humidity and cloud cover to hold in daytime heating. The heat radiates back into space and the desert become quite cool at night.
There are hot and there are cold deserts, Antarctica included. Please narrow your question down to a particular location.
