Mean temperature is 442.5 K (169C, 336F) and ranges from 100K (-173C, -279F) on the dark side to 700K (426C, 800F) on the sunny side
Mercury
It is at least 250 to 300 degrease
350 degrees in the day time 170 degrees in the night time
Assuming "Room Temperature" is fairly constant (i.e not fluctuating dramatically) and the sample of Mercury has had time to equilibriate with it's surroundings, then the temperature of the Mercury will be the same as "Room Temperature".. what ever that happens to be at the time.
Day time 600-750 degrees Fahrenheit Night time 150 - -100 degrees Fahrenheit
Bloody hot in the day and hot at night
The average surface temperature on Mercury is around 700 K (426.85°C). However, temperatures can vary greatly depending on the location and time of day due to Mercury's lack of atmosphere to regulate heat.
It is approx 700 K.
The average temperature on Mercury can vary dramatically, ranging from about -280°F (-173°C) at night to around 800°F (427°C) during the day due to its thin atmosphere and lack of significant heat retention.
because mercury is extremely hot during the day and extremely cold at night
The temperature range of the planet Mercury is from 350 degrees in the daytime to 170 degrees at the nigh-time. The temperature range of the metal mercury is from −38.83 °C to 356.73 °C.
No, it varies by a huge amount.
