Why does the temperature vary on Mercury?
But on Mercury, the planet has essentially no tilt, which means that the hemispheres experience no significant difference in temperature from one another. That allows Mercury, the closest planet to the sun, to hang onto ice at its surface.
Why are Mercury’s day and night temperatures so different?
Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C). Without an atmosphere to retain that heat at night, temperatures can dip as low as -290°F (-180°C). The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth’s Moon.
Why is one side of Mercury hot and the other cold?
Mercury has almost no atmosphere. Because it is so close to the sun, it can be very hot. On its sunny side, Mercury can reach a scorching 800 degrees Fahrenheit! On its dark side, Mercury gets very cold because it has almost no atmosphere to hold in heat and keep the surface warm.
What is the temperature on the dark side of Mercury?
111 degrees +/-
The average dark-side temperature is 111 degrees +/- 3 degrees K. The thermal inertia of the surface required to fit this temperature is close to that for the moon and indicates that Mercury and the moon have very similar top surface layers.
What is the coldest temperature on Mercury?
-290 degrees Fahrenheit
Mercury rotates slowly and has a thin atmosphere, and consequently, the night-side temperature can be more than 1,000 degrees Fahrenheit lower than the day-side temperature shown on the diagram. It can be as cold as -290 degrees Fahrenheit (-179 degrees Celsius) on Mercury at night.
What is the hottest temperature ever recorded on Mercury the planet?
801 Fahrenheit
Mercury’s temperatures can go between -279 Fahrenheit (-173 Celsius) at night to 801 Fahrenheit (427 Celsius) during the day. (This is hot enough to melt lead!)
Why is Venus the hottest planet instead of Mercury?
Venus is so bright because it is covered by clouds that reflect much of the incoming sunlight. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.
Why does Mercury have no rings?
Unfortunately, Mercury could never get rings like this. That’s because it’s too close to the Sun. The powerful solar winds blast out from the Sun, and would melt and destroy any icy rings around Mercury.
What made Mercury not a livable planet?
Mercury’s surface temperature reaches a scorching 430 degrees Celsius [800 degrees Fahrenheit] during the daytime, and in the absence of an atmosphere, it plummets to -180 degrees Celsius [-290 F] at night. So, its surface environments have rightfully been out of scientific consideration as a possible host of life.
Is Mercury hotter than Venus?
It is about the same size and made of the same rocky materials. It also comes closer to us than any other planet. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.
How come Mercury is not the hottest planet?
Since Mercury lacks an atmosphere, it has no way of trapping the heat that is generated by the sun, thus leading it to have periods of both hot and cold. Though it isn’t the hottest planet, it is still comes in a respectable second place, even without an atmosphere.
What kind of engine does a Mercury Zephyr have?
Zephyr buyers could choose between a 2.3-liter straight-four, a 3.3-liter straight-six, and a 5.0-liter V8, rated at 88, 85, and 134 horsepower, respectively (the six offered 154 lb-ft of torque versus the Pinto four’s 118, so it wasn’t quite as miserable a choice as the lackluster horsepower number suggests). This car has the V8.
What kind of sensor does a mercury thermometer use?
Some thermometers use a bulb filled with a chemical such as mercury as the temperature sensor. But some thermometers also use digital sensors. The visible sale is often a glass tube marked with a temperature range. Sometimes, it is a digital readout.
What are the disadvantages of a mercury thermometer?
Disadvantages of Mercury Thermometer 1 Cannot measure low temperatures 2 Hazardous if the bulb is broken and mercury leaks out 3 High price 4 Slow response
What was the cost of a 1978 Mercury Zephyr Z 7?
This car has the V8. The top-of-the-line factory audio system for the ’78 Z-7 played 8-track tapes, of course, and it cost a breathtaking $243 (about $1,000 in 2019 dollars). Just the thing for listening to Sweet!
What kind of engine did Mercury Zephyr have?
The Mercury Zephyr was introduced for the 1978 model year. The Zephyr was based on the Ford Fairmont, and was sold as a coupe, sedan, or station wagon. Engine options for the Zephyr incuded inline four, inline six, and V8 units.
Is the Mercury Zephyr the same as the Ford Fairmont?
From the 1978 to 1983 model years, the Mercury Zephyr served as the Mercury counterpart of the Ford Fairmont. The third vehicle to use the nameplate within Ford Motor Company, the Mercury Zephyr shares its nameplate with the 1936–1940 Lincoln-Zephyr and the 1950–1972 Ford Zephyr (produced by Ford of Britain).
Where can I find a 1978 Mercury Zephyr Z 7?
Here’s a tan-beige-brown Zephyr Z-7 in a Northern California self-service wrecking yard. The Z-7 came with plenty of Malaise Era decorative stuff, including “ rich, Corinthian Vinyl” bucket seats, paint stripes, and this disco-style hood ornament.
What’s the average temperature on the day side of mercury?
The day side of the planet reaches temperatures of up to 800 degrees Fahrenheit (427 degrees Celsius). In contrast, the chilly night side can get as cold as minus 290 F (minus 180 C). The planet has an average temperature of 332 F (167 C). These variations are relatively long-lived.
