What is the highest temperature ever recorded on Venus?
What is the highest temperature ever recorded on Venus?
The highest point on Venus, Maxwell Montes, is therefore the coolest point on Venus, with a temperature of about 655 K (380 °C; 715 °F) and an atmospheric pressure of about 4.5 MPa (45 bar)….Atmosphere and climate.
| Venus Temperature | |
|---|---|
| Type | Temperature |
| Minimum surface temperature | 820°F (438°C) |
What is the minimum and maximum temperature of Venus?
Surface temperatures of the inner rocky planets
| Planet | Minimum surface temperature °F (°C) | Maximum surface temperature (°F (°C) |
| Mercury | – 275 °F (- 170°C) | + 840 °F (+ 449°C) |
| Venus | + 870 °F (+ 465°C) | + 870 °F (+ 465°C) |
| Earth | – 129 °F (- 89°C) | + 136 °F (+ 58°C) |
| Moon | – 280 °F (- 173°C) | + 260 °F (+ 127°C) |
What are the temperature extremes on Venus?
It appears that the surface temperature ranges from about 820 degrees to nearly 900 degrees F. The average surface temperature is 847 degrees F., hot enough to melt lead. No wonder the ocean basins are “dry”. At these temperatures any water would evaporate nearly instantaneously.
What temperature does water boil on Venus?
The boiling point of water on the surface of Venus would be around 300°C. It will boil normally turning to steam as the atmospheric pressure is below the critical pressure of water (218atm).
Is Venus hotter than Mars?
Mars is reddish color and some people might have guessed that Mars is the hottest planet in the solar system. Venus is the second planet from the sun and has a temperature that is maintained at 462 degrees Celsius, no matter where you go on the planet. It is the hottest planet in the solar system.
Which is hotter Venus or the sun?
Venus is the second planet from the sun and has a temperature that is maintained at 462 degrees Celsius, no matter where you go on the planet. It is the hottest planet in the solar system. This thick atmosphere makes the surface of Venus hotter because the heat doesn’t escape back into space.
Why is the temperature on Venus constant?
The blistering temperature on Venus is due in part to the oppressive atmosphere that is 100 times heavier than that of Earth. The greenhouse gasses that smother the planet create a uniform and constant temperature on all sides of Venus.
Will water boil at a higher or lower temperature on Venus?
Well, there isn’t any water on the surface of Venus, in form of rivers, lakes or oceans. The average temperature on Venus is 461.85 °C. Since water boils at 100 °C, it couldn’t be on the surface.
How much heat is required to superheat one pound of steam?
To superheat one pound of steam 12 degrees requires about 7 B. t. u. and if 1050 B. t. u. are required at the boiler to evaporate one pound of the saturated steam from the temperature of the feed water, the heat required for the superheated steam would be 1057 degrees.
What is the relationship between temperature and pressure in superheated steam?
However, with superheated steam there is no direct relationship between temperature and pressure. Therefore at a particular pressure it may be possible for superheated steam to exist at a wide range of temperatures. In general, saturated steam tables give gauge pressure, superheated steam tables give absolute pressure.
What is the degree of superheat after steam throttling?
For supply steam below 30 bar g in the dry saturated state, any drop in pressure will produce superheated steam after throttling. The degree of superheat will depend on the amount of pressure reduction.
Why is superheated steam not suitable for sterilization?
Superheated steam is not suitable for sterilization. This is because the superheated steam is dry. Dry steam must reach much higher temperatures and the materials exposed for a longer time period to have the same effectiveness; or equal F0 kill value. Superheated steam is also not useful for heating.
