1)This is a 5 part question. The first is realizing that 20F to 32F uses .5BTU per pound per degree. That means it takes 32-20=12*.5=6BTUs to get the ice to 32F. 2)Then you need to know the Latent Heat of Fusion for Ice which is 144BTUs (given). Lets assumes the ice changes from ice to water instantaneously at 32F. 3)Next we calculate the BTUs from 32F to 212F. Which is 1BTU per pound per degree F. 212-32=180 so it take 180BTUS. 4)Next we have to use the Latent Heat of Vaporization of water which will say instantaneously converts water to vapor. This takes 970BTUS (given). 5)Then we calculate the BTUS from 212F to 220F. Which is .5BTUs per pound per degree F which is 220-212=8*.5=4BTUs...... Finally add up all the BTUs and you get 6+144+180+970+4=1304BTUs.
Would it temperature be higher or lower than the temperature of Earth?
It depends on the specific planet in question. Some planets may have higher temperatures than Earth (such as Venus with its extreme greenhouse effect), while others may have lower temperatures (such as Mars which has a thin atmosphere leading to colder average temperatures).
What is the temperature of 250 degrees Celsius on the kelvin scale?
To convert from Celsius to Kelvin, you add 273.15. So, 250 degrees Celsius is equal to 523.15 Kelvin.
What is the freezing point and boiling point of water on the Fahrenheit scale?
According to Fahrenheit scale, freezing point of water is 32 degrees Fahrenheit (°F) and boiling point is 212 °F
What is -27 Fahrenheit degrees is Celsius?
-27 F = -32.78 C

What temperature doess mdf board burn at?
MDF board is composed of wood fibers and resin, so it typically burns at temperatures similar to solid wood, which is around 450-500°F (232-260°C). However, the resin in MDF may emit toxic fumes when burning, so it is important to avoid exposure to smoke from burning MDF.
Is Lithium at room temperature solid liquid or gas?
Lithium is a metal. It is soft and is a nice shiny silvery colour when first cut. It is very reactive.
How do you change celsius to Fahrenheit on safety first ear thermometer model 49501?
To change the temperature unit from Celsius to Fahrenheit on the Safety 1st ear thermometer model 49501, typically you would press and hold the power button for a few seconds until you see the unit symbol flashing. Then use the scan button to switch between Celsius and Fahrenheit and press the power button to confirm your selection. Refer to the user manual for specific instructions for your model.
What is the word for the process in which water in a rock cracks and expands in low temperatures?
The process you are referring to is called frost wedging. It occurs when water seeps into the cracks of rocks, freezes, and expands, putting pressure on the rock and causing it to crack and break apart.
Why are hyper thermophiles that grow at temperatures above 100C seemingly limited to oceanic depths?
Hyperthermophiles that grow at temperatures above 100°C are limited to oceanic depths because these extreme temperatures are usually found at hydrothermal vents deep in the ocean where conditions are suitable for their survival. These organisms have evolved to thrive in these high-temperature environments and are adapted to the unique conditions present in oceanic depths, such as high pressure and specific chemical compositions. Additionally, the presence of these hyperthermophiles in oceanic depths is linked to the availability of energy sources and nutrients that are provided by the hydrothermal vent ecosystems.
What is -285 degrees Fahrenheit in Celsius?
285 °C is equal to 545 °F
The conversion formula is °F = (9/5 °C)+ 32
Why are bodies of water sometimes warmer than the temperature on land?
Water is slower to absorb and release heat than the surrounding area. That is why water is typically cooler in the summer and warmer in the winter. A lot of this also depends on the geogrpahy of the area.
How is the Celsius scale calibrated?
Generally thermometers are calibrated two ways . primary calibration or Secondary calibration.
In secondary calibration , two thermometers are kept side by side under same conditions and identify the difference with respect to one thermometer.
In primary calibration , thermometer that to be calibrated is placed in a ice cubes made of pure distilled water . Now pour some distilled water and stirr well . Now place thermometer inside that mixture
This will give the Melting point temperature of pure water 0 degree centigrade. Now see the reading on thermometer and adjust reading.
This way of calibrating a thermometer is accurate enough form most applications.
When water is confined under pressure greater than normal atmospheric pressure,
a higher temperature is required to make it boil. Higher pressure can be created
simply by sealing the container the water is in ... that's how pressure cookers work.
Just seal the water in a container that can stand the pressure required to raise the
boiling point to 1,000 degrees, keep adding heat, and you'll get there.
NOTE:
DO NOT try this at home. You don't know what pressure is required, you
don't know how much pressure your container can stand, and you have no
way to measure the temperature of the water in it. If you put water in a
sealed container and heat it, the only thing that can be guaranteed for sure
is that your container will explode, and the stronger the container is, the more
violent the explosion will be.
What property is described by alchohal boils at 60 degrees?
The property described by alcohol boiling at 60 degrees C is the boiling point.
What matter takes this form below 0 degrees Celsius?
Yes! Clean water can exist in liquid phase even if temperature is under 0 degrees of Celsius temperature scale. This phenomenon is called Liquid hypothermia I think.
If clean, distilled water is left to cool down below 0 degrees in a very calm environment, that is if it is not disturbed in any way, and if container in which this water is, is clean, and without a scratch (dust particles can gather on a scratch), than
this may happen.
How do you change the digital temperature to Fahrenheit in a 2006 tiburon?
To change the temperature unit in a 2006 Tiburon to Fahrenheit, first press and hold the "SET" button on the climate control panel. While holding the button, use the "UP" or "DOWN" arrow button to change the unit from Celsius to Fahrenheit. Release the "SET" button to confirm the change.
What city had lowest recorded temperature yesterday?
As far as I know, it would be Alaska with -80 and that's with NO windchill factor

What is the lowest water temperature safe to swim in?
The lowest water temperature considered safe for swimming without a wetsuit is around 70°F (21°C). Below this temperature, there is an increased risk of hypothermia and rapid heat loss from the body, especially if the swim extends for a prolonged period. It is always advisable to use caution and consider individual tolerance levels when swimming in cold water.
