Is 89 degrees Fahrenheit hot?

Personally, this would be very warm for me. I live in California so I am used to this weather in the summer/spring. If you live int he west, then this weather should be warm but not hot :)

What is 145 degrees Fahrenheit in celcious?

Conversion from Fahrenheit to Celsius is done in three steps:

1. Subtract 32 from value in degrees Fahrenheit.

2. Multiply result of step 1 by 5.

3. Divide result of step 2 by 9.

Conversion formula: [°C] = ([°F] - 32) * 5 / 9 = (145 - 32) * 5 / 9 = 62.77 °C

What is -40C in F?

-104

INCORRECT

-40 C is also -40 F

It is the only point on the two different scales where the reading is the same.

-40 C = (-40 x 9/5) + 32 = -40 F

How hot is 24.4 Celsius to Fahrenheit?

24.4 degrees Celsius is equivalent to 75.92 degrees Fahrenheit.

What is 99.7 degrees Fahrenheit in celsius?

Conversion from Fahrenheit to Celsius is done in three steps:

1. Subtract 32 from value in degrees Fahrenheit.

2. Multiply result of step 1 by 5.

3. Divide result of step 2 by 9.

Conversion formula: [°C] = ([°F] - 32) * 5 / 9 = (99.7 - 32) * 5 / 9 = 37.61 °C 99.7 degrees Fahrenheit = 37.6111111 degrees Celsius

What is the difference in 20 degrees Celsius and 50 degrees Celsius?

50 - 20 = 30 degrees

20 is (30) less than 50

and 50 is (30) more than 20

hence difference is 30.

What does -20 centigrade equals in Fahrenheit?

Conversion from Centigrade (Celsius) to Fahrenheit is done in three steps:

1. Multiply value in degrees Celsius by 9.

2. Divide result of step 1 by 5.

3. Add 32 to result of step 2.

Conversion formula: [°F] = [°C] * 9 / 5 + 32 = -20 * 9 / 5 + 32 = -4 °F

How can you convert the 100 F to C?

[°C] = ([°F] − 32) × 5⁄9

100 degrees Fahrenheit = 37.78 degrees Celsius

What is the value of 100s degree C of Kelvin?

100 degrees Celsius = 373.15 Kelvin

Formula: [K] = [°C] + 273.15

What would be the final temperature if you mixed a liter of 30 degrees celsius water with 1 liters of 50 degrees celsius water?

A typical question...

Assuming no heat loss to the surroundings,

McDO = mcdo

Mass is proportional to volume. (Mass = density x volume)

=> MDO = mdo

=> 1 x (40 - O) = 2 x (O - 20)

=> 30 = 80

=> O = 26.7 oC (ANS)

What is 29.5 Celsius converted to fahrenheit?

29.5°C = 85.1°F: 29.5°C multiplied by 1.8 +32 = 85.1°F

What is the equivalent of -40celsius in Fahrenheit scale?

Conversion from Celsius to Fahrenheit is done in three steps:

1. Multiply value in degrees Celsius by 9.

2. Divide result of step 1 by 5.

3. Add 32 to result of step 2.

Conversion formula: [°F] = [°C] * 9 / 5 + 32 = -40 * 9 / 5 + 32 = -40 °F

Which group of people most often use Kelvin scale?

Yes, the Kelvin scale is very widely used in the sciences because it provides an absolute temperature scale as opposed to the relative scales like Celsius and Fahrenheit. In the world of cryogenics, particularly that of the really low temperatures, those nearer absolute zero, we see the Kelvin scale used frequently. To cite a single example, it is easier to talk about the boiling point of helium being 4.22 K rather than −268.93 °C, or −452.07 °F.

Is 76 degrees hot enough to wear shorts?

That depends on your personal preference and the local climate. 76 degrees Fahrenheit is typically warm enough for most people to wear shorts comfortably. If you feel warm enough to wear shorts and it is appropriate for the setting, then go for it!

Why do people use liquid crystal thermometers to take the temperatures of young babies?

Liquid crystal thermometers are often used to take the temperatures of young babies because they are quick, safe, and non-invasive. They do not require insertion into the baby's body, making them more comfortable for young children. Liquid crystal thermometers also provide a continuous temperature reading, allowing caregivers to monitor changes quickly.

What is minus 77 degrees Fahrenheit in celsius?

(-77) degrees Fahrenheit = -60.5555556 degrees Celsius

What growth temperature is the temperature at which an organism exhibits the highest growth rate?

The growth temperature is the temperature at which an organism exhibits its highest growth rate. Each organism has an optimal growth temperature range where it grows best, with temperatures outside this range resulting in lower growth rates.

Why do alcohols have a higher boiling point than the equivalent alkanes?

The polarity of the molecules determines the forces of attraction between the molecules in the liquid state. Polar molecules are attracted by the opposite charge effect (the positive end of one molecule is attracted to the negative end of another molecule. Molecules have different degrees of polarity as determined by the functional group present.

Principle: The greater the forces of attraction the higher the boiling point or the greater the polarity the higher the boiling point.

alcohol=because of inter molecular force eg : hydrogen bonding,van der waals dispersion forces and dipole-dipole interaction that have the capabilities. This attraction are stronger as the molecule get longer and have more electron and also the presence of only one oxygen vs. the two in the acid functional group.

What does 99 degree Fahrenheit equal in Celsius?

99 degrees Fahrenheit is equal to about 37.2 degrees Celsius.

What is 83 degrees converted to Fahrenheit?

u r soo unbelievably dumb. 83 degrees is a temperature, what temp. scale are u talking about..there's only two Celsius and Fahrenheit..83 degrees can't be converted into anything.Either its Celsius or Fahrenheit. Pay attention in class please!!

Why do the freezing points of graphite and carbon are same?

Graphite and carbon are both made up of carbon atoms arranged in a specific crystal structure. The freezing point of a substance is determined by the forces between the atoms or molecules. Both graphite and carbon atoms have strong covalent bonds, resulting in similar intermolecular forces, and therefore similar freezing points.

What is the solution's freezing point depression?

To solve freezing point depression problems, you need to know the following things:

-- the identity of the solute (the thing you are adding to the liquid)
-- the identity of the solvent (the liquid)
-- whether the solute is molecular or ionic, and if ionic, how many ions it forms
-- the amount of solute (in grams or moles)
-- the amount of solvent (in kilograms)
-- the value of Kf of the solvent (for water, it is -1.858 K·kg/mol (or -1.858 °C molal-1)
Then you use the following equation:
∆T = i * Kf * m

where ∆T is the change in the freezing point, "i" is the number of molecules or ions formed upon addition to the solvent, Kf is the freezing point depression constant, and "m" is the molality of the solution.
The Kf of water for a freezing point depression is known and is equal to -1.858 °C·kg/mol (or -1.858 °C molal-1)
The value of "i" has to do with what you add to the water. If you added sugar, a molecular compound the value of "i" is 1.0. If you add a ionic compound like NaCl, the value of "i" is 2.0 because for every 1 molecule of NaCl, you make 2 ions: one Na+ and one Cl- in water. For MgCl2, the value of "i" is thus 3.0 (for each MgCl2 you get one Mg2+ and two Cl- ions, so a total of 3 ions).
To find "m," the molality of a solution you need to know the number of moles of solute and the number of kilograms of solvent (m = moles/kg). If you are given the number of grams of solute, the number of moles is found from the mass and the molar mass of the solute.
grams of solute ÷ molar mass of solute = moles of solute
To find the molality, just divide the moles of solute by the kilograms of solvent moles of solute ÷ kilograms solvent = molality Note: If you are given the volume of the solvent instead of the mass, use the density of the solvent to convert -- the density of water is 1 kilogram per liter)
Liters of solvent * density of solvent = kilograms of solvent
Now just plug all the numbers into the equation at the top of the answer!

What Is twenty degrees Celsius cool or warm or hot or cold?

20 degrees in Australia is warm although it really depends on the persons opinion.

What is 72f in Celsius?

72ºF = 22.22ºC

You can use this equation to convert degrees Fahrenheit (F) to degrees Celsius (C): [°C] = ([°F] − 32) × 5⁄9

How much is 101.3 F in celsius?

101.3 degrees Fahrenheit is equal to approximately 38.5 degrees Celsius.
