Why does the presence of double bonds decrease the melting point?

most likely because the forces keeping the atoms bonded gets weaker with each added bond and therefore it is easier for heat to separate the atoms. most likely because the forces keeping the atoms bonded gets weaker with each added bond and therefore it is easier for heat to separate the atoms.

--> Yes, but the reason is because the introduction of a double bond results in bends in the molecule which makes it harder to 'pack' these molecules into a low energy crystalline, solid state. Therefore, they more easily break out of the solid state and melt into liquids (= bonds generally end up in the 'cis' configuration). Note that although they have lower melting points than their respective counterparts, they have higher boiling points due to the polarity associated with the double bond.

What is -350 degrees Fahrenheit in Celsius?

350 deg C = 662 deg F.
It's easy to convert from Celsius to Fahrenheit by yourself. Tf = (9/5)*Tc+32, where Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit. 350 C is 662 F.

If the boiling point of a certain amount of a liquid is 150 degrees then what is the boiling point of twice that amount of the liquid?

The boiling point of twice the amount of liquid will remain 150 degrees. The boiling point of a substance is determined by the chemical properties of the substance itself, rather than the quantity of the substance.

How do you convert Kelvins to degrees Celsius?

Use this equation to convert Celsius/Centigrade to degrees Kelvin: [K] = [°C] + 273.15

How do you subtract negative 18 degree celsius from 86 degree Fahrenheit?

86 deg F = 30 deg C

So the temperature has changed from -18 deg C to 30 deg C, an increase of 48 deg.

Conversely,

-18 deg C = -0.4 deg F

So the temperature has changed from -0.4 deg F to 86 deg F, an increase of 86.4 deg.

What is the room temperature in Fahrenheit?

Room temperature is typically around 68-72 degrees Fahrenheit.

Does Alcohol and mercury thermometer measure the same temperature at 60 degrees?

Yes. If they're good quality and accurately calibrated, they do. If two thermometers in

the same place under the same conditions don't read the same number, then at least

one of them is wrong.

Where in the world are temperatures rising?

Temperatures are rising globally due to climate change, but some regions experiencing more pronounced warming include the Arctic, parts of Africa, the Middle East, and Southeast Asia. These areas are seeing increased frequency of heatwaves, melting ice caps, and other extreme weather events.

180 degrees C equals what in degrees F?

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 = 180 * 9 / 5 + 32 = 356 °F
180 degrees Celsius is 356 degrees Fahrenheit.
What is 180 degrees Celsius in Fahrenheit?

f = 9/5 c + 32 = 356 f

What is 240 kelvin in Celsius?

The answer is -33.15 C(approx.). The Kelvin scale starts at absolute zero and is used in scientific laboratories. Celsius is for general use and set 0 and 100 as melting and boiling point of water respectively. To convert from K to C, subtract 273.15 from K.

Which countries use degrees Celsius?

Fahrenheit remains the official scale for the following countries and territories: the Bahamas,Belize, the Cayman Islands,Palau, and the United States and its associated territories. Everyone else uses Celsius.

What is 45 degrees Celsius in Fahrenheit?

Conversion: 45 °C → 45 × 9/5 + 32 °F = 113 °F
113 F

What happens to water at 25 degrees celsius?

Nothing. It is a liquid.

Water freezes at 0 degrees Celsius, and boils at 100 degrees Celsius.

What is the melting point of iron in degrees celsius?

Iron melts at 1536 °C or 2797 °F (1811 K). It boils at 2862 °C or 5182 °F (3134 K).

How many calories would it take to heat up Lake Michigan by 1 degree Celsius?

To calculate the calories required to heat up Lake Michigan by 1 degree Celsius, you would need to know the specific heat capacity of water (4.186 J/g°C) and the mass of water in Lake Michigan. The formula to calculate the energy required is: Energy = mass of water x specific heat capacity of water x change in temperature. This would give you the calories needed to heat up Lake Michigan by 1 degree Celsius.

Fahrenheit 2 X Celsius 30?

(F-32)/1.8=C, where F=degrees Fahrenheit and C=degrees Celsius.

Is it possible to have snow that sticks to the ground when it is above 32 degrees Fahrenheit?

Only for a very short time. Recorded weather readings are taken at a height of 5 feet above the ground. If the ground has been frozen, the air temperature at ground level will be a few degrees cooler than the official temperature. It is not unusual for snow to remain for days or even weeks in shaded areas when the air temperature is well above freezing during the afternoons but near or below freezing at night.

What does temperature measure?

Temperature measures how fast molecules are moving or in scientific terms it measures the AVERAGE KINETIC ENERGY in a system. Temperature measures how fast molecules are moving. :):)

What is -12 degrees Fahrenheit in Celsius?

-12 degrees Fahrenheit is approximately -24 degrees Celsius. To convert Fahrenheit to Celsius, you can use the formula: (°F - 32) * 5/9.

What is the normal freezing point of water in Kelvin?

273.15K is the melting point of water in kelvin

That's not correct; water boils at 100 degrees Celsius, to go from C to K, you add 273 to the Celsius temperature...

100+273 = 373 degrees K

How do you convert Celsius into Fahrenheit?

Multiply degree Celsius reading by 9, divide answer by 5, then add 32 This calculates degrees Fahrenheit °F if you know degrees Celsius °C: °F = (°C × 9 / 5) + 32 or °F = (°C × 1.8) + 32 Here is a nice temperature converter. Try it yourself. Scroll down to related links and look at "Conversion temperature units". Use this equation to convert degrees Celsius/Centigrade (ºC) to degrees Fahrenheit (ºF): (ºC x 1.8) + 32 =ºF

What is the Fahrenheit equivalent of 100 degrees centigrade?

100 degrees Celsius is the boiling temperature of water at standard pressure. The Fahrenheit equivalent would be 212 degrees F.

How many calories are required to convert 17g of ice at 0 degrees Celsius to liquid water at 32 degrees Celsius?

The simple beginning is that the definition of a calorie is "the energy required to raise the temperature of 1g of water 1°C." Therefore, the energy required to raise 17g of water 32°C: 17*32=544 cal. However, the question asked about ice. There is an extra bit of energy required for the change of physical state. The energy required to convert 1 gram of ice at 0°C to liquid water at 0°C is called the "latent heat" and is equal to about 80 cal. To convert 17g of ice, we multiply this together: 17g * 80cal/g = 1360 cal. So, we add this energy required for the change of state to the energy required to raise the listed quantity to the required temperature and we get 544 cal + 1360 cal = 1904 cal, assuming no heat is lost to the environment.

I hope this clarifies some things.
