What determines the boiling point of a substance?
== == The amount of force that is holding the molecules of the substance together (intermolecular forces). A lot of things factor into this, including: * Hydrogen bonding * Ionic interactions * Hydrophobic interactions * Van der Waals forces * Permanent dipole-dipole interactions The stronger the intermolecular forces are (per molecule), the higher the boiling point will be, as it will require a greater amount of heat energy to overcome the intermolecular forces that hold molecules in a liquid state.
How do you get soft bitumen to set at room temperature?
Bitumen is not reactive in the sense that it sets. Furthermore, it's strongly temperature sensitive ie the apperance will depend on temperature. This is perhaps one of the main properties of bitumen, along with stickiness. If its fluid (or thick) n room temperature it will stay that way. There are slow processes, chemical and physical, that will affect properties but these are slow and long term. If you want it to set, lower the temperature or choose another quality of bitumen. There are bitumens that more or less brittle at room temperature.
What is -40.00 degrees celsius in Fahrenheit?
4000 °C is equal to 7232 °F
The conversion formula is Fahrenheit temperature = (9/5 x Celsius temperature)+ 32 4000C is 7,232F
What does 20 below zero degrees Fahrenheit equal in Celsius?
20 below zero degrees Fahrenheit is equal to approximately -28.9 degrees Celsius.
What is 22 degrees S and 43 degrees W?
Water. LOTS of water. These coordinates are in the Mozambique Channel.
However, if you're an exceptionally strong swimmer, you could probably make it to the island of Madagascar, which is only 14 miles to the east.
What temperature is the freezing temperature?
32 degrees Fahrenheit (or 0 degrees celsius) is the point of freezing.
How is the altitude affected by the temperature?
Temperature changes with an increase or decrease of altitude. This change is known as the "lapse rate" and it varies depending on the amount of moisture in the particular mass of air. The "dry adiabatic lapse rate" (for dry air masses) is a temperature decrease of about 3 degrees C per thousand feet of altitude, while the "wet adiabatic lapse rate" (for moist air masses) is a temperature decrease of about 1.66 degrees C per thousand feet of altitude.
For average conditions, a figure of 3.5 degrees F (2 degrees C) per 1000 feet is commonly used.
Why does the temperature reading have an OC inplace of the temperature?
The "OC" likely means that the temperature sensor is functioning but the reading is not detected or is out of range. This could be due to a faulty sensor, poor connection, or environmental factors affecting the sensor's ability to accurately measure temperature. It is advisable to troubleshoot the sensor or seek professional help to fix the issue.
Below 72 is to cool and above 76 is a little to warm for exercise areas. Most of us keep our homes at 78-80 degrees in the summer and about 74-77 in the winter.
The 65 degrees stated in a previuos answer would require many of us to wear a sweat shirt over our normal Only tee shirt.
61 degreesThis temperature allows for the best workout. Otherwise it gets so warm muscles become fatigued and fail. I personally prefer 60 degrees and never heat my home over 70.What is the temperature drop from 3 degrees Celsius to -7 degrees Celsius?
The temperature drop from 3 degrees Celsius to -7 degrees Celsius is 10 degrees.
Why is the temperature range of a clinical thermometer 35 degree Celsius to 42 degree Celsius?
Because if a person's temperature went outside that range, they would be in very serious medical danger. At those extremes, knowing the exact temperature would matter far less than urgent action to bring it back into normal range.
How does the size of a Fahrenheit degree compare to the size of a kelvin degree?
A Fahrenheit degree is smaller than a Kelvin degree. In the Fahrenheit scale, one degree is equal to 1/180th of the interval between the freezing point and boiling point of water, while in the Kelvin scale, one degree is equal to the same size increment as one Celsius degree, but starting from absolute zero.
How can a temperature in degrees Fahrenheit be below freezing if it is above 0 degrees F?
On the Fahrenheit scale, the freezing temperature of water is 32 degrees at atmospheric pressure.
On the same scale, the freezing temperature of gold is 1,948 degrees at atmospheric pressure.
Does the celsius sign go before or after the C?
The Celsius sign is the C; the little circley thing at the top is the degree sign and goes before the C
delta T x specific heat x mass Delta T = change in temperature specific heat of water = 4.1813 J/gC Mass= 45.0g 48C-14C=34C 34 C x 4.1813 J/gC=142.1462 J/g 142.1462 J/g x 45g = 6397.389 J restricting us to three significant digits = 6.40 x 10^3 J

From the evidence of developing countries all over the world, a number of social problems are generated. As a result, an unsteady development has become a rising concern in today's contemporary society, and there is no doubt that companies and countries are responsible for this issue.
The problem is derived from an increasing sense of inequality between the the city and countryside. People from the countryside will try to move to the cities to get more employment opportunities and better access to the facilities available there. Therefore, this increase in the urban population puts great pressure on housing and services.
This can be solved with improving the standards of living and the facilities available in the countryside. Perhaps incentives can be offered to factories and companies to relocate. In order for these to built road and rail network to make relocation possible as well as to require doctors and teachers to spend part of their professional lives in rural areas.
In conclusion, the sense of inequality is crucial issue in a country's economic development, therefore, governments and companies should take practive steps to make sure that people understand the importance of balanced development for reducing these problems.
Why are the freezing melting and boiling points lower on high altitude?
Heat is only energy. In areas of low pressure, such as high altitudes, "heat" particles, which are charged electrons, escape more quickly. As more "heat" (electrons) escapes more quickly, things freeze more quickly.
As far as I know melting and boiling points are higher, not lower in high altitudes.
What happens to sugar when put in water at freezing and boiling point?
Sugar lowers the freezing point of a liquid by a process called "freezing point depression". The same idea is used when salt is sprinkled on icy roads to melt the ice. Sugar only works half as well as salt however.
How many is 114 degrees Fahrenheit in celsius?
114 degrees Fahrenheit is equal to approximately 45.56 degrees Celsius.
How many Fahrenheit degrees are equal to 180 degrees C elsius?
180 degrees Celsius is equal to 356 degrees Fahrenheit.
What is 750 Fahrenheit converted in Kelvin?
750°F is equivalent to 944.82 Kelvin. To convert Fahrenheit to Kelvin, you can use the formula: K = (F + 459.67) x 5/9.
