The compound with the chemical formula CF4, carbon tetrafluoride, is nonpolar. Unlike other molecules that are nonpolar because they feature only nonpolar bonds, CF4 has this property despite having four polar bonds in its structure.
Continue ReadingThe lack of polarity of CF4 is caused by the geometry of its molecule, which is tetrahedral, or pyramid-shaped. Although the bonds themselves are polar, the four bonds between carbon and fluorine cancel out one another, generating a nonpolar molecule. CH4, or methane, is the same as CF4 in this respect, as are many other molecules made of four halogens surrounding a carbon or silicon atom.
Learn more about ThermodynamicsThe formula for calculating thermal conductivity is heat multiplied by the distance divided by the product of surface area times the temperature gradient. NDT Resource Center explains that thermal conductivity is the property of a material to conduct heat. Increased thermal conductivity means a higher rate of heat transfer.
Full Answer >To convert any temperature in Fahrenheit to Celsius, follow this formula: subtract 32, multiply by 5 and divide by 9. When you input 105 degrees Fahrenheit into this formula, the result is 40.56 degrees Celsius. It takes just a couple of minutes to complete the math problem.
Full Answer >The formula to calculate force is: force = mass x acceleration, or F = m x a, where force and acceleration have both magnitude and direction. A force is an interaction that acts upon the state of motion of an object.
Full Answer >The formula for heat transfer, Q=Cm?t, provides the amount of heat transferred (Q) by plugging in the relevant numbers. "C" stands for the specific heat value, "m" is for the mass of the object and "?t" refers to the temperature change in Kelvin.
