What is the point where pressure and temperature are just right for all three phases to exist at once on the phase diagram called?
This point is call the "triple point" and this is where all three lines meet together on the phase diagram.
In experiment preparation of copper (II) oxalate complex why the melting point of copper (II) oxalate not meet theory?
The observed melting point of copper (II) oxalate may not meet the theoretical value due to impurities in the sample or incomplete reaction during preparation. Factors such as water content, incomplete conversion of starting materials, or presence of unreacted starting materials can influence the melting point. It is essential to ensure purity of reagents, control reaction conditions, and thoroughly dry the product to accurately determine the melting point.
What are the two requirements that metals must meet before it can be used in a fuse?
Metals used in fuses must have a low melting point so they can easily melt when there is an overload. They also need to have high electrical conductivity to ensure efficient flow of current.
What is the the triple point on a phase diagram?
The triple point of a phase diagram is the location where the solid, liquid, and gas phases meet; it is the temperature and pressure at which a given substance can assume any of the 3 usual phases of matter.
Why is it more accurate to use the point of intersection of the two lines to find the mole ratio rather than the ratio associated with the trial with the greatest volume of precipitate?
There is a difference between where the two lines meet and where the greatest tempurature change is... think about it... the two lines do not meet where the greatest tempurature change is, the two lines meet where the greatest amount of heat is given off...
Where will the three scales of temperature meet?
The scales of temperature cannot all meet, as the Kelvin and Celsius scales have the same size degrees but different zero points. Absolute Zero is 0° Kelvin, and equal to -273.15 °C or -459.67 °F. Because the Celsius and Fahrenheit scales are offset by 32° at their starting points (freezing point of water), the two scales do have a common numerical point at -40° (minus 40 degrees). (see related question)
What is also equal to -40 degrees Fahrenheit?
-40 F = -40 C. -40 is the point where the two scales "meet".
Is -40 the same in Fahrenheit and Celsius?

What is the temperature in degree Fahrenheit and kelvin scales have same value?
The Kelvin scale begins at absolute zero (-459.67 °F), but because the Kelvin/Celsius degree intervals are larger, eventually the two scales will intersect. This occurs at 574.5875 K or 574.5875 °F, a temperature equal to 301.4375 °C . Calculation The formula T(K) = T(F) as expressed in C(Celsius). C + 273.15 = (9/5 C) +32 4/5 C = 241.15 C = 301.4375° (574.5875 K and 574.5875 °F )
How does celsius and Fahrenheit scales meet at -40?
It is a pure coincidence. Nothing special.
What number is numerically the same in degrees celsius and degrees Fahrenheit?
The point at which the Celsius and Fahrenheit scales meet is -40 degrees. -40 degrees Celsius is equal to -40 x 9 = -360 / 5 = -72 + 32 = -40 degrees Fahrenheit.
Where does one 40 always meet the other in a measurement?
The scales of degrees Celsius and Fahrenheit are equivalent at -40 degrees.
What is thevalue of -40 degree celsius?
-40 C is -40 F: it is the point where the scales meet.
-40 degrees Fahrenheit is how many degrees celsius?
-40 A lot of people like to use this as a trick question. -40 is where the two scales meet.
How much is -40F in degrees celsius?
Was that on purpose? Because it just so happens that -40 is where the two meet! -40 degrees Celsius = -40 degrees Fahrenheit. Was that on purpose? Because it just so happens that -40 is where the two meet! -40 degrees Celsius = -40 degrees Fahrenheit.
What temperature has same numerical value in kelvin and Celsius?
The Kelvin and Celsius scales of temperature cannot meet, as they have the same size degrees but different zero points. Absolute Zero is 0° Kelvin, and equal to -273.15 °C , so the temperatures in Kelvin will always be 273.15 degrees larger than the same temperatures expressed in Celsius.
How does Fahrenheit and celsius meet at -40?
Because the relation is 9/5 C + 32 = F; if you let F = C you find the point they are the same: -40F = -40C
