What are the boiling point and the freezing points of water in Fahrenheit and Celsius?
At STP ie (1 Atm or 101.325 kPa, 760mm Hg) The boiling point of pure water is 212 °F or 100 °C The freezing point of pure water is 32 °F or 0 °C
What would the final freezing point of water be if 3 mole of sugar were added to 1 kg of water?
The CHANGE in freezing point can be determined from ∆T = imK where ∆T is the change in freezing point, i is van't Hoff factor (1 for sugar, a non electrolyte), m is molality (moles solute/kg solvent), and K is the freezing point constant for water (1.86). Thus ∆T = (1)(3)(1.86) = 5.58ºC. So, the FINAL freezing point will be -5.58ºC
The solution has a freezing point of -2.79 . The freezing point depression constant for water is 1.86 K m-1. What is the nitrate concentration in the solution?
The solution has a freezing point of 2.79 and this is the frezzing point of mercury
How much would the freezing point of water decrease if 4 mole of Na Cl were added to 1 kg of water?
The freezing point decrease is -14,8 oC.
Using the phase diagram for H2O, which of the following correctly describes water at 0°C and 1 atm?
At the melting point (Explanation) if you look at the phase diagram and look at the point where the water is 0 degrees C and 1 atm, they meet right on the line. This is the line that shows the melting point of this substance. Therefore, since the point is on the line, water at 0 degrees C and 1 atm is at the melting point.
What is the freezing point and boiling point of water when the pressure of the water is 1 atm?
These temperatures are 0 0C and 100 0C.
What are the boiling point and the freezing points of water in Fahrenheit and Celsius?

What is the pressure (in ATM) at the normal boiling point of water?
1 atm

What is the melting point of pure matter distilled water?
The melting point of ultrapure water is 0 0C at 1 atm.
What temperature does liquid water change into ice in degrees Kelvin?
273.15 kelvin because 1 ATM is reffering to the normal atmospheric pressure so it is the normal freezing point converted to kelvin Rob

How much would the freezing point of water decrease if 4 mole of Na Cl were added to 1 kg of water?
The freezing point decrease is -14,8 oC.
How much would the freezing point of water decrease if 4 moles of Na-Cl were added to 1 Kg of water?
The freezing point decrease is -14,8 oC.
What affects freezing point?
The factors that affect the freezing point of water are 1. pressure : the pressure on the liquid may alter the freezing point. 2. impurities : the impurities in water such as salt, sugar etc also alters the freezing point.
What is the pressure in ATM at the normal boiling point of water?
At the standard atmospheric pressure of 101325 Pa water boils exact at 100 degrees Celsius.
What does each degree on the celsius scale represent?
The Celsius scale was created so that 0 was defined as water's freezing point and that 100 was defined as water's boiling point (at 1 ATM of preasure). /\ (that means "delta" or "change of/in") /\ 1C = /\1.8F So if the temp increases by 1 degree celsius, then that is a 1.8 degree increase Fahrenheit .
