What is the difference between freezing and boiling points on a Fahrenheit scale?
The difference between the freezing and boiling points vary from substance to substance.
Does pure water or salt water have higher freezing points?
normal water
Which of these values is most responsible for changing the boiling and freezing points of a solvent?
The concentration of solute in the solvent is most responsible for changing the boiling and freezing points. When a solute is added to a solvent, it disrupts the normal intermolecular forces between solvent molecules, which results in a change in the boiling and freezing points of the solvent.
What are the basic units in Celsius?
The basic unit is the "degree Celsius". It's 1/100 (0.01) of the temperature difference between the freezing and boiling points of water.
What is the different between 67 Celsius and -55 Celsius?
The 67 degree centigrade indicates that it is 67 points above the freezing point of water and it shows body is hotter.-55 0C shows that it is 55 points below freezing point of water at normal conditions and the body is colder.

Why is the number 32 in the conversion formula for temperature?
When Fahrenheit devised his scale, he defined 0oF to be the freezing point of brine, 32oF to be the freezing point of water and 96oF to be normal body temperature. Water then boiled at about 212oF. The scale was later redefined to make water boil at exactly 212oF whilst leaving water freezing at 32oF (making the freezing point of brine slightly lower and normal body temperature slightly higher). The 32 is needed when converting between Celsius and Fahrenheit as Celsius defines freezing point of water at 0oC which equals 32oF on the Fahrenheit scale. The 180oF difference between freezing and boiling points of water is scaled to match the 100oC difference. Thus the conversion is: F = 180/100 C + 32 = 9/5 C + 32
Are freezing and melting points characteristic properties?
Yes, freezing and melting points are characteristic properties of a substance. They are specific temperatures at which a substance changes its state from solid to liquid (melting) or from liquid to solid (freezing) under normal atmospheric pressure.
Are boiling points and freezing points checimal changes?
No, boiling points and freezing points are not chemical changes. They are physical properties of a substance related to its phase transition between solid, liquid, and gas states. Chemical changes involve the formation of new substances with different chemical properties.
What is the boiling and freezing points of juice?
It's freezing point is between 0 to (-1) *c& boiling point is between 103 to 105*c
How can you rank aqueous solutions based on their freezing points?
Aqueous solutions can be ranked based on their freezing points by comparing the concentration of solutes in the solution. The more solutes present, the lower the freezing point of the solution. This is because the solutes disrupt the formation of ice crystals, preventing the solution from freezing at the normal temperature.
Finding the normal freezing and boiling points of 21.2 g NaCl in 135mL of water?
The normal freezing point depression constant of water is 1.86°C/m. The normal boiling point elevation constant of water is 0.512°C/m. First, calculate the molality of the NaCl solution. Then use these constants to find the new freezing and boiling points of the solution.
