Experiment on the melting and freezing point of stearic acid?
To determine the melting point of stearic acid, heat the substance gradually in a controlled manner until it completely melts and note the temperature. To find the freezing point, allow the liquid stearic acid to cool slowly until it solidifies, recording the temperature when this occurs. Compare the two recorded temperatures to calculate the melting and freezing points of stearic acid accurately.
Compare boiling and freezing point?
for example ....water:freezing point: liquid freezes to ice boiling point: liquid boils and turns into vapor melting point: ice melts to liquid
Conclusion of determination of melting point?
Melting point of a solid involves the temperature changing from solid to liquid. Solid and liquid exist in in-equilibrium. The liquid to solid process is known as freezing or crystallisation.The principle of observing the disappearance rather than the forming of ice is known as the melting point.Source(s):Wikipedia
PH method to determine a pH of a substance?
To determine the pH of a substance using the pH method, you will need a pH meter or pH strips. For a pH meter, simply immerse the electrode into the substance and wait for the reading to stabilize. For pH strips, dip the strip into the substance and compare the color change to the provided chart to determine the pH value.
How does vapor pressure of water at 50 oC compare with its vapor pressure at 50 oC?
The saturated vapor pressure of water at 50 oC is 123,39 mm Hg.
How do the melting point and the freezing point of a substance compare?
Both indicate the temperature at which the solid and liquid states of a substance are in equilibrium.

How do the freezing point and the melting point of water compare?
They are identical.
How does the freezing temperature of water compare to its melting temperature?
The freezing temperature of water is the same as its melting temperature for pure water at sea level, which is 0 degrees Celsius (32 degrees Fahrenheit). This is the temperature at which water transitions from a liquid to a solid (freezing) or from a solid to a liquid (melting).
How does a thermometer help when comparing the energies of particles?
A thermometer measures the amount of thermal energy a material has. This thermal energy is related to the vibrational and rotational energy the particles in the material have. By using the thermometer to measure the temperature of a material you are, in effect, measuring the amount of energy the particles of that material have.
Why is temperature the measure of average energy of motion of all the particles within a substance?
Temperature is the measure of average energy of motion of particles within a substance because temperature reflects the amount of kinetic energy present in the particles. As particles move faster, they have higher kinetic energy. By measuring the average kinetic energy of particles, temperature provides a standardized way to compare the thermal energy of different substances.
What will happen when you compare the freezing point and melting point of water?
By definition, they are the same!
How does the water temperature compare to the air temperature?
The water temperature can be different from the air temperature.
Why does the freezing point affect the freezing of salt water?
It does not, but salt affects the freezing point. All solids are frozen. Each has a different freezing point. Ice is just the freezing point of water. But your computer keys are frozen too. Different substances freeze differently. But for your purposes, compare water to salt water. The salt in the water causes there to be more things in the water that disrupt the tight hydrogen bonds.Since freezing is tighter H-bonds, salt lowers the freezing temperature because it is harder to freeze it now since there is salt in it.
How do you compare Saturn's temperature to earth's temperature?
Because of atmosphere
How do you determine the substance given the mass?
To determine the substance given the mass, you would need to compare the mass to the known density of various substances. By dividing the mass by the volume (which can be calculated from the dimensions of the object), you can determine the density of the substance. Then, you can compare this density to known values to identify the substance.
