Melting Points

Meltingh points differ depending on the chemicals found in the solution that was frozen. Some melting points are above room temperature and some are below.

Objectives/Goals

The purpose of my experiment was to determine the melting rate of ice with different concentrations of salt and sugar solutions.

Methods/Materials

20 100 ml plastic cups
4 800mL plastic containers
220g salt NaCl(Ralph's Iodized Salt)
WhirlPool Gold Freezer
220g sugar (Pure Cane Sugar)
US Balance Professional Mini Scale US Magnum (500gx0.1g)
2,050mL tap water
100g balance calibration weight
5 funnels
Stopwatch
5 100 ml graduated cylinders
Masking tape

Results

The meting rates were:

Frozen Solutions Melting Rate of Ice (mL/min)
Control 0.20
1% Salt 0.25
1% Sugar 0.20
10% Salt 0.47
10% Sugar 0.26

Conclusions/Discussion

My conclusion is that salt lowers the freezing point of water more than sugar does which causes it to melt faster. 3rd party contributor

The science of heat energy can be very interesting to study.
