Snow Day
Some researchers were given the task of determining which factors affect downhill snow sledding speed at a public park. On Day 1, a sledder rode three different types of sleds down a snow-covered hill from starting heights of 30, 60, and 90 meters (m). The combined mass of the sledder and each sled was 80 kilograms (kg). The sledder wore a helmet for safety. On day 2, the sledder and researchers returned to the same hill to continue collecting data. The snow had melted slightly and then had frozen again overnight. The snow-covered area was more like a solid sheet of ice than the fresh snow from the day before. On day 2, the timing of sled three was not completed because heavy rain started. The table below shows the data collected on sled speed in relation to the different starting heights on the hill. Each sled speed indicates the average speed at which the sled traveled from the starting height on the hill to the bottom of the hill.

A group of students wanted to investigate whether the melting snow during the sledding day was a physical or chemical change. They followed these steps for the investigation.
Collect a large clump of snow and place half of it into a container in a freezer.
Place the other half of the snow into a container on a tabletop.
After the snow on the tabletop melts, place 200 grams (g) of it into a beaker.
Place 200 g of snow from the freezer into another identical beaker.
Measure the boiling point of the contents of each beaker with a thermometer.
They recorded their measurements in the data table below.


The students determined the __________ of both the snow and liquid water.
The snow went through a __________ as it became liquid water.
