The Physical Nature of Ice
On Monday afternoon we experimented to find out what temperature salt water (sea water) freezes. We measured the temperature of normal iced water and found it was close to 1 degree Celsius. But when we measure the temperature of the salt (sea) water, the temperature dropped as low as -3 degrees Celsius.
What does this mean?
It might mean that...
Sea water needs temperatures lower than zero degrees celsius for ice to form.
Below are some other questions we are inquiring into this week:
What are the three states of matter?
What is the difference between a solid, liquid and gas?
What happens to molecules of water as they freeze? (see the two links below)
Where does the energy go as water freezes?
