cos its frozen water
because the ice can cool you down and its frozen and frozen things are cool and because ice has the ability to absorb more heat energy than water in scientific terms ice has a large latent heat of fusion which makes it a better cooling agent than water
Cooling things!
Their molecules vibrate less vigorously.
Applications of dry ice (solid carbon dioxide): - cooling of foods - material for fog machines in theaters - dermatology treatments - degassing of containers from hazardous gases - blast cleaning - bombs - etc.
An ice cube melting into water and then refreezing back into an ice cube is an example of reversible change. Another example is heating and cooling certain metals, such as a paperclip, which can be straightened when heated and then reshaped when cooled.
If you do not mix whislt cooling/freezing the finished ice cream will not be smooth and 'creamy' because large ice crystals will have formed in the mix.
because they're ice..
It is the cooling of the injury which does it good. It doesn't matter what you use to achieve that.
Yes if that material is softer than the ice it will break
Dry ice is made by cooling carbon dioxide to its solid state.
Ice is natural material present in frozen lakes and glaciers. In the past it was a resource and essentially mined during the winter and stored in ice houses to be sold as the coolant in ice boxes (a primitive refrigerator.) At the present time ice is manufactured by refrigeration systems making it a manufactured product, not a resource. Modern refrigerators do not rely on ice for cooling. the systems generate the cold without the ice.
You can grind glass or plastic. For fun you can make a good lens out of ice.
