Why does cement crack after salt is put on it when it is frozen?
When cement is frozen it shrinks. the salt adds heat and it expands. The cement is not used to the change and it expands to much and it cracks. just like when paper rips. =============================== I have a different mechanism to propose: -- Salt on the surface of the frozen rock melts the fine layer of ice on the rock, just as it does when salt is used on the roads or sidewalks. -- The liquid water seeps into microscopic cracks in the cement. -- When the water re-freezes, it expands, cracking the cement.
Frozen salt water melt faster then frozen fresh water?
Salt lowers the melting or freezing point of water. The effect is termed 'freezing point depression'. Therefore frozen salt water melts faster and remain melted for long.
Are the locations of earthquake scattered randomly over the surface of the earth or are they concentrated in definite areas?
scattered randomly because it depends on the tchtonic plates
What is the name of excretes salt from its surface?
The process of excreting salt from the surface of the body is called salt excretion.
How is sea ice different to freshwater ice?
Sea ice contains frozen minerals, such as salt, that is not frozen into freshwater ice.
Why salt scattered on frozen surface?
Salt is scattered on a frozen surface to melt the ice.
Why salt is scattered on a frozen surface or iced surface of a skating rink?
They are scattered on the iced surface to stop the ice from melting and slow down the melting.
Why salt is scattered on ice surface?
They are scattered on the ice surface to stop the ice from melting and slows down the melting process
Why is the temperature needed to freeze ocean water lower than the temperature needed to freeze the surface of a freshwater lake?
because the ocean has salt in it rather than freshwater lake Because fresh water on the surface of a lake is frozen. Under similar conditions, salt water is not frozen.
Why is the temperature needed to freeze ocean water lower than the temperature need to freeze the surface of a freshwater lake?
because the ocean has salt in it rather than freshwater lake Because fresh water on the surface of a lake is frozen. Under similar conditions, salt water is not frozen.
Does salt separate when frozen?
no

What do fish do when the water surface is frozen?
If the water surface is frozen, fish continue to swim.
Why you sprinkle the salt on the frozen roads?
Salt melts ice.
What is a word meaning scattered widely?
Strewn means scattered untidily across a surface or area.
If sea water is frozen will the salt go away?
no, the salt wont go away it will just be inside the frozen water i don't think salt freezes though.
How can you effectively melt ice using salt?
To effectively melt ice using salt, you can spread salt on the icy surface. The salt lowers the freezing point of water, causing the ice to melt. This process works because the salt disrupts the ice's ability to stay frozen, making it easier to remove.
