What else can I help you with?
What mineral helps keep schools open during snowy and icy weather by melting ice?
The mineral that helps keep schools open during snowy and icy weather by melting ice is sodium chloride, commonly known as rock salt. When spread on roads and sidewalks, it lowers the freezing point of water, effectively melting ice and snow to improve safety and accessibility. This is particularly important for maintaining safe conditions for school transportation and access during winter storms.
Why do we put salt in the sidewalk?
Salt is often put on the sidewalk during or after it snows. This is because salt lowers the freezing point of ice. This is often just enough to melt snow at subfreezing temperatures.
What is an icy piece of rock fragment moving through space?
That, my friend would be a Comet.
How does it help people drive when workers spread sand over icy roads?
Spreading sand over icy roads provides traction for vehicles by increasing friction between the tires and the road surface. This helps to reduce the likelihood of slipping and skidding, improving overall safety for drivers.
Does a chemical change happen in spreading salt on icy roads?
Yes, a chemical change occurs when salt is spread on icy roads. The salt dissolves in the moisture on the road and lowers the freezing point of the water, causing it to turn into a saltwater solution. This process facilitates the melting of the ice and helps to improve road safety.
What do you think would happen if you spread regular table salt (sodium chloride) on an icy sidewalk?
it will melt
What force makes it less likely for a person to slip on a dry sidewalk as opposes to an icy sidewalk?
The dry sidewalk has more friction compared to the ice on the icy sidewalk
What is icey?
It is spelled "icy", as in "I slipped on the icy sidewalk."
What force makes it less likely for a person to slip on a dry sidewalk opposed to an icy sidewalk?
Friction
What force makes it less likely for a person to slip on a dry sidewalk as opposed to an icy sidewalk?
Friction is the force that makes it less likely for a person to slip on a dry sidewalk compared to an icy sidewalk. Dry surfaces provide more friction between the shoe and the ground, allowing for better grip and stability. Ice reduces this friction, making it easier for a person's foot to slip.
The force that keeps you rom sliding on an icy sidewalk is?
Friction is the force that keeps you from sliding on an icy sidewalk. When you walk, the friction between the soles of your shoes and the ice surface prevents you from slipping.
A sentence for the word slid?
We slid down the slope.
What is a liability hazard?
A liability hazard is any type of hazardous situation that can cause a lawsuit. One example of a liability hazard would be an icy sidewalk outside your home.
How could you increase the friction on an iced covered sidewalk or icy road?
Pour sand over the ice.
Which has the lowest albedo a pond an icy lke a blacktop hightway or a a white sidewalk?
A blacktop highway
What is spread on icy sidewalks to lower the freezing point of the water?
Salt
How can adding sand on a icy sidewalk prevent people from slipping and falling?
Sand is dry and rough so it causes friction Hope this helps ! :)
