What is suface tension?
The amount of energy needed to break the surface of a liquid.
Why is the temperature needed to freeze ocean water lower than the temperature needed to freeze the surface of a fresh lake?
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.
Why is the temperature needed to freeze the ocean water lower than the temperature needed to freeze the surface of a freshwater lake?
Dissolved salts in water contribute to a decrease of the freezing point.
Why is the temperature needed to freeze ocean water lower than the temperature needed to freeze a surface of a fresh water lake?
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.
Why is the temperature to freeze the surface of ocean water lower than the temperature needed to freeze the surface of water like Lake Superior?
The ocean water has a high amount of dissolved salts.
Why is the temperature needed to freeze ocean water lower than the temeperature needed to freeze the surface of a freshwater lake?
cos it contains salt :)
Why is the temperature needed to freeze ocean water lower than the temperature to freeze the surface of a fresh water lake?
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.
What will affect the ammount of solid needed to make a saturated solution?
the amount of solid there is and the temperature might also affect the amount of a solid that dissolves.
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.
Does the shape of a 1-liter tank affect the amount of time needed to cool it?
Yes, since the shape will affect the surface to volume (1 litre) ratio.
What factors effect friction?
Factors that affect friction include the nature of the surfaces in contact, the force pressing the surfaces together, surface roughness, and the presence of lubricants or contaminants. Friction also depends on the velocity of the objects in contact and the temperature of the surfaces.
How does the surface affect the force needed to drag a box of toys?
The rougher the surface, the more force is needed to drag a box of toys across it due to increased friction between the box and the surface. A smoother surface will result in less friction, requiring less force to move the box.
