I would take a small quantity of cold water, and an equal quantity of hot water in an identical
container, plunge both containers into the freezer, open the freezer briefly and touch the surface
of each sample once every 15 minutes until one of them is frozen solid, and then try to remember
which container was which.
What else can I help you with?
What would change for which freezes faster hot or cold water?
Hot Water
What freezes faster in less than an hour salt or tap water?
Tap water would freeze faster but salt water would allow the waters freezing point to be lowered.
What happens if water freezes in a crack of a rock?
The crack would expand because the water in the rock, as it freezes, expands.
A hypothesis for which freezes the fastest cold or hot water?
A hypothesis for which freezes the fastest between cold and hot water could be that hot water freezes faster than cold water. This phenomenon, known as the Mpemba effect, has been observed under specific conditions where hot water cools faster than cold water due to factors such as evaporation and convection currents. This hypothesis would need to be tested through controlled experiments to draw a conclusion.
Does water freeze faster in plastic or metal?
Water freezes faster in metal compared to plastic due to the higher thermal conductivity of metal. This means that heat is transferred more efficiently from the water to the metal, allowing it to cool down more rapidly. In contrast, plastic has lower thermal conductivity, leading to slower heat transfer and a longer freezing time for the water.
A temp of 273 k is the temp at which water?
water can't actually reach that temperature because temperature is actually a measurement of how fast the particles in an object are moving. once they reach boiling point (100) the water particles cant go any faster and so they evaporate and change into a gas. if you left the water on the heat then it would eventually all evaporate and there would be nothing left in the container. if you put a lid on the container it would explode because the particle's would have no where to escape.
Does boiled water really freezes faster than cold water?
Check out this website for your answer. It would take too long for me to type it all. http://math.ucr.edu/home/baez/physics/General/hot_water.html
Which freezes first hot cold or salt water?
Salt water freezes before plain water because the presence of salt lowers the freezing point of the water. Cold water will freeze faster than hot water because the molecules in the cold water have less kinetic energy and are more likely to form solid ice structures.
What freezes faster sugar water or salt water or water?
Assuming you had equal amounts of each, the pure water would freeze first...Adding sugar or salt to water lowers its freezing point, meaning that more energy would be required to be removed from salt water and sugar water to freeze it
Which would freeze faster salt water or tap water with examples?
Tap water would freeze faster. That's the reason road crews apply salt to streets in the winter time. The salt water keeps the roads in a liquid state down to zero degrees Fahrenheit. Tap water is more like freezing rain. It freezes at 32 degrees Fahrenheit.
If water was boiled an a saucepan would water be evaportated faster or slower than water that is not heated?
it would be faster
What is the difference of freezing points between sea water and normal water?
Not as much as I would of thought. Normal water freezes at 0 degrees and lower. Salt water freezes at about -2digrees,(-1.93 to be exact)
