Which does ice melt slower plastic or wood?
Two identical pieces of ice, each placed on identically sized and shaped blocks of plastic and wood at the same temperature, will melt at a rate proportional to the thermal conductivity and the thermal mass of the object they are on. Generally, wood is a better thermal insulator than plastic. Short answer: wood.
Why do ice cubes melt faster than a block of ice with the same mass?
Ice cubes have a larger surface area compared to a block of ice with the same mass, allowing for more heat exchange with the surrounding environment. This increased surface area enables the ice cubes to absorb heat more quickly, causing them to melt faster than a block of ice.
Why a sheet of paper fall slower than a coin under gravity through air?
A sheet of paper falls slower than a coin in air due to differences in air resistance. The paper has a larger surface area compared to the coin, leading to more air resistance acting against its fall. This increased air resistance slows down the paper's fall compared to the coin.
Why does the sheet of paper fall slower than one that is crumpled into a ball?
A crumpled ball of paper has a smaller surface area compared to a flat sheet, leading to less air resistance and allowing it to fall faster. The crumpled ball also has more weight concentrated in a smaller area, increasing its momentum.
Will a flat sheet of paper accelerate at the same rate as a crumpled paper?
In a vacuum, both a flat sheet of paper and a crumpled paper would accelerate at the same rate due to gravity. However, air resistance may affect the acceleration of a crumpled paper more than a flat sheet due to differences in surface area and shape, causing the crumpled paper to fall slower.
How fast does it take for a cubic foot of ice to melt?
That depends on the shape of the ice, how cold it starts out and the condition of the surroundings. All other variables being the same, a block of ice starting at 0 °C will take less time to melt than one that starts at -100 °. Ice in an oven at 250 °C will melt faster than one sitting on the table in a 25 °C room. If the surroundings are maintained at - 50 °C, it will NEVER melt (although it might sublime). A block of ice 1 ft x 1 ft x ft will probably melt slower than one that is 6 inches x 6 inches x 4 feet, yet they are both "a cubic foot". Ice sitting on a plank of wood and surrounded by air at 50 °C will melt slower than the same block of ice dropped into liquid water at 50 °C. A block of ice will melt slower in the shade than if it is moved into the sunlight. Ice floating quietly in water will melt slower than if the water is swirling around it. Ice will melt slower in still air melts slower than ice with a wind blowing across it. A cubic foot of ice as one contiguous block will melt slower than if you take that same block and break it up in pieces. You have to be very specific about the conditions in order to make it possible to answer the question. For example: "A block of ice 1 ft x 1 ft x 1 ft initially at a uniform 0 °C floating in an unstirred vat of pure water which is maintained at a constant 45 °C"
How does a cooler melt ice slower than the sun?
foam insulation
Why does ice melt slower in sugar water than in vegetable oil?
you suck
Why does yogurt melt slower than ice cream and sherbet?
It has a thicker consistency. :)
Does a block of wood fall faster than a paperclip?
No because a paperclip weighs lees than a block of wood. A Block of wood falls SLOWER than a Paperclip.
Does a sphere shaped ice cube melt faster than a regular shaped ice cube?
A cylinder shaped ice cube will melt faster because it has a greater surface area than the rectangle-shaped ice cube has. Cubes of ice with less surface area will melt slower. Ice that has very low surface area has more ice concealed inside than it does on the outside. Therefore, ice cubes that have more surface area will melt faster... I hope this will help you.. :) ..
Does salt make snow melt slower?
No, salt actually makes snow melt faster by lowering its freezing point. When salt is sprinkled on snow or ice, it causes the ice to melt and form a saltwater solution, which has a lower freezing point than pure water. This allows the snow to melt at lower temperatures than it normally would.
Which does ice melt slower plastic or wood?
Two identical pieces of ice, each placed on identically sized and shaped blocks of plastic and wood at the same temperature, will melt at a rate proportional to the thermal conductivity and the thermal mass of the object they are on. Generally, wood is a better thermal insulator than plastic. Short answer: wood.
Does the shape of ice affect it's melting time?
Yes the shape of ice does affect its melting time. if you took a liter of water and froze it into a sheet 1/2 a cm thick, and another liter of water and shape it into a ball, then placed both pieces of ice outside to melt, the sheet would melt before the ball,this is because the sheet has more surface area than the ball so heat from the outside can get into it faster.
Why do ice cubes melt faster than a block of ice with the same mass?
Ice cubes have a larger surface area compared to a block of ice with the same mass, allowing for more heat exchange with the surrounding environment. This increased surface area enables the ice cubes to absorb heat more quickly, causing them to melt faster than a block of ice.
Why don't NFL teams use seven and eight footers to block kicks?
usually their slower than the smaller ones
Does temperature effect how a candle burns?
Yes. When a candle is in cold temperatures, it tends to melt much slower than a candle burning in room temperature.
