Can you melt people?
You as a human cannot melt from heat. The worse thing is that you might get burnt. EXP: An ice cube will melt in heat...I don't think you're an ice cube!! :)
What happens when heat meets a solid?
If the solid is made of ice, then it will melt. But if you have enough heat, you can make the solid item melt.
How many joules of heat are required to melt 40 kg of ice at 0 dg C?
In order to answer this question, you need the enthalpy of fusion of ice, which is 333.55 J/g (Joules/gram). The enthalpy of fusion is the amount of heat that must be absorbed or lost in order to change physical state. The number of Joules required to melt the ice = enthalpy of fusion of ice x mass of ice. 1 kg = 1000g 40kg x (1000g/1kg) = 40,000g Joules needed to melt the ice = 333.55 J/g x 40000 g = 13342000 J or 1.3342 x 107 J
Does the size of ice affect its melting time?
Because the larger the piece of ice is, the longer it will take for heat to melt it. I smaller piece of ice has fewer layers that heat needs to penetrate to melt it compare to a larger piece of ice.
How much heat is required to melt 5 kg of ice?
it depends how cold the ice is
How is the amount of heat needed to melt ice related to the amount of heat needed to freeze the same amount of water?
The two amounts are the same but have the opposite sign (positive vs negative).
When you melt ice what heat is it called?
When melting ice, you are moving from a solid to a liquid. Any state change from a solid to a liquid is called the heat of fusion. In other words, whenever melting takes place, the amount of energy needed is referred to as the heat of fusion.
What temperature does ice melt fastest?
Cold water will not melt the ice cube in record time, but hot water will, but salt water will also melt it fast, but if you add both together the ice cube will melt alot fast. Deceasing time alot.
How do you solve a problem finding the heat that is required to melt ice?
You would start by looking up the specific heat of fusion for ice. Then you multiply that by the amount of ice you're trying to melt (you may have to do some unit conversion to get your specific heat and ice mass in compatible units). That will give you the amount of heat required, and again you may need to do a unit conversion to get it in the units you want.
The heat needed to melt one gram of a solid at its melting point is what?
The heat needed to melt one gram of a solid at its melting point depends on the heat of fusion value of the solid. To melt one gram of ice, for example, would require 334 J.
What has to happen to melt ice?
the ice melt when there s some heat move into it.
Why is energy needed to melt ice?
Heat is hotness and when ice has hotness in the surroundings, it will changes its temperature to fit in with the room temperatute, therefore ice will change its state
Why energy is needed to melt ice and how this is explained by the structures of ice and water?
Because the ice structure is made up of frozen water molecules, which are blown by fairies creating heat which makes the ice melt like butter in a dragons mouth.
What is added to ice to make it melt and how does this affect the molecules in the ice?
Heat is added to ice to make it melt.
How does snow and ice melt?
Heat.
Does the shape of an ice cube affect how long it takes the ice cube to melt?
Yes, absolutely. Heat transfer from the surrounding environment into the ice cube causes it to melt. The greater the rate of heat transfer INTO to ice cube, the faster it will melt. The greater the surface area of the ice cube, in relation to it size, the faster the melting will occur. The ideal shape for the least heat transfer [and this is true for cold or hot objects] is a SPHERE. A sphere has the minimum surface area for the mass of the object. Any shape other than a sphere has more surface area for the mass, an will melt faster. The thinner more spreak out ice will melt faster melting consumes enerhy inthe form of heat. The amount of energy needed is the proportional of the ice water. The heat applied to it can be radiation or matter. Johnson Kevin, Ohio
What the best way melt ice without use of heat?
There is no way to melt ice without heat. If you see ice melting, you know that it is absorbing heat. There is no other way for this to happen.
