Why the time needed to vaporize a sample is greater than the time needed to melt a sample?

The amount of time depends on the latent heat of vaporisation and the latent heat of melting.

Would Ice cubes with the same volume but different surface areas melt at the same soeed?
No, the greater the surface area the faster the ice cube will melt.
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 happens to metal at 200 degrees Celsius?
At 200 C:-- All metals become hot to the touch.-- The electrical resistivity of all metals becomes greater than at room temperature.-- The volume of all metals becomes greater than at room temperature.-- Some metals, but not all, melt (become liquid).
How long does it take for ice to melt in water?
it takes 2 minutes for it to melt
Does vinegar melt ice in 2 seconds?
Under normal conditions vinegar is a liquid and so does not need to melt.
Can you over heat gold?
You can melt it and even vaporize it, but "overheat" - no.
How close would you have to be to the sun to melt?
Like around the chrona or something. And you would actually vaporize you-not melt you.
What is the synonym of evaporate?
Disappear, Disperse, dissipate, fade, melt, vanish, vaporize, weaken.
What type of forces must be overcome to melt or vaporize a substance?
There are different types of forces that must be overcome to either vaporize or melt a given substance. These forces includes the hydrogen bond, the London dispersion forces, and the dipole-dipole forces.
What happens if you put porcelain over a safety flame?
It will melt at first and then slowly start to vaporize
How do the states of matter change based on thermal energy?
They melt (liquefy), freeze (solidify), vaporize, or condense.
How Close Can You Get To The Sun Before You Melt?
You would start to melt at around 4,400 miles above the Sun's surface, reaching temperatures of over 9,930 degrees Fahrenheit. As you got closer, you would eventually vaporize due to the extreme heat, radiation, and solar winds.
Is a nuclear bomb hot?
yes, it is so hot it caneasily melt sand and dirt and instantly vaporize metals
Can you actually say water can melt do you not have to be a solid to MELT?
Water can melt if it transitions from a solid state, such as ice, to a liquid state due to an increase in temperature. The term "melt" refers to the change in physical state from solid to liquid, regardless of the initial form.
What is the point of the range?
The difference between the temperature at which the sample begins to melt and at the temperature at which the sample completely melted-
What does make ice melt?
An ambient temperature that is greater than the ice will cause it to melt.
How much heat is necessary to vaporize 500 grams of ice at its freezing point?
The heat required to vaporize 500 grams of ice at its freezing point is the sum of the heat required to raise the temperature of the ice to its melting point, the heat of fusion to melt the ice, the heat required to raise the temperature of water to its boiling point, and finally the heat of vaporization to vaporize the water. The specific heat capacity of ice, heat of fusion of ice, specific heat capacity of water, and heat of vaporization of water are all needed to perform the calculations.
