It depends on why you want to melt the cheese.
There are very many types of cheese, and methods of melting vary with each cheese and the use to which you want to put the melted cheese.
Perhaps you're making a cheese fondue? Gruyere is a classic Swiss cheese used for fondue; simply shred or cube it and melt in a pan on medium heat with garlic, wine, and other ingredients such as flour for thickening and liqueur and spices for flavouring.
Emmenthaler is another classic cheese for fondue, but most cheeses, from Cheddar to Brie can be used. Serve by dipping cubes of toasted bread, or pieces of cooked meat, or other small appetizing morsels, into the warm cheese mixture.
If you're thinking of some other way of cooking or serving a dish which involves melting cheese, try checking recipes which either use the particular cheese you're considering and/or which cover the particular method you have in mind.
Here is a quick and simple way to enjoy melted cheese: toast some bread, cover it with slices of cheese (Cheddar is good), and put it under the grill (broiler) until it melts.
Cooking cheese this way gives a lovely rich finish; it's hard to believe ordinary cheese can become so luxurious under a grill. If you want to add extras, such as mushrooms, put them on the toast before you top with cheese (otherwise they'll dry out).
Tomatoes and other additions can go on top of the cheese.
I wouldn't recommend processed cheese for melting; the results are likely to be unsatisfactory.
All cheeses melt, but some (such as cheddar) release oils during the melting process. If you want to avoid this, and you are attempting to make a cheese sauce, try this:
Make a roux (pronounced "roo") using equal parts of any form of fat (butter, margarine, meat renderings/drippings) and flour. Heat the fat until it is melting, but not smoking (this is where butter works best). Stir in the flour until it forms a thick paste.
For a white sauce, now add just enough milk to smooth it, stirring all the time...it should resemble a thick gravy. For a darker sauce, stir until the flour colors as desired, from a light gold to darker golden-brown, then add the milk.
Add shredded cheese a little at a time, stirring constantly, until it melts. Once you remove it from the heat, cover it or a skin will form on top.
Add it to other dishes such as potatoes or vegetables as soon as possible.
Yes, because the heat of dissolution in water of NaCl is released and the freezing point of water lowered.
If you heat NaCl to 801 degrees C, it will melt and if heated to 1413 degrees C, it will boil. You can definitely melt salt in a Bunsen burner flame in one class period, but heating it to boiling would take some time.
Solid sodium chloride has a structure where each Na is attracted to the six Cl that surround it and vice versa, to make it melt you must provide enough energy to allow these bonds to be rearanged so that the atoms can move around. Once you break all of the bonds the NaCl will evaporate.
Table salt (NaCl) is an ionic solid. Ionic solids are held by electrostatic forces of attraction. These forces are very strong and account for the high melting point of NaCl.
If you heat it to 801 degrees Celsius, it melts.
Table salt (NaCl) melts (or freezes) at 801o C. Salt is difficult to melt because it is an ionic compound. Ionic bonds are the strongest.
1 mole NaCl = 58.44g NaCl0.48mol NaCl x 58.44g NaCl/1mol NaCl = 28g NaCl
Solid sodium chloride is not an electrolyte; water solution of NaCl is an electrolyte (also melted NaCl).
Glucose (Melting point: 146° C) will melt faster than NaCl (Melting point: 801° C)
I'm going to assume that you mean 23.34g of NaCl. 1 mole NaCl = 58.442g NaCl (the atomic weight of Na and Cl in grams) 23.34g NaCl x (1mol NaCl/58.442g NaCl) = 0.3994mol NaCl
It's a mix of mostly NaCl and a little CaCO3
1 mole NaCl = 58.443g NaCl = 6.022 x 1023 formula units NaCl 3.6g NaCl x 1mol NaCl/58.443g NaCl x 6.022 x 1023 formula units NaCl/mol NaCl = 3.7 x 1022 formula units NaCl
