Guessing what you meant here; if it's wrong, please clarify. Normally this is done after a filtration. The filtrand is rinsed with solvent to wash off any impurities that may be left. It's rinsed with cold solvent to minimize the amount of filtrand that dissolves.
the answer to this one is, you cant dissolve a solid..like wood well you could with some chemicals that would eat away at the solid but if you mean putting it in some water and heat it up then no you can not.
Solid oxygen. Though it might make one hell of a bang ;) Formed at -218 Celcius, or 54 Kelvin.
To prepare a parts per million (ppm) solution from a solid, you would first need to accurately measure the mass of the solid compound. Then, dissolve this solid in a known volume of solvent to make a specific concentration solution. Finally, calculate the ppm concentration by dividing the mass of the solid compound by the total mass of the solution and converting it to ppm.
This concentration is known as molality, and it is expressed as moles of solute per kilogram of solvent. To convert from moles of solute per 1000 grams of solvent to molality, you need to convert the mass of the solvent from grams to kilograms before calculating the molality.
To prepare 1mm solution from 100mm NaNO2, you will need to dilute the stock solution by a factor of 100. You can do this by taking 1 mL of the 100mm solution and diluting it to a total volume of 100 mL with the appropriate solvent (such as water).

A cleaning solvent would help to get rid of the grit and dirt that are sealed on the metal grill by the temperatures of cooking on it. It is always a good idea to rinse completely before cooking on the grill again.
keep at below 40 degrees F. rinse thoroughly in cold water
To prevent it from overcooking. Cold water will stop the cooking process. However, you need not rinse it if you want to serve the pasta immediately. -------------------------- Rinsing pasta removes the starch. If serving hot pasta, you want the starchy coating to remain in order to make your sauce stick. If you are making a cold pasta salad, you will want to rinse the pasta in cold water first.
Gasoline does not have a solvent, as it is commonly used, and it does not need a solvent. This is because gasoline is not a solid that needs dissolving, it is a liquid hydrocarbon already and is a solvent more than it can ever be a solvent.
To calculate the molality of the solid solution, you need to first find the moles of chromium and iron separately. Then, determine the total moles of solute (chromium) and solvent (iron). Finally, divide the moles of solute by the mass of the solvent (in kg) to get the molality. Molality (m) = moles of solute / mass of solvent (kg).

The compound that you are trying to recrystallize is soluble in hot solvent but relatively insoluble in cold solvent. You also must remove an impurity that is insoluble in hot and cold solvent. The first filtration (a hot filtration) is to filter out the impurity. The second filtration (a cold filtration) is to filter out the (hopefully pure) recrystallized compound.

because you need more solvent than solute, so you need more to steel i guess
NaCl--table salt--is typically look at as the solid solute within a solution. The osmotic pressure you need is for the solvent which will need to be calculated I believe. The Van Hoff Factor for NaCl (1.9) is probably what you needed
it could be die in the night or mite be to cold for it so you mite need more bedding
