The hot plate would heat up the salt water and cause the water to evaporate, leaving salt crystals behind. If the water vapour was led off and condensed back into water by cooling, the water would be suitable for drinking.
first get a see through plastic cup then fill it up with warm water and salt don't mix then then put a smaller plastic cup fill less then half with cold water put the small cup in the big one don't let it tilt taste the salt water with your pinkie cover the all of the outside in plastic wrap after a day taste the salt water again if you did it right the salt water should be drinkable water ..................................................................... PS never let the small cup tilt and keep the cup under the sun
A hot plate can separate salt and water by vaporizing the water and leaving only the salt that was in solution behind.
yes because the heat from the plate will make the salt dissolve/disappear
Yes, place a dish of salt water on a hot plate and allow the water to be gently evaporated away. The result will be salt crystals remaining in the dish.

You filter the mixture using a filter paper. By this the salt solution will get separated from glass bits. Then you take the salt solution and heat it. The water will get evaporated leaving salt behind.
the hottter the temperature the faster salt dissolves
Sugar sinks at the same rate in warm or cold water. Sugar dissolves faster in warm water.
Salt dissolve quicker in hot water because it practicaly melts the salt there fore making it quicker.
The best way to safely microwave a hot water bottle is to heat the water in a separate microwave safe container in the microwave and then put the microwaved, hot water into the water bottle.
A hot plate will separate salt water.
Its a hot plate
I believe it is a hotplate
You heat it hot enough to evaporate the water and end up with salt.
Look at each of the options and really think about what each one would mean and need. To separate a mixture of salt waterA magnet - There is no metallic substanceB balance - There is nothing to weighC funnel - A funnel can direct water away, but the salt is IN the water.D hot plate - If you heat a salt-water mixture, the water will evaporate, and the salt will crystallize and be left behind. So I would choose D.
Dont get me wrong, but you seem to be asking how to separate salt from water. I think if you evaporate water, the salt cannot evaporate, and it stays behind. However, if the light is really hot, it will evaporate the salt along with the water. (Example: If you put salt and water in a dish and hold it on top of a lit candle, the light is hot enough to evaporate water, but not hot enough to evaporate salt.
To separate those three components you must first separate the sand from the water. The easiest and simplest way is to pass the water through a filter. This will leave you with the hot salt water. From here, all you have to do is evaporate the water so that only the salt is left. If you need to collect the water you can boil the water in a pot with a lid, slightly ajar, and let the condensed water collect in a separate container.
If a saline solution (dissolved salt in water) is gently heated, the water will evaporate, leaving salt crystals behind. If the water vapour is captured and condensed, the result is drinking water. The heat used can be a hot plate on an oven, or the warmth from the Sun's rays. Either way, heat will cause the water to evaporate, leaving salt behind.
First you must dip the rock in the water(hot) and that will make the salt and water into a mixture...this makes salt wateruse simple evapuration to separate the salt from the water!Hope i helped!!
Yes it can, the heat will evaporate the water, leaving behind salt crystals. (Be carefull as when heating the water with the dissolved salt in, the hot water can "spit" and it can hurt abit,) :} Hope this helped x
If the water was pure and had no salt already mixed in it then the same 20 grams of salt would be left, as salt doesn't evaporates on the temperature at which water does evaporates.
a magnet or hot plate
