Why is ice a good cooling agent?
because the ice can cool you down and its frozen and frozen things are cool and because ice has the ability to absorb more heat energy than water in scientific terms ice has a large latent heat of fusion which makes it a better cooling agent than water
How much energy does it take to melt ice?
Heat because Ice and water would thaw out and begin to heat up
Why does ice melt faster in plastic than paper cup?
Since plastic is bad conductor of heat it does not allow free passage of heat...Its molecules (each of them) hide some heat energy and pass on the rest whereas in the case of metals which are very good conductors(in general) of heat the molecules allow better passage of heat . Since less heat passes on to ice when coated with plastic than metals, the ice melts slower in plastic than metals.
How much electricity does it take to melt 1 cubic meter of ice?
This is too complicated to give a complete answer, but how about this to start with. When ice melts it changes it's state from solid to a liquid . Water can have a temperature of zero centigrade and ice can have a temperature of zero centigrade . To change it's state from ice to water, or water to ice there is a considerable amount of 'heat' involved . Heat is measured in a unit called the Calorie . To change ice back to water it must absorb heat energy. It requires about 80 Calories of heat per gram of ice, just to melt it all. This heat energy is called the 'Latent heat of Fusion'. There is no change in temperature whatever, when the zero degrees Ice changes to zero degree water. There is simply a lot of 'heat' exchanged. I will let you calculate how many grams of ice in a cubic Metre, but it is an enormous quantity of grams . When you get the answer, multiply it by 80 and that is the number of calories of heat energy needed to do the job. Now you will need to calculate the number of Watts of electrical energy needed to perform the task of supplying all that heat. There is a direct relationship between watts of electrical energy, and calories of heat energy. Be very aware that temperature and heat are totally different things, having totally different units.
Which local materials will keep the ice from melting fast?
The Answer: Alcohol The ice begins pulling heat (energy) from the alcohol. It is not the ice cooling the alcohol it is the alcohol that transfers heat to the ice (solid water). The ice draws heat from the warmer alcohol inducing the ice to melt. This is because the freezing point of the alcohol is much lower than the ice. If we were to keep the ice in the glass (by adding more) the rate of melting of the ice would slow because the heat (energy loss) of the alcohol has been reduced. But it would indeed continue to draw heat from the alcohol just more slowly. {this of course would require no atmosphere heat (energy) from contacting either the ice or the alcohol.} If we had solid CO2 (dry ice) it could draw enough energy (heat) from the alcohol to freeze it solid. {this of course would require no atmosphere heat (energy) from contacting either the ice or the alcohol. Plus a lot of dry ice to replace what has melted or sublimated away.} By: Mark L. Vizon
Is ice or heat better for soreness?
Ice
Is ice or heat better for a sore heel?
both put ice on and after the ice starts numbing the heel but heat on it
Is ice or heat better for cold sores?
Ice use is better for cold sores.
Does sand melt ice?
Sand abosorbs light better then ice. So the heat melts the ice.
Where does the heat go when water changes to ice?
The heat goes back to air
Should you put ice or heat for sciatica pain?
It really depends on which type of injury occurred so that you can determine whether to use heat or ice. If the position is no pain-free, use ice. If the position is pain free with movement, use heat.
Should you put heat or ice on a pinched nerve?
Heat, anti-inflammatories, and a muscle relaxer if you've got it. Like pinched nerves in the back (from disk herniations), a lot of the real pain from pinched neck nerves (which can indicate a disk problem in the cervical spine as well) comes from the muscles spasms caused by the nerve being compressed. Heat helps loosen the muscles, and allows for increased blood flow to the area to heal. If you do use cold (it does help some people, but it can irritate already sensitive nerves) use it for short periods, then add heat. What it boils down to is that the combination reduces the inflammation, relaxes the muscle spasms, and increases blood flow to promote faster healing.
Is ice or heat better for a tooth abscess?
if your intention is to drain the abscess, heat. for pain relief, cold.
Do you put ice or heat for swelling on my arm?
I think you will be better off using a cream and ice! ( that's my opinion )
Why you need to apply heat or ice to the patient with low back pain?
Use ice for injuries to calm down any damaged tissues that are inflamed or swollen. Use heat for sore muscles, chronic pain and stress.
Which is better for melting ice CaCl3 or NaCl?
Calcium chloride is better (the solubility heat is greater) but is more expensive.
What is the best treatment for muscle spasms?
Muscle spasms occur when a muscle is torn or overstretched. It starts with a muscle strain, known as a pulled muscle. The strains usually heal with time but if the pain is unbearable, patients may need to take pain medication along with applying ice or heat to relieve the pain.
