The principle of ice water bath, the principle of ice making from hot water

For most elite athletes, soaking in a bucket of 12-15° ice water after training is a daily means of quick recovery and reduces muscle pain. When training or competing, the best track athletes and rugby players mostly use this method.

1.First, open the package and check if there is a problem with the water heater. After inspection, we will find that there will be two hooks on the back of the water heater that are used to allow the water heater to hang on the wall.

2.Once you've seen the hooks, dress up and measure the distance between them, measure the length and width of the water heater, and draw on the wall where you need to blink. 3.

After painting, we can erect the orange and start drilling. Basically, some water heaters are fitted with expansion screws. If not, you need to buy them.

It's better to buy a bigger one, which will be stronger. 4.After punching the hole, use a hammer to hammer the expansion screw into it to make the expansion screw more firm.

Then tighten the expansion screw with pliers or a wrench so that the water heater can be hung up. 5.Then lift the water heater.

Basically, it is recommended that two people carry it, so that it is easy to hang. Then, just align the hook on the back of the water heater with the expansion screw, hang it up, and the water heater is secured. 6.

Next, connect the entrance and exit. Here, the buyer needs to buy a 40-wide hose and connect it to the water inlet of the water heater from its own water outlet, and then connect the water inlet of the water heater to its own water inlet, and then plug it in for heating.

They are all low-temperature bathing methods, but the coolant is different and the low temperature amplitude is different. The former coolant is ice water, and silver can only be reduced to about 0 degrees, and the latter coolant is a salt solution, and the temperature can be reduced to below 0 degrees.

The cooling principle of the ice salt bath and the freezing point of the dissolution shed liquid.

Decline. When salt and ice are mixed evenly, the ice melts slightly into water due to the absorption of ambient heat, and the salt dissolves when it meets water, so that the surface water forms a concentrated salt solution. Since the freezing point of the concentrated salt solution is lower than that of pure water, and the concentrated salt solution and ice coexist in the system, the temperature opening of the system must be reduced to maintain this coexistence state (the coexistence temperature of the concentrated salt solution and ice should be lower than that of pure water).

The cooling principle of the ice salt bath is related to the decrease in the freezing point of the solution. When salt and ice are evenly mixed together, the ice melts slightly due to the absorption of ambient heat.

It becomes water, and the salt dissolves when it meets water, so that the surface water forms a concentrated salt solution. Since the freezing point of the concentrated salt solution is lower than that of pure water, and the concentrated salt solution and ice coexist in the system, the temperature of the system must drop to maintain this totality.

Storage (the temperature at which the concentrated salt solution and the ice coexist should be lower than the freezing point of pure water). This will cause more ice to melt into water to dilute the concentrated salt solution, reducing the temperature of the system due to a large amount of endothermy during the melting process.

The cooling principle of the ice salt bath is related to the decrease in the freezing point of the solution. When salt and ice are evenly mixed together, the ice melts slightly into water due to the absorption of environmental heat, and the salt dissolves when it meets water, so that the surface water forms a concentrated salt solution. Since the freezing point of the concentrated salt solution is lower than that of pure water, and the system is where the concentrated salt solution and ice coexist, the temperature of the system must drop to maintain this coexistence (the coexistence temperature of the concentrated salt solution and ice should be lower than that of pure water).

Ice water bath even though.

Ice water mixed with answers.

Simply put, it can be in a beaker.

Add ice cubes and water. At this time, ice and water coexist, and the temperature of the system is a constant freezing point temperature: zero degrees. Feast filial piety.

If the substance you want to collect has a low boiling point, you can heat it up and introduce it into the flask with a catheter, which can be placed in an ice water bath.
