Room temperature air. The water keeps it fresher.
Its ok as long as you let the water cool to room temperature before adding the water back to the bowl, or adding the betta to the water. Also, it is completely unnesseary to boil before putting in your betta's bowl.
Well, if you have a bowl of water and get a salt shaker you can exame. So fill the bowl of water with the salt shaker and skake a little salt out, not to much or not to little. Then, the water soon will evaporate wich means that the salt will be left behind in the bowl and the water will be in the air. The salt is to heavy to go into the air so thats why it will be left behind in the bowl. So the its faster in a way. :D
Convection currents are currents of fluid that move because of a difference in temperature, and therefore energy. When a fluid (let's say water, because we're talking about a bowl of pasta here) heats up closer to the source of heat, it will increase in temperature and energy. Cooler water, which is lower temperature and energy level than warmer water, will gradually sink, which causes the warmer water to rise. When the warm water cools and the cool water warms, the molecules sink and rise respectively. This process continues until the source of heat is extinguished. This is what makes your pasta bowl water move about. Have fun cooking!
Simply it's because Heat and Temperature are not interchangeable. They're not the same thing. Heat is a form of energy. Temperature is not. When heat encounters a substance, it can change the state of the substance or raise it's temperature. Temperature is only a measurement that relates to the molecules kinetic energy. But it says nothing about potential energy. Consider for a moment how much TOTAL potential heat energy is in even a bowl of warm water. You would need a lot of energy to raise a cold bowl of water to that same warm temperature? Could the candle do it? Possibly, but over a long period. That flame might be hot, but it doesn't possess the same energy? Btw: Water has a considerably high Specific Heat, which is the amount of heat (energy) required to raise it's temperature by 1 degree for 1 gram
Salt on it's own will not make ice cream faster, however adding salt to a water + ice solution causes a chemical reaction which will lower the overall temperature to less that that of either the water or the ice which would then let a container in that solution reduce it's temperature a lot faster than usual (that is what helps make the ice cream faster); I will explain: Water freezes at 0 degrees. By adding salt to water we now create a solution that is no longer water. This salt/water solution has a lower freezing temperature than water alone. Now we add ice to this solution. As the salt dissolved in the water starts the 'melt' the ice (the reason I have used quotes around 'melt' is because we are effectively seeing the ice melt but what we are actually doing is converting it into a liquid which will no longer be frozen at 0 degrees), a chemical reaction takes place which results in the energy used to 'melt' the ice being expelled as heat, therefore reducing the temperature of the whole salt/water+melting ice combination to as low as -22 degrees. The same trick can be easily used to cool cans and bottles of drink very quickly - just get a bowl with some water and plenty of ice in it and add a couple of handfuls of salt. Stir it for a few moments and then put some cans of drink in it. About 5 minutes later, those drinks should be lovely and cold!
Ice will melt faster in a bowl of alcohol compared to a bowl of water due to alcohol having a lower freezing point than water. The lower freezing point of alcohol allows it to absorb heat more quickly from the surroundings, leading to faster melting of the ice. Additionally, alcohol has a lower heat capacity than water, meaning it requires less energy to raise its temperature, further contributing to the faster melting of the ice in alcohol.

To quickly bring eggs to room temperature, you can place them in a bowl of warm water for about 5-10 minutes. This will help them reach room temperature faster and make them easier to use in recipes.
The ideal water temperature for a fish bowl is typically between 75-80 degrees Fahrenheit. It is important to maintain a consistent temperature to ensure the health and well-being of the fish.
Cats may put their paw in the water bowl to test the water temperature, play with the water, or to drink water more comfortably.

Heat generally tends to flow from higher temperature to lower temperatures. In this case, the cup of milk is hotter than the bowl of tab water. Hence the temperature of water increases, and the temperature of milk decreases. This process continues till both the temperatures are equal.
Water temperature in the aquarium should be kept in the 75-80 F range.
Sodium catches fire at room temperature. So it is kept in bowl of cold water.
The temperature of a finger bowl is typically lukewarm, meaning it is neither hot nor cold. It is meant to be comfortable for rinsing fingers after a meal.
It has more dense that water. when you take off the skin your loosing every thing that is keeping the apple up. so when the apple all the water in the apple are being weighed down,
Ice will melt faster in room temperature air than in room temperature water due to the difference in thermal conductivity. Air is a poorer conductor of heat than water, which means that heat transfer occurs more slowly in air compared to water. Therefore, ice will melt more quickly in room temperature air.
