because 15 is a higher degree
That depends on how hot the water is in the cup. Use the thermometer to measure it and see.
fill up a beaker about 3/4 of the way up. Then turn on the hot plate and place the beaker on top of it. Set the hot plate to high (or 10) and wait for the water to boil. When the water is done boiling, turn down the hot plate to about 7 to maintain the temperature
When hot metal is added into the water then the metal looses its energy into the water and this heat is gained by the water, so the temperature gets increases when hot metal added into it i.e final temperature is greater than initial temperature of water.
When hot water is mixed with cold water, the overall temperature of the mixture will be between the initial temperatures of the hot and cold water. The hot water will transfer heat to the cold water, resulting in a gradual temperature equilibrium.
A Jolly Rancher will dissolve faster in hot water compared to room temperature water. The higher temperature of the hot water increases the rate of the dissolving process, allowing the candy to break down more quickly.
Saudi Arabia is an incredibly hot country. In the dead of winter, it is still around 15oC.
Not being at the correct temperature spoils paintballs. Most paintballs need to be about 15oC and below 30oC. If they go outside these temperatures for any length of time the will spoil. If they get to cold they get fragile and will normally break before they leave the gun and too hot and they swell up, still together and become bouncy. They will normally then get stuck in the elbow or stuck in the barrel.
15oC = 59oF
You can only "warm" anything from a lower temperature to a higher temperature. To warm something from 42oC the temperaure will become higher than 42oC. To get to 15oC you will have to COOL it i.e. extract heat to get to a lower temperature.
Because if it is hot, we don't need it. It adjusts to the temperature
Evaporation occur at any temperature but a high temperature favors evaporation.
You need water that is room temperature. If the water seems too cold put more hot water in, if too hot put more cold in.
The atmosphere. The ozone layer absorbs UV radiation, and atmosphere also controls temperature through the greenhouse effect, which allows the earth's temperature to be suitable for life. If there was no greenhouse effect then the earths average temperature would be -14oC instead of the actual 15oC.
There does not need to be a certain temperature if your hot tub will not be in use. In fact you should drain your hot tub if you wont use it for a while, so it wont be a danger to children or pets, or inclement weather.
It depends on how hot I want it to be. If I want regular out-of-the-tap hot water, I stick my finger in it quickly and then shout and wave my hand about when it's actually hot. If I need boiling water to be a certain temperature, I measure the temperature with a candying thermometer.
