The short answer is yes. Ever slip on ice when you know the temperature wasn't below freezing?
The air temperature is directly controlled by the amount of infrared radiated away from a surface, blackbody or not. Technically, air temperature is defined as the temperature at 2 meters, so you have to mix the air between 2 meters and right at the surface. So that's where your question comes in - if mechanisms of conduction and convection can't efficiently mix that loss of heat from the surface, then yes, this scenario would play out. Practically, it would have to be only a couple degrees above freezing though.
Note: I have actually observed this. An important condition is very still air so that there is no wind to aid convective warming of the water. It also helps if the air is very dry so that evaporation is encouraged - to add to the cooling of the water. (And, as previously mentioned, it is also necessary to have it close to freezing temperature.)
Yes, it is possible for electricity to be disconnected in freezing temperatures due to issues such as frozen components, power line damage from ice or fallen trees, or strain on the electrical grid during peak demand. It's important to have emergency heating plans in place in case of a power outage during freezing weather.
The temperature of the water will not change during a phase transition. If you have seen a graph of temperature versus heat input of water before, you can see that at the freezing point and the boiling point, the temperature remains constant while heat input increases. This is because during the phase transition (such as from solid to liquid), the heat put in will be used to separate the molecules and overcome the electrostatic forces between them, rather than to raise the temperature of the substance. Therefore, at the freezing point, it is possible to have both solid ice and liquid water at the same temperature.
Yes and no. Yes cola CAN freeze at a temperature under water because any drink WILL freeze from being to cold. Like my grandpa's coke was to cold that an iceberg grew in it. And NO it CAN NOT freeze lower then the temperature of water because most drinks can hold the coldness for as long as possible.
For a given temperature, Kelvin scale will show the highest value. However, a given temperature will be same on Kelvin, Celcius or Fahrenheit scale. E.g. At the freezing point of water, Kelvin will show 273.15 degrees, Celcius will show 0 degrees and Fahrenheit will be 32 degrees. That means, at freezing point of water = 00C = 273.15K = 320F
Snow in Brazil at 95 degrees is unlikely; it's possible that the reported temperature was incorrect or that the snow event occurred in a region with a different climate zone. Temperature needs to be below freezing (32 degrees Fahrenheit) for snow to form, so a temperature of 95 degrees is not conducive to snowfall.
Not with a thermometer, which had not yet been invented. It was, of course, possible to determine whether the temperature was below freezing or not without the assistance of a thermometer.
No, 0 degrees Celsius is freezing temperature. You can go into the negatives.
Yes, it is possible for the dew point to be below freezing. Dew point is the temperature at which air becomes saturated with moisture and condensation forms. If the air is very dry, the dew point can be below freezing, meaning that the air is not saturated with enough moisture for condensation to occur at temperatures above freezing.
No, but they are related. Absolute zero is the coldest possible temperature. Absolute temperature is the temperature above this coldest possible temperature - i.e., how much hotter is it than the coldest theoretically possible temperature. Celsius temperature isn't absolute. It starts from the temperature of freezing water, and it needs negative numbers for anything colder than that. Fahrenheit temperature isn't absolute. It says that zero is 32 degrees colder than freezing water, and it needs negative numbers for anything colder than that. Absolute temperature starts from absolute zero. Nothing is colder than that, so absolute temperature is never a negative number.
I think 1 degree Celsius is ideal. Not freezing, but as cold as possible before freezing. I once asked an organic farmer about what temperature to store some apples I had purchased. The 1 degree answer came from him.
Freezing is the act/process of freezing something. Freezing point is the temperature at which a liquid substance turns solid. This is due to the slowing down of its molecules due to lack of energy (no heat).
Yes, -100 degrees Celsius is possible. It is a temperature below the freezing point of water, which is 0 degrees Celsius. In fact, -100 degrees Celsius is equivalent to -148 degrees Fahrenheit. This temperature is achievable in certain environments, such as in laboratory settings or in extremely cold regions on Earth.
Celsius and Kelvin scales have the same unit, but they start at different temperatures. 0 Celsius is the freezing pt of water, but 0 Kelvin is absolute zero (the coldest temperature possible)
Negative values on the Fahrenheit and Celsius temperature scales represent temperatures below the freezing point of water. This indicates temperatures below zero degrees where water transitions from a liquid to a solid state. It is possible to have negative values on these scales because they are based on the properties of water and its freezing point.
Yes, it is possible to change a liquid into a solid by applying pressure and reducing temperature. By reducing the temperature and increasing the pressure, the kinetic energy of the molecules in the liquid decreases, causing them to come closer together and form a solid structure. This process is known as freezing or solidification.
The Celsius scale can give negative temperatures when measuring temperatures below zero degrees Celsius. This is because zero degrees Celsius is the freezing point of water, and temperatures below freezing are represented as negative values on the Celsius scale.
