Heat and Weather Forecast

The weather forecast is reported by various media. Forecasts generally report the temperatures and relative humidity of different regions of a country. The temperatures are quoted for us Brazilians in degrees Celsius, and their values ​​give us a reference to how much the molecules of a given body are agitated.

Some newspaper reporters or columnists who tell us the weather forecast often use the terms: “today goes it's very hot", and the information they want to give us is that "today will be a very hot day" or temperature high.
But what is heat? Heat is thermal energy in transit that always goes from the hottest to the coldest body.
By saying that today it will be very hot, they inform us that today there will be a lot of thermal energy in transit!
Energy is a greatness that cannot be created or destroyed, regardless of its form of manifestation; it can only be transferred or transformed.


Scientifically, the language cited by the informants of the time becomes incoherent, however, considering the target audience, the “popular language” or even formal becomes coherent.
