Danger: heat cramps and heat exhaustion are likely; heat stroke is probable with continued activity. The heat index is a way of describing what the temperature "feels" like (similar to Wind Chill). In desert regions, such as Arizona and New Mexico, we often see “feels like” temperatures lower than the actual temperature. And as we heard from meteorologist Morgan Miller in an earlier episode, local weather forecasters usually know what estimates work best for their region and can combine that knowledge with their personal experience to give you the best “feels like” estimate. You can calculate the dew point in three simple steps: Select the temperature unit between Fahrenheit (°F), Celsius (°C), or … Different weather providers have different names and methodologies for calculating the apparent temperature. As described above, the heat index is the temperature equivalent perceived by humans as a result of air temperature, relative humidity, and wind speed. El Paso Climate Data Most of us have a sense of what a temperature of 75 degrees Fahrenheit means, but add a brisk wind and you will feel colder. To calculate the amount of heat released in a chemical reaction, use the equation Q = mc ΔT, where Q is the heat energy transferred (in joules), m is the mass of the liquid being heated (in grams), c is the specific heat capacity of the liquid (joule per gram degrees Celsius) and ΔT is the change in temperature of the liquid (degrees Celsius).
