Question

Se informa que un arco eléctrico estabilizado con agua llegó la temperatura de 25600 °F. En la escala absoluta, ¿Cuál es la relación entre la temperatura y la de una llama de oxiacetileno (3500 °C)?

Answer 1

Answer:

Explanation:

Translation:

It is reported that an electric arc stabilized with water reached the temperature of 25600 ° F. On the absolute scale, what is the relationship between the temperature and that of an oxyacetylene flame (3500 ° C)?

Solution:

Temperature of the electric arc = 25600°F

Temperature of the oxyacetylene flame = 3500°C

The absolute temperatures are usually recorded in Kelvin. In order to compare the two given temperatures, a need to convert to Kelvin arises.

From celcius to kelvin we have:

     K = 273.15 + T°C

T°C is the temperature in degree celcius

For the oxyacetylene flame:

     K = 273.15 + 3500 = 3773.15K

From fahrenheit to kelvin, we have:

    K = $\frac{5}{9}$(T °F – 32) + 273.15

T °F is the temperature in degree fahrenheit

For the electric arc:

    K = $\frac{5}{9}$(25600 – 32) + 273.15 = 14477.59K

We can see that by expressing the two temperature on the same absolute scale, an electric arc is by far hotter than an oxyacetylene flame.
