The amount of heat needed to increase the temperature of a substance by is given by where m is the mass of the substance, Cs is its specific heat capacity and is the increase of temperature.
If we re-arrange the formula, we get And if we plug the data of the problem into the equation, we can find the specific heat capacity of the substance:
The layer of electrically charged molecules and atoms which spans 40-250 miles above ground called ionosphere causes the display of the aurora and the reflection of radio waves back to earth.
