A warm front is the transition zone which develop in a region where warm air replaces the cold air. The air behind the warm front is warmer than air in the front. When the warm front reaches a region with colder air, the cold air gets warm and more humid. Warm front brings changes in weather condition of a region. The increase in humidity in air results in rainfall and temperature becomes warm.

Therefore, a warm front heading toward Chicago will result in warm and rainy weather.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
