Answer:
answer
<u>Cold Front - a zone separating two air masses, of which the cooler, denser mass is advancing and replacing the warmer. </u>
<u>Warm Front - a transition zone between a mass of warm air and the cold air it is replacing. </u>
<u>Stationary Front - a front between warm and cold air masses that is moving very slowly or not at all.</u>
It would be +3
Since the number of protons and electrons must be equal in an atom for it to be neutral, if it looses electrons it becomes positively charged ion and if it gains electrons it becomes negatively charged ion.
The total energy required for this conversion is equivalent to the sum of the energies that are used. There are three steps:
1) Heating of liquid acetone
This used 628 J
2) Evaporation of acetone
This used 15.6 kJ or 15,600 J
3) Heating of acetone vapors
This used 712 J
Adding these quantities,
Total energy = 628 + 15,600 + 712
The total energy required was <span>16940 Joules of 16.94 kJ</span>
The sun light is balanced by heat radiated from earths atmosphere
