The air cell increases in size during incubation at a rate that depends on temperature and humidity as moisture evaporates from the egg. The drawing shows the normal size of an egg's air cell at 7, 14, and 18 days of incubation. Size of the air cell in the egg on the 7th, 14th, and 18th day of incubation.
A specific heat capacity is the amount of energy necessary to increase the temperature of a kilogram of that substance by one kelvin. Molar heat capacity is the amount of energy necessary to raise one mole of substance by one kelvin degree. One mole of a substance is exactly 6.02x10 23 atoms or molecules of that substance.
These simple steps probably look complicated at first glance, but relax, they will all become clear. 1  Balance the equation. 2  Convert units of a given substance to moles. 3  Using the mole ratio, calculate the moles of substance yielded by the reaction. 4  Convert moles of wanted substance to desired units.
