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.
So the problem is that, when we compare amounts of one substance to another using moles, we must convert from grams, since this is the information we get from balances. There are three steps to converting moles of a substance to grams: 1  Determine how many moles are given in the problem. 2  Calculate the molar mass of the substance. 3  Multiply step one by step two.
