Why does it take longer to cook a large cheese pizza (400g) than it does to cook a small cheese pizza (150g)? Justify (support) your answer with information on the relationship between the mass (g) and thermal energy (kinetic energy) needed to change the temperature of an object.

Be sure to include what happens as thermal energy increases or decreases - be specific.

When the Large pizza is in the oven, it expands which means the heat from the oven will need to heat up more area. The Smaller pizza will still expand but it will not need as much heat at the large pizza.

Explanation:

Larger it is the more heat it needs.

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.
