The best and most correct answer among the choices provided by your question is the fourth choice which is "<span>Heat moves through conduction, convection, and radiation."
</span>Heat transfer<span> is the exchange of thermal energy between physical systems. The rate of </span>heat transfer<span> is dependent on the temperatures of the systems and the properties of the intervening medium through which the</span>heat<span> is </span>transferred<span>. The three fundamental modes of </span>heat transfer<span> are conduction, convection and radiation.</span>

Answer:
A Cake Baking
Explanation:
All of the other options are physical changes because you can always bring it bake to it's original state unlike a cake baking you can't separate the flour, sugar, and eggs as it was before.
It is false, because models don't help you get a better understanding of the world, they help you better understand what you are trying to get from it like a weather model, it helps us see the weather because it is a visual so people would know what type of weather is where.
The balanced equation that illustrates the reaction is:
2C4H6 + 11O2 ......> 8CO2 + 6H2O
number of moles = mass / molar mass
number of moles of oxygen = 2.1 / 32 = 0.065625 moles
Now, from the balanced equation, we can note that:
11 moles of oxygen are required to produce 6 moles of water.
Therefore:
0.065625 moles of oxygen will produce:
(0.065625*6) / 11 = 0.03579 moles of water
number of moles = mass / molar mass
mass = number of moles * molar mass
mass of water = 0.03579 * 18 = 0.644 grams
Answer:
3, non polar causes the molecule to not have a twin molecule. polar just means it has a correspondent
