Answer:
The answer is Avogadro's Law.
Explanation:
Avogardo's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." The derivation of Avogadro's law follows directly from the ideal gas law is:
where ;
V is the volume of the gas;
n is the amount of substance of the gas (measured in moles);
k is a constant for a given temperature and pressure
P is pressure of the environment
T is temperature of the environment
Answer:
Explanation:
Newton's law of cooling
Rate of cooling
Where To is the surrounding temperature
T is object temperature at any time t
now by removing proportionality sign
Now by separating variables
So
Where C is constant
C' is also a constant and it can be find by using boundary conditions.
