Answer: True
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
is positive when randomness increases and
is negative when randomness decreases.
When the solid changes to liquid to gas ,the randomness of particles increases and hence
is positive and thus the entropy increases.
The answer is either band theory or covelent theory but I'm pretty sure it's covelent theory
90 grams due to laws of conservation of mass. Output mass = input mass. Mass can never be created or destroyed.
Answer:
267.57 kPa
Explanation:
Ideal gas law:
PV = n RT R = 8.314462 L-kPa/K-mol
P (16.5) = 1.5 (8.314462)(354) P = 267.57 kPa
