Answer:
decomposition
Explanation:
becoz it is a single compound and it under goes to give two give two or more products
K.E = mgh at bottom
K.E = 0.18*10*45
K.E = 81J
K.E at the bottom will be equal to P.E at hight.
A)0.167 atm
B)0.437 atm
C)0.886 atm
D)149 atm
Answer:
The new pressure is 0.167 atm
The correct answer is option A
Explanation:
Step 1: Data given
Volume of the gas = 22.4 L
Pressure of the gas = 0.265 atm
The volume increases to 35.52 L
Step 2: Calculate the new pressure
P1*V1 = P2*V2
⇒with P1 = the initial pressure = 0.265 atm
⇒with V1 = the initial volume = 22.4 L
⇒with P2 = the new pressure = TO BE DETERMINED
⇒with V2 = the increased volume = 35.52 L
0.265 atm * 22.4 L = P2 * 35.52 L
P2 = (0.265 atm * 22.4 L) / 35.52 L
P2 = 0.167 atm
The new pressure is 0.167 atm
The correct answer is option A
melting and sublimation
condensation and vaporization
sublimation and boiling
Answer:
Condensation and vaporization
Explanation:
At a given temperature, molecules of a liquid move into the gas phase (vaporization) and the molecules of the vapour can move back into the liquid phase (condensation).
