Answer: option B. The kinetic energy of gas molecules is directly proportional to the Kelvin temperature of the gas.
Explanation:
The kinetic theory of gases explains the behavior and properties of gases from a molecular perspective.
Specifically and explicity, the kinetic theory of gases states that gases are constituted by particles (molecules) and that the average kinetic energy of the particles is proportional to the absolute temperature (Kelvin scale) of the gas. Furthermore, the temperature of all the (ideal) gases is the same at a given temperature.
Hence, you know that the higher the temperature of the gas, the higher the kinetic energy and the average speed of the molecules.
Other postulates of the kinetic theory of gases are that: i) the volume of the particles is neglectible; ii) the particles do not exhibit intermolecular attraction or repulsion; iii) the particles are in continuous random motion in straight paths, until they collide with other particles or the walls of the vessel, and iv) the collisions are elastic (the energy is conserved).
Substance P replaces X in the compound XY
this is the characteristic of decomposition reaction
Answer:
The person on the right will move backwards/to the right.
The reason is because the person on the left is pushing with more force than the person on the right
The Milliliters that occupy when its pressure is 755 mmhg is calculated using Bolyes law fomula
that is P1v1 = p2 V2
p1= 735mmhg
V1= 350 Ml
P2= 755 mm hg
V2= ?
from the formula above V2 is therefore= p1V1/P2
= 350 x735/755= 340.73 Ml
False
Explanation:
A plant will die after being exposed to poison does not represent a physical change. A physical change is one that alters the physical state of matter and leads to no formation of new substances.
- The plant dies due to chemical changes in its structure.
- The poison will react with the chemicals in the system of the plant to produce new harmful ones.
- In a chemical change, new kind of substance forms in the plant and the change is irreversible.
