Sound needs a medium to propagate through and this medium which is moves through is the air. The colder the temperature is, the less excited (meaning kinetic energy) the air particles will be meaning that the sound wave will travel slower. In the sahara desert, since the temperatures are warmer, and more excited, the sound will propagate faster through the air.
*Note that sound waves rely on vibration to move and if the air is hotter the molecules in the air are vibrate more than compared to lower temperatures.
Answer:
C carbon identified as one c=1 and o oxygen=2 atoms/molecules
Explanation:
Answer:
C).
Explanation:
As we know if temperature of the gas remains constant then
now we will have
P = initial pressure due to gas
initial volume of the gas is
now we know that side of the box is increased by 4 times
so new volume is
now we have
now we have
In my personal opinion, avoiding in not an effective conflict management strategy. When you are avoiding a conflict, you are really just pushing it to the side and it will need to be dealt with sooner or later. Avoiding a conflict is also ammeter thing to do as well, you should take responsibility and handle any situation.
Answer: Option (a) is the correct answer.
Explanation:
Entropy is defined as the degree of randomness present in a substance. This means that more randomly the atoms in a substance are moving more will be entropy of the substance.
Entropy of a substance increases with increase in temperature.
For example, when a piece of wood is burned then its molecules will gain kinetic energy and hence, they start to move randomly from one place to another.
As a result, there will occur an increase in its entropy.
Thus, we can conclude that when a piece of wood is burned then its entropy increases.
