T K = ºC + 273
T = 63 + 273
T = 336 K
hope this helps!
Answer: Option (a) is the correct option.
Explanation:
In order to travel, sound does need a medium. The more closer the particles of a medium, the better sound can travel through it. Therefore, in solids sound travels very quickly because in solids particles are closer to each other. As a result, they can easily transmit the energy from one particle to another.
Thus, it becomes easier for sound to travel through it. On the other hand, in solids sound can travel in both longitudinal and transverse waves.
Hence, out of the given options, sound travels in transverse waves requires a medium to travel through is the correct option.
A reaction is when two or more pure substances combine with each other to form another identity of pure substances. In general from, it is written as:
A + B → C + D
The substances A and B are the reactants, while the substances C and D are the products. Therefore, in a reaction, the products are found at the end or right side of the reaction.
I believe the answer is B.
Answer:
V₂ = 448.44 L
Explanation:
Given data:
Initial volume = 5.00 L
Initial temperature = 24°C
Final volume = ?
Final temperature = -27000°C
Solution:
Final temperature = -27000 + 273 = 26727 K
Initial temperature = 24 +273 = 297 K
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 5.00 L × 26727 K / 297 k
V₂ = 133635 L.K / 298 K
V₂ = 448.44 L
