Answer:
V₂ = 0.62 L
Explanation:
Given data:
Initial volume = 2.4 L
Initial temperature = 25°C
Final temperature = -196°C
Final volume = ?
Solution:
Initial temperature = 25°C (25+273 = 298 K)
Final temperature = -196°C ( -196+273 = 77 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 = 2.4 L × 77 K / 298 k
V₂ = 184.8 L.K / 298 K
V₂ = 0.62 L
Answer: A material that readily transmits energy is a conductor, while one that resists energy transfer is called an insulator .
i hope this will help u
pls add me as brainliest
If you mean temperature wise then it’s due to the clouds absorbing most of the sunlight, less clouds let’s more light through
Answer:

when a substance undergoes a change of color it is an indication that it was chemical
Answer:
Explanation:
Hello!
In this case, since this a problem in which the cold water is heated by the hot water, we can write:
Thus, by plugging in the mass, specific heat and temperatures, we obtain:
Now, we can also write:
Then, after applying some algebra, it is possible to obtain:
If we plug in, we obtain:
Best regards!
