Answer:
El calor latente es la cantidad de energía requerida por una sustancia para cambiar de fase, de sólido a líquido o de líquido a gaseoso.
Explanation:
The sound produced is called wheezing. It is somewhat like a whistle except it's more course and you don't do it voluntarily like whistling, but rather it occurs because of obstructions. It can be either vocally or you can hear it when there are nasal obstructions when you are breathing through your nose.

Heat lost or gained, H = mc(θ₂ - θ₁)
Where m = mass, c = Specific heat capacity, θ₂= final temperature, θ₁ = initial temperature
m = 200g, c = 0.444 J/g°C, θ₁ = 22 °C (Since it was cooled).
H = 6.9 kj = 6.9 *1000J = 6900 J
6900 = 200*0.444* (θ₂ - 22)
6900/(200*0.444) = θ₂ - 22
77.70 = θ₂ - 22
θ₂ - 22 = 77.7
θ₂ = 77.7 + 22 = 99.7
So initial temperature before cooling ≈ 100°C . Option C.
Yes they are the power goes from one to another and if one goes off another will go off too
Answer:
L = L0 (1 + c T) where c is the coefficient and T the change in temperature
L = 50 ( 1 + 2.05E-6 * 50) = 50.0051 cm
