Question

Сколько энергии выделится при конденсации паров эфира массой 100г, взятого при температуре 35 градусов

Answer 1

λ=384 кДж\кг- удельная теплота
100гр переводим в кг=0,1кг
384*10^3*0.1=38400Дж

Answer 2

Calculation of Energy Released during Ether Vapor Condensation

To calculate the energy released during the condensation of ether vapor, we need to use the formula:

Q = L × m

Where: - Q is the energy released during condensation - L is the latent heat of condensation - m is the mass of the ether vapor

Unfortunately, the search results provided do not directly mention the latent heat of condensation for ether. However, we can make an estimation using the latent heat of vaporization and the specific heat capacity of ether.

The specific heat capacity of ether is not provided in the search results, so we will assume it to be approximately 2.3 J/g°C based on the specific heat capacity of similar organic compounds.

Let's proceed with the calculation:

Given: - Mass of ether vapor (m) = 100 g - Initial temperature (T) = 35°C

First, we need to calculate the change in temperature (∆T) from the initial temperature to the boiling point of ether. The boiling point of ether is approximately 35°C, so ∆T = 0°C.

Next, we can calculate the energy released during condensation using the formula:

Q = L × m

Since we don't have the exact value of the latent heat of condensation for ether, we will use the latent heat of vaporization as an approximation. The latent heat of vaporization for ether is approximately 2260 J/g.

Substituting the values into the formula, we get:

Q = 2260 J/g × 100 g = 226,000 J

Therefore, approximately 226,000 J of energy will be released during the condensation of 100 g of ether vapor taken at a temperature of 35°C.

Please note that the above calculation is an estimation based on assumptions and approximations. For a more accurate value, it is recommended to consult reliable scientific sources or perform specific experiments.
