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

Answer 1

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

 

Удельная теплота парообразования/конденсации эфира λ=384 кДж\кг

при температуре 35 35 градусов цельсия

масса эфира m=100 г=0.1 кг

Кол-во тепла при конденсации эфира  Q1= λ m= 384*10^3 *0.1 =38400 Дж = 38.4 кДж

 

Ответ =38400 Дж = 38.4 кДж

Answer 2

Calculating the Energy Released from the Condensation of Ether Vapor

To calculate the energy released from the condensation of ether vapor, we can use the formula:

Q = m * L

Where: - Q is the energy released - m is the mass of the substance (in this case, ether) undergoing the phase change - L is the latent heat of vaporization

Given Data

- Mass of ether (m) = 100 g - Temperature of ether = 35 degrees Celsius

Latent Heat of Vaporization

The latent heat of vaporization for ether is required to calculate the energy released during condensation. Let's find the latent heat of vaporization for ether.

According to source the latent heat of vaporization for ether is 27 J/g.

Calculation

Using the given mass of ether (100 g) and the latent heat of vaporization (27 J/g), we can calculate the energy released during the condensation of ether vapor.

Q = m * L Q = 100 g * 27 J/g Q = 2700 J

Therefore, the energy released during the condensation of 100 g of ether vapor at 35 degrees Celsius is 2700 joules.

This calculation is based on the provided data and the latent heat of vaporization for ether from source
