P1/T1 = P2/T2

125⁰C = 398.15 k

182⁰C = 455.15 k

1.22/398.15 = p2/455.15


p2= 1.39atm

the pressure of the gas be after the temperature change is 1.39 atm

Answer:

1.4 atm

Explanation:

According to Gay Lussac’s law, the pressure of gas is inversely proportional t its temperature, when the volume is constant

Initial temperature = 125 + 273 = 398 K

Final temperature = 182 + 273 = 455 K

Initial pressure = 1.22 atm

\frac{P1}{T1} = \frac{P2}{T2}

1.22 atm / 398 K = P₂/ 455 K

P₂ = \frac{1.22 atm x 455 K}{398 K} = 1.4 atm

Irina18 [472]

Explanation:

A process in which water vapor changes into liquid state is known as condensation. As we know that when energy is released in a reaction then it is known as exothermic reaction and when energy is absorbed in a reaction then it is known as endothermic reaction.

As vapors have high energy so, when they change into liquid state then heat energy is released by them. Therefore, condensation is an exothermic reaction.

As per Le Chatelier's principle, any disturbance caused in an equilibrium reaction will tend to shift the equilibrium in a direction away from the disturbance.

So, when there will occur a decrease in temperature then molecules of a gas will come closer to each other. Hence, there will also occur a decrease in vapor pressure of the gas.

Reil [10]
The heat transfer formula is;
Q = m * c * Δ T >>>> (1)
where, Q is the heat transfer
m = mass  (gram)
c = the specific heat capacity (J/g)
Δ T = change in temperature
∵ we have one mole of Ethanol
∴ the weight of ethanol equals its molecular weight = (2*12)+(6*1)+(16) = 46 g
we will assume that the specific heat capacity of ethanol is 2.46 J/g (from google) 
ΔT = 25 - 320 = - 295 C
By substitution in (1)
∴ Q = 2.46 * 46 * (-295) = - 33382.2 J
