A certain gas at 2oC and 1.00 atm pressure fills a 4.0 container. What volume will the gas occupy at 100oC and 780 torr pressure

artcher [175]

The final volume V₂=4.962 L

<h3>Further explanation</h3>

Given

T₁=20 + 273 = 293 K

P₁= 1 atm

V₁ = 4 L

T₂=100+273 = 373 K

P₂=780 torr=1,02632 atm

Required

The final volume

Solution

Combined gas law :

P₁V₁/T₁=P₂V₂/T₂

Input the value :

V₂=(P₁V₁T₂)/(P₂T₁)

V₂=(1 x 4 x 373)/(1.02632 x 293)

V₂=4.962 L

Show the calculation of the energy involved in condensation of 150 grams of steam at 100oC if the Heat of Vaporization for water

vaieri [72.5K]

Answer : The energy involved in condensation is, 339 kJ

Explanation :

Formula used :

$q=m\times L$

where,

q = heat required = ?

L = latent heat of vaporization of water = $2.26kJ/g$

m = mass of water = 150 g

Now put all the given values in the above formula, we get:

$q=(150g)\times (2.26kJ/g)$

$q=339kJ$

Therefore, the energy involved in condensation is, 339 kJ
