Question

A quantity of hydrogen is confined in a chamber of constant volume. When the chamber is immersed in a bath of meltins ice, the pressure of the gas is 1000 torr. What is the
teinperature in Celsius, when the pressure in manometer
indicates are absolute pressure of 400 torr ?​

Answer 1

Answer:

- 164 C.

Explanation:

Given :

As melting ice implies 0 C

T₁ = 273 K

P₁ = 1000 torr

T₂ = ?

P₂ = 400 toor

According to Gay Lussac's law :

P₁ / T₁ = P₂ / T₂

Putting values here we get :

1000 / 273 = 400 / T₂

= > 10 / 273 = 4 / T₂

= > T₂ = 273 × 4 / 10

= > T₂ = 27.3 × 4 K

= > T₂ = 109 K

In term of C :

= > T₂ = 109 K = - 164 C

Therefore , temperature in celsius is - 164 C.
