Answer 1

Gay- lussac's law

P₂ = 1.3 atm

Step-by-step explanation:

Given data:

Initial temperature = 20°C (20+273 = 293 K)

Volume = 10 L

Initial Pressure = 1 atm

Final temperature = 100°C ( 100+273 = 373 K)

Final pressure = ?

Solution:

Gay- lussac's law state that at constant volume pressure and temperature are directly proportional to each other.

P₁/T₁ = P₂/T₂

P₂ = P₁T₂/T₁

P₂ = 1 atm . 373 K / 293 K

P₂ = 1.3 atm
