Answer:
232.9K
Explanation:
V₁ = 5dm³
P₁ = 0.92atm
T₂ = 30°C
V₂ = 5.7L
P₂ = 800mmHg
Unknown:
T₁ = ?
Solution:
To solve this problem, we are going to apply the combined gas law which is fusion of the avogadro's law, boyle's law and charles's law.
Mathematically;
p, v and T are pressure, volume and temperature respetively
1 and 2 depicts the initial and final states.
We need to convert ;
temperature to K and pressure into atm
T₂ = 30°C = 273 + 30 = 303K
P₂ = 800mmHg;
760mmHg = 1 atm
800mmHg = = 1.05atm
Input the variables and solve;
T = 232.9K
