Answer to Question #335800 in Chemistry for shimmy

Question

1.  If 15.0 L Neon at 60 0C is heated at constant pressure, what temperature will it have if it occupies a volume of 4.50 L?

Answer 1

Given:

V₁ = 15.0 L

T₁ = 60°C + 273.15 = 333.15 K

P₁ = P₂ = constant

V₂ = 4.50 L

T₂ = ???

Solution:

Since the pressure and amount of gas remain unchanged, Charles's law can be used.

Charles's law can be expressed as: V₁ / T₁ = V₂ / T₂

V₁T₂ = V₂T₁

To find the temperture, solve the equation for T₂:

T₂ = V₂T₁ / V₁

T₂ = (4.50 L × 333.15 K) / (15.0 L) = 99.945 K = 100 K

T₂ = 100 K or −173°C

Answer: at 100 K
