Answer:
-178.8 K
Explanation:
From Charles law,
V₁/T₁ = V₂/T₂.................... Equation 1
Where V₁ = Initial volume, T₁ = Initial Temperature, V₂ = Final volume, T₂ = Final Temperature.
Making T₂ the subject of the equation
T₂ = V₂T₁/V₁............... Equation 2
Given: V₂ = 1.00 L, V₁ = 2.5 L, T₁ = 298 K.
Substitute into equation 2
T₂ = 1.00(298)/2.5
T₂ = 119.2 K.
But,
Change in temperature = T₂ - T₁ = 119.2-298
Change in temperature = -178.8 K.
Hence the change in temperature = -178.8 K
