remains constant?

Answer:

Explanation:

This is a Charles Law problem => V ∝ T => direct proportionality ... that is, increasing temperature => increasing volume and decreasing temperature => decreasing volume. The empirical relationship comparing two sets of conditions is V₁/T₁ = V₂/T₂.

Given

V₁ = 462 ml         T₁ = 27°C = 300K

V₂ =  ?                  T₂ = 37°C = 310K

V₂ = V₁(T₂/T₁) = 462ml(310K/300K) = 477ml (3 sig. figs.)
