Final answer:
Without the coefficient of linear expansion for mercury, we cannot calculate the change in length of the mercury column when the temperature changes from 37.0°C to 40.0°C. Additional information is required for the computation.
Step-by-step explanation:
The question is asking to calculate the change in length of a mercury column with temperature change. To solve this problem, we would need to know the coefficient of volume expansion for mercury and use the formula ΔL = α * L0 * ΔT, where ΔL is the change in length, α is the coefficient of linear expansion, L0 is the original length, and ΔT is the change in temperature. However, in this situation, we do not have the coefficient of linear expansion for mercury provided, thus we cannot calculate ΔL directly. More information or a different approach is required to find the change in length.
