Answer to Question #266562 in General Chemistry for Micheal

Question

This diagram shows two closed, insulated compartments, where no energy can escape. Both compartments contain water of equal volume but varying temperatures of 50°C and 25°C respectively.

If the temperature of the water measuring 50°C decreased by 5°C, the temperature of the water measuring 25°C would

A. remain the same.

B. also decrease by approximately 5°C.

C. increase by approximately 5°C.

D. none of the above

Answer 1

Given that the two compartments are insulated but there is a metal divider between them as shown in the figure. This would allow transfer of heat between the compartments to the point when the temperatures are in equilibrium.

If 5 ° decreased from 50 °C compartment I has 45 °C and compartment II has 25 °C

Equilibrium will be at $\frac{45+25}{2} = 35 \; °C$

Hence an increase of 10 °C in the II compartment.

So, answer D Non of the above.
