Express your answer to two significant figures and include the appropriate units.

Answer 1

To find the entropy change of the aluminum and copper, we can use the formula ΔS = mcΔT, where ΔS is the change in entropy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. To find the entropy change of the universe, we can add up the entropy changes of the aluminum and copper.

Step-by-step explanation:

To find the entropy change of the aluminum, we can use the formula:

ΔS = mcΔT

where ΔS is the change in entropy, m is the mass of the aluminum, c is the specific heat capacity of aluminum, and ΔT is the change in temperature.

For the copper, we can use the same formula:

ΔS = mcΔT

where now m is the mass of copper and c is the specific heat capacity of copper.

Finally, to find the entropy change of the universe, we can add up the entropy changes of the aluminum and copper:

ΔSuniverse = ΔSaluminum + ΔScopper
