Question

. A copper cube measuring 1.55 cm on edge and an aluminum cube measuring 1.62 cm on edge are both heated to 55.0 °C and submerged in 100.0 mL of water at 22.3 °C. What is the final temperature of the water when equilibrium is reached? Assume a density of 0.998 g/mL for water.

Answer 1

To find the final temperature of the water when it reaches equilibrium with the heated copper and aluminum cubes, use the principle of heat transfer.

Step-by-step explanation:

To find the final temperature of the water when it reaches equilibrium with the heated copper and aluminum cubes, we can use the principle of heat transfer. The heat gained by the water is equal to the heat lost by the cubes. We can calculate the heat gained by the water using the formula Q = mcΔT, where Q is the heat gained, m is the mass of the water, c is the specific heat capacity of water, and ΔT is the temperature change. We can then set this equal to the total heat lost by the cubes and solve for the final temperature of the water.
