Question

Цинкове та мідне тіла однакового об’єму, нагріти до однакової температури, занурили в ємності з однаковою кількістю холодної води. В якій ємності вода нагріється більше і чому? 

Answer 1

Heating Zinc and Copper Bodies in Equal Volumes

When heating zinc and copper bodies of equal volume to the same temperature and then immersing them in containers with an equal amount of cold water, the water in which metal will heat up more depends on their specific heat capacities.

Specific Heat Capacity: - The specific heat capacity of a substance is the amount of heat required to raise the temperature of one gram of the substance by one degree Celsius. - The specific heat capacity of zinc is 0.387 J/g°C, while the specific heat capacity of copper is 0.385 J/g°C [[1]].

Explanation

Copper: - Copper has a lower specific heat capacity compared to zinc, which means it requires less heat to raise its temperature by one degree Celsius. - Due to its lower specific heat capacity, copper will transfer more heat to the water compared to zinc when both are immersed in the same amount of cold water. - As a result, the water in which the copper is immersed will heat up more than the water in which the zinc is immersed.

Conclusion: - Therefore, the water in the container with the copper body will heat up more than the water in the container with the zinc body due to the difference in their specific heat capacities.
