Question

N this lesson, you learned how to distinguish physical

changes from chemical changes. You also discovered how
specific chemical changes can be observed and even
controlled by paying attention to energy and other evidence.
Apply Scientific Reasoning What are some general rules
or patterns you learned about in this lesson that you can apply
when designing a device that will release or absorb heat?

Answer 1

When designing a device to release or absorb heat, consider the energy transfer, thermal conductivity, and heat capacity.

Step-by-step explanation:

When designing a device that will release or absorb heat, there are several general rules or patterns that can be applied.

• Energy transfer: It is important to consider the energy changes involved in the process. For example, when designing a heater, the device should be able to convert electrical energy into heat energy.
• Thermal conductivity: The materials used in the device should have high thermal conductivity to efficiently transfer heat. For instance, a device that absorbs heat may use materials like copper or aluminum for better heat transfer.
• Heat capacity: The device should have a sufficient heat capacity to store and release the desired amount of heat. This can be achieved by using substances with high heat capacity, such as water or certain metals.
