Phase Change Materials and Insulation

The video tutorial covers a phase change engineering internship, focusing on analyzing incubator materials. It includes activities such as connecting to the Futura workspace, understanding the use of models in engineering, and testing phase change materials (PCMs) and insulating materials. Students learn to isolate variables, analyze test results, and consider the pros and cons of different materials. The lesson concludes with reading assignments and after-hours tasks to reinforce learning.

What is the first activity students need to do in the Futura workspace?

• Watch a video tutorial

• Test insulating materials

• Read and pin the daily message

• Complete a project summary

Why do engineers use models in their work?

• To avoid using technology

• To increase project costs

• To replace real-life testing

• To simplify complex processes

What is a limitation of using the Baby Warmer model?

• It is too expensive to use

• Not all babies react the same way

• It can test all materials

• It provides data on baby growth

What does plateau temperature refer to in PCM analysis?

• The duration of the test

• The cost of PCM packets

• The specific temperature of phase change

• The time it takes to reheat

What is the main goal when testing PCMs in the incubator?

• To keep the baby's temperature close to 37°C

• To test all possible materials

• To increase the cost

• To reduce the number of PCMs used

Which PCM has a high plateau temperature and low cost?

• None of the above

• PCMB

• PCMA

• PCMC

What is a pro of using wool as an insulating material?

• It slows down thermal energy transfer effectively

• It is lightweight

• It is the cheapest option

• It is easy to test

What should students do after reading chapter 4 in the dossier?

• Submit their annotations

• Complete the project summary form

• Test more PCMs

• Watch another video

Why might wool not always be the best insulating material?

• It is too expensive

• It is difficult to source

• It can make the baby too hot if PCM temperature is high

• It is not durable

What is the purpose of the project summary form?

• To finalize the project

• To test new materials

• To record early ideas about incubator designs

• To calculate costs
