Heat measurements

A few weeks ago we made some A few weeks ago we made some measurements on types of insulation measurements on types of insulation

We had chosen 2 types of insulation to We had chosen 2 types of insulation to experiment with. One of them is polyester experiment with. One of them is polyester insulation and the other one is a insulation and the other one is a “Romanian” made insulation, an “Romanian” made insulation, an ecological one, made from sawdust, glue, ecological one, made from sawdust, glue, paper, water, and we covered it in paper, water, and we covered it in recycled news-papers. recycled news-papers.

The first oneThe first one

• In the first experiment we let the In the first experiment we let the “house”, made from a postal-box, not “house”, made from a postal-box, not insulated and put an electrical resistance insulated and put an electrical resistance inside. inside.

• We raised the temperature up to 60We raised the temperature up to 60˚̊C C and then we stopped the heating process and then we stopped the heating process ..

• We made a table and measured from 5 to We made a table and measured from 5 to 5 minutes during 25 minutes how much 5 minutes during 25 minutes how much the temperature had dropped .the temperature had dropped .

The second one :The second one :

• In the second experiment we In the second experiment we insulated the “house” with insulated the “house” with polyester pieces and repeated polyester pieces and repeated the heating process. And we the heating process. And we measured the cooling process measured the cooling process again from 5 to 5 minutesagain from 5 to 5 minutes

The third oneThe third one::

• In the third experiment we In the third experiment we insulated the “house” with insulated the “house” with “Romanian” made insulation, an “Romanian” made insulation, an ecological one, made from sawdust, ecological one, made from sawdust, glue, paper, water, and we covered glue, paper, water, and we covered it in recycled news-papers and it in recycled news-papers and repeated the heating process. And repeated the heating process. And we measured the cooling process we measured the cooling process again from 5 to 5 minutesagain from 5 to 5 minutes
