Work, Energy and Momentum Notes
... When the weather gets cold, the air we breathe in is heated when it comes in contact with warm lung tissue. The energy to heat the air comes from our body. The inhaled air warms to nearly the temperature of the interior of a human body 37 oC. When humans exhale, some heat is retained by the body, bu ...

Epoxies and Glass Transition Temperature
... As a material moves through the glass transition temperature range, its CTE increases dramatically — ultimately becoming three to five times higher than its value below the Tg range. After the epoxy passes through the glass transition temperature range, its material properties are significantly diff ...
