Natural materials like stone and bricks are not good insulation materials. - ANS
✔✔T
When you insulate the attic of a home the R-value of insulation increases at the
same rate as its thickness. - ANS ✔✔T
A heat mover speeds up a natural heating process. - ANS ✔✔F
Heat in a room from an air register moves from warmer areas to cooler areas of
the room due to _____. - ANS ✔✔Convection
