Answer 1

Answer:

a) heat flows from HEIGHER temperature to LOWER temperature.

B). Insulation in houses increases R-value and the resistance to heat flow.

C) During winters we must wear MANY LAYER Of thick clothing to keep us warm

If you have a confusion in my answer of (C) part then lemme tell u why it's bcz if we wear only one layer it may keep us a little warm but wearing more thick layers can keep us even more warm in winters :)

Hope it helps ⭐
