Consider a home freezer compartment with dimensions of height 30 inches, width 60 inches, and depth 25 inches. Assume heat loss is from the five sides exposed to outside air (i. e. do not consider any heat loss through the bottom surface which the freezer sits on). For a Styrofoam insulation of thermal conductivity 0.025 W/m-K. Required:
What should be the minimum thickness of this insulation so that the total heat loss from the freezer compartment is less than 120 W?

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
