A windowpane is half a centimeter thick and has an area of 1.0 m2. The temperature difference between the inside and outside sur
1 answer:
To tackle this problem, one must utilize the ideas related to the rate of heat flux defined in energetic terms. The heat transfer rate signifies the quantity of heat moved per time unit through a specific material. This can be calculated mathematically in the following manner:
Where
k = 0.84 J/s⋅m⋅°C (This is the thermal conductivity of the substance)
Area
Length
= Temperature of the "hot" reservoir
= Temperature of the "cold" reservoir
Substituting our specific values provides us with,
Thus, the accurate option is B.
