The diagram to the right shows four locations in a temperature field the temperature of each location is given in degrees Celsius heat energy will normally flow from. A) d to a B) c to b C) B to d D) b to c

Answer:
Option (B) c to b
Explanation:
The temperature of each location is given below:
Location A = 30°C
Location B = 20°C
Location C = 35°C
Location D = 29°C
Heat will always flow from a hot region to a cold region.
Considering the options given:
Option A => from D to A. This is wrong as A temperature is higher than that of D
Option B => from C to B. This is correct as C temperature is higher than that of B.
Option C => from B to D. This again is wrong as D temperature is higher than that of B.
Option D => from B to C. This is also wrong as C temperature is higher than that of B.
From the above illustration, only option B is correct as heat will naturally flow from a hot region to a cold region.
