Question

Object ‘A’ is at 25°C25°C and ‘B’ at 25 K when they are in thermal contact the direction of heat flow​

Answer 1

From body A to B

Explanation:

• In order to know the direction of heat flow, we need to compare the temperatures of both bodies.

• We can only compare two entities if they have the same units.

• So, we can either convert kelvin to Celcius or Celcius to kelvin.

• Here, we will convert Celcius to kelvin because it's a bit easy. We just need to add 273 to the Celcius temperature.

Converting Celcius to kelvin

• 25 + 273 = 298 K (body A)
• 25 K (body B)

Final Answer

Since, we know that the direction of flow of heat is from the hotter body to the colder. Therefore, it will be from body A to B
