When two bodies A and B are brought in contact with each other, heat does not flow between them. When another body C is brought in contact with B, the heat starts flowing from C to B. After the heat flow stops, C is now brought into contact with A, then which of the following is correct?
When two bodies A and B are brought in contact with each other, heat does not flow between them. When another body C is brought in contact with B, the heat starts flowing from C to B. After the heat flow stops, C is now brought into contact with A, then which of the following is correct?
The correct option is C Heat flows from C to A.
We know that heat flows from a higher temperature to a lower temperature.
When A and B are brought together, there is no heat flow between them. It means that A and B are in thermal equilibrium.
Now when another body C is brought in contact with B, heat flows from C to B. This means C is at a higher temperature than B. Heat flows till the temperatures of B and C are equal. There will be a rise in temperature of B and temperature of C will be reduced till they reach the same temperature. Thus, B and C will have a temperature higher than that of A.
Now when C is brought into contact with A, since C has a higher temperature than A, there will be heat flow from C to A.
Heat flows from C to A.
We know that heat flows from a higher temperature to a lower temperature.
When A and B are brought together, there is no heat flow between them. It means that A and B are in thermal equilibrium.
Now when another body C is brought in contact with B, heat flows from C to B. This means C is at a higher temperature than B. Heat flows till the temperatures of B and C are equal. There will be a rise in temperature of B and temperature of C will be reduced till they reach the same temperature. Thus, B and C will have a temperature higher than that of A.
Now when C is brought into contact with A, since C has a higher temperature than A, there will be heat flow from C to A.
