Question

Heat flows from an object of ____ temperature to an object of ____ temperature.

• A. higher, lower
• B. lower, higher
• C. higher, even higher
• D. lower, even lower

Answer 1

The correct option is A higher, lower

It has been experimentally observed that in absence of any external agent doing work, heat flows from an object of higher temperature to an object of lower temperature until both objects reach the same temperature.
For example - A cube of ice when held in hand, melts due to the heat it derives from the hand.
