Question

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

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

Answer 1

The correct option is A higher, lower

It has been experimentally noticed that in absence of any external agent doing work then 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 is placed into the hand of a man. Over time, heat conducted from the man’s hand to the ice cube will cause the ice to melt.
