you do work on the outside world when you rub your hands together to warm them? What is the efficiency of this activity?
Step-by-step solution Step 1 of 2 When rub our hands together to keep ourselves warm, heat is generated due to friction and most of these heats dissipate in our body, and very little heat goes on the outside world. Therefore, very little work is done on outside world, when rub our hand together to keep warm.
