What type of heat transfer when rubbing hands?
When rubbing your hands together, the primary heat transfer mechanism at play is friction. The friction generates heat by converting kinetic energy into thermal energy, warming your hands in the process.
What kind of heat transfer is warming your hands by fireplace?
The heat transfer by the fireplace warming your hands is primarily through radiation. The fireplace emits infrared radiation that is absorbed by your hands, causing them to warm up. Additionally, convection and conduction play a role as well, as the heated air around the fireplace rises and circulates, transferring heat to your hands by convection and through direct contact with the warm surface by conduction.
When a person is warming their hands by a fire what type of energy is that?
The energy transfer from the fire to the person's hands is primarily thermal energy. Heat is being transferred through conduction from the warmer fire to the cooler hands, providing warmth to the hands.
What is warming your hands in front of a fire is an example of heat transfer by?
Heat has been transferred by conduction.
As you sit by a Campfire and hold your hands to the flames they warm up you realize as you warm up that the molecules in you hands are actually moving are what?
As you warm up by the campfire, the heat causes the molecules in your hands to vibrate more rapidly. This increased molecular motion leads to the sensation of warmth that you feel. The heat energy from the fire is being transferred to your hands, causing the molecules in your skin to move faster.

Warming your hands in front of a fire is an example of heat transfer by?
ConductionConduction is heat transfer by touch. Examples include heating a pot on an electric stove and cooling red-hot metal by dipping it in liquid water. A subtler example is the use of a fan to cool off. Specifically, a layer of warmed air builds on our skin due to our body temperature. A fan pushes that layer away to be replaced with a lower temperature of air, making us feel cooler.
What does rubbing your hands together make?
Rubbing your hands together generates friction, which creates heat. This can be useful for warming up your hands on a cold day.
When you are warming your hands up over a fire What energy are you using?
Radiant energy.
When holding hands are the girls hands in the front or back?

It is a cold night around the campfire. Megan is trying to get warm by sitting close to the fire and clutching her mug of hot chocolate. How is heat being transferred to chilly Megan?
Heat is being transferred to Megan through radiation, as she is absorbing the heat energy radiating from the fire. Additionally, she is also absorbing heat through conduction by sitting close to the fire and holding the hot mug of chocolate, which is transferring heat to her hands.
What kind of heat transfer happens when you warm your hands by a fireplace?
Conduction is the primary form of heat transfer when you warm your hands by a fireplace. The heat from the fire is conducted through the solid material of the fireplace and then through your hands as you come into contact with the warm surface.
