What happens in terms of the transfer of energy as a heat when you hold a snowball in your hands?
When you hold a snowball in your hands, the heat energy produced by your hands is transferred into the fusion of ice to water. Fusion is an endothermic reaction.

What happens in terms of the tranfer of energy as heat when you hold a snowball in your hands?
Heat energy flows from the warmer (the hands in this case) to the cooler (the snowball). The flow of energy first raises the snowball's temperature (outer portion) to approximately zero degrees Celsius. Additional heat flow causes a phase change from snow (a form of ice) to water. This continues until all ice is converted. Further heat flow raises the temperature of any remaining water until it reaches skin temperature, when heat flow will cease.
What happens in terms of heat transfer when you hold a snowball in your hand?
From your hand to the ice cube as your hand is at a higher temperature than an ice cube and thermal energy flows from a higher temperature to a lower temperature.
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.
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.
Warming your hands in front of a campfire is what type of heat transfer?
Warming your hands in front of a campfire is an example of heat transfer through radiation. Heat energy is emitted from the campfire in the form of electromagnetic waves, which are absorbed by your hands, increasing their temperature.

John is riding a ski lift to the top of Wildcat Mountain. He removes his gloves and rapidly rubs his hands together to warm them up. What happens when John rubs his hands?
Rubbing his hands generates friction, which produces heat due to the conversion of kinetic energy. This process helps warm up John's hands by increasing their temperature through the transfer of energy.
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.
Give an example of energy transfer as you drink hot cocoa?
As you drink hot cocoa, the heat from the cocoa transfers to your hands and then to your body. This is an example of heat energy transfer through conduction.
What if A woman picks up a cup of hot cocoa and feels her hands get warmer. What statement best explains what is happening?
The woman is feeling her hands getting warmer due to the transfer of heat energy from the hot cocoa to her hands. This transfer of heat occurs because of the temperature difference between the hot cocoa and her hands, resulting in her hands absorbing the heat from the cocoa.
What kind of energy conversion happens when you rub your hands together?
Mechanical energy is converted into thermal energy when you rub your hands together. The friction between your hands causes them to generate heat, which warms them up.
What is the therapeutic touch?
Therapeutic touch, or TT, is a noninvasive method of healing that was derived from an ancient laying--on of hands technique. In TT, the practitioner alters the patient's energy field through an energy transfer that moves from the hands.
When you rub your hands together what kinds of energy are you making?
When you rub your hands together, you are primarily creating frictional energy. The friction between your hands generates heat energy, as the contact and movement of the surfaces create resistance and convert mechanical energy into thermal energy.
