does rubbing your hands together in space make them warm? like if there is no air in a room will friction between your hands generate heat?
Friction in vacuum refers to the resistance or force that occurs between two surfaces in a vacuum environment. It is caused by the microscopic irregularities on the surfaces that come into contact with each other.
Yes, friction can occur in a vacuum. Although there is no air or other medium present, the surfaces in contact still have irregularities that can cause resistance and generate heat.
When you rub your hands together, the microscopic irregularities on the surfaces come into contact and start to rub against each other. This generates heat due to the friction between the surfaces.
No, the amount of heat generated by rubbing hands in a vacuum is different from that generated in air. In a vacuum, there is no air to dissipate the heat, so it can build up and cause a significant increase in temperature between the two surfaces.
Friction in vacuum is used in various scientific experiments to study the effects of friction on different materials in a controlled environment. It is also used to simulate the conditions in space, where there is no air resistance and objects experience a different type of friction compared to Earth's atmosphere.
