What else can I help you with?
When you walk bearfoot across a hot sidewalk you feel heat on your feet. explain What is happening with the molecules in both the sidewalk and your feet and in which direction thermal energy is moving?
As you walk barefoot on a hot sidewalk, the sidewalk molecules vibrate more due to the heat, transferring thermal energy to your feet. The heat is moving from the sidewalk (higher temperature) to your feet (lower temperature), causing your feet to feel hot. The increased molecular vibrations in the sidewalk result in the sensation of heat on your feet as thermal energy is transferred.
How is heat transferred to sidewalks?
Heat is transferred to sidewalks through conduction, where energy is transferred from the hot surface of the sidewalk to the cooler ground beneath it. Sunlight is absorbed by the sidewalk, heating it up, and then the heat is transferred to the sidewalk material and to the ground underneath.
What is the energy transferred by heat from the sidewalk to your foot called?
Radiation
How is heat from hot sand transferred to your feet?
Heat from hot sand is transferred to your feet through a process called conduction. The sand particles come into direct contact with your feet, and as they vibrate due to their increased temperature, they transfer their thermal energy to your feet, making them feel hot.
Is cooking an egg on a hot sidewalk a principle of conduction?
Yes, cooking an egg on a hot sidewalk is an example of conduction. The heat from the sidewalk is transferred to the egg through direct contact, causing the egg to cook.
How is the heat transferred to your feet from the street?
Conduction.
What is the process by which heat is transferred through a vacuum by electromagnetic waves?
The process by which heat is transferred through a vacuum by electromagnetic waves is called radiation.
Side walk is warmed by the heat of the sun physical or chemical?
The sidewalk being warmed by the heat of the sun is a physical process. The sun's rays transfer heat energy to the sidewalk through radiation, causing the molecules in the sidewalk to vibrate more rapidly and increase in temperature. This is a physical change as no new substances are being formed in this process.
When you walk on a hot surface heat is transferred to your feet by what?
Heat is transferred to your feet through conduction, which is the direct transfer of heat by physical contact between two objects at different temperatures. In this case, the hot surface transfers its heat energy to your feet when they come in contact with each other.
What is the process of heat transferred in the troposphere called?
convection currents
Heat can be transferred through a liquid by a process called?
Convection
How can heat be transferred through matter by the collisions of atoms or through space?
Heat can be transferred through matter by the collisions of atoms through a process called conduction. In this process, heat energy is transferred from one particle to another. Additionally, heat can be transferred through space by electromagnetic waves in a process known as radiation. In this case, heat energy is transferred through empty space without the need for a medium.
