question_answer Answers(1) A shirt is placed on an ironing board to be ironed. Heat from the iron is conducted to the shirt. 2. The engine of a car is turned on, and the hood becomes warm due to the conduction of heat from the engine to the hood of the car.

1 : the action or process of conveying. 2a : movement in a gas or liquid in which the warmer parts move up and the cooler parts move down convection currents.

In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath. Along with the turning of the Earth, this movement of air creates winds. Winds, in turn, create surface waves on the ocean. Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents.

Three Types of Conduction

• Electric Conduction. Electric conduction refers to the ability of a material to transfer an electric current.
• Heat Conduction. Where electric conduction refers to a transfer or electric current, heat conduction refers to a transfer of energy, specifically thermal energy.
• Photoconductivity.
• Laws Related to Conduction.

Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. The fire’s heat causes molecules in the pan to vibrate faster, making it hotter.

Conduction is one of the ways that heat can transfer from one place to another. Conduction occurs when energy is transferred from one atom or object to another. Conduction can occur in liquid, gaseous or solid objects. For conduction to take place between two objects, they must be touching each other.

1 : the act of conducting or conveying. 2a : transmission through or by means of a conductor also : the transfer of heat through matter by communication of kinetic energy from particle to particle with no net displacement of the particles — compare convection, radiation. b : conductivity.

2. Heating of metallic plate in electric iron. 3. Heating of metallic coil in iron – rod, which is used to heat the water.

Conduction is the transfer of energy in the form of heat or electricity from one atom to another within an object by direct contact. Conduction of heat occurs when molecules increase in temperature; they vibrate, and this vibration and movement passes the heat energy to the surrounding molecules.

Procedure:

1. Mix water and food coloring and pour the colored water into an ice cube tray. This experiment works best if the water is a very dark color.
2. Put the ice cube tray in the freezer until frozen solid.
3. Fill a clear glass with warm water.
4. Add one ice cube to the glass of water.
5. Observe what happens.

Cards

The temperature of the atmosphere depends on convection and indirectly the persons living in this atmosphere. The sun is a ball of plasma millions of kilometers away and its radiation, traveling through vacuum, enters the atmosphere and part of it reaches the person directly, to warm him/her.
