When you sit in front of an open fire what means of transfer makes you warm Brainly?

Convection is the process of transferring of heat by the bulk movement of molecules which are in the fluids like the liquid and gas. Thus a person gets heated while sitting near a fire.

When you sit in front of an open fire you are warmed mostly by?

Heat
Heat moves through space as energy waves. It is the type of heat one feels when sitting in front of a fireplace or around a campfire. It travels in straight lines at the speed of light. This is the reason that when facing the fire, only the front is warmed.

When you are sitting by a campfire the heat you feel on your body is due to which of the following?

thermal radiation
When you sit by a campfire, most of the heat you are receiving from the fire does not come from hot air. It comes from thermal radiation.

In what way is heat being transferred in a bedroom?

Radiation is responsible for most of the heat transferred into the room. Heat transfer also occurs through conduction into the room, but at a much slower rate. Heat transfer by convection also occurs through cold air entering the room around windows and hot air leaving the room by rising up the chimney.

What does conduction mean in a fire?

Conduction: This type of heat transfer occurs inside materials, typically solid materials. The heat from the fire is passed from molecule to molecule along the length of the material. The fire will generally follow the heat or sometimes the heat from conduction may cause a new fire to ignite elsewhere.

Who you stand near a fire you feel hot Why?

you feel hot because, when you stand near a fire the temperature around you is greater than your body temperature leading to an exchange of heat, your body then gain heat from the fire i.e an endothermic reaction occurs and the heat absorbs leads to an increase in your body temperature making you to feel hot.!

When you sit facing a campfire outdoors your face feels quite warm because?

Which of the 2 has the hotter surface temperature? When you sit facing a campfire outdoors, your face feels quite warm because? The campfire is radiating toward your skin. People fighting forest fires carry emergency tents that have shiny aluminum outer surfaces.

How does a person sit by a campfire and get heat?

The campfire is emitting heat through all three modes. Since air is a poor thermal conductor, you won’t receive much heat from the campfire via conduction unless you stick your hand in the fire. Therefore, assuming you are sitting several feet away from the campfire, we can ignore conductive heat transfer.

How is heat transferred from one fire to another?

A fire spreads by transferring heat energy in three ways: Radiation, Convection, and Conduction. Radiation refers to the emission of energy in rays or waves. Heat moves through space as energy waves.

Why does the side facing the fire get hot?

This is why the side of your body facing the fire gets hot while the side facing away from the fire stays cold. Thermal radiation is a form of light, and light travels out in straight lines. The side of your body facing away from the fire is literally in shadow and cannot receive the thermal radiation.

What kind of heat transfer does a camping fire use?

The more dense a material, the more heat it can carry from one location to another. In a camping fire conduction serves to transfer heat through the ground from where the fire is located, spreading out in a gradual, spherical pattern.
