The heat from a heater is transferred through a room primarily through convection. The heater warms the air directly around it, causing it to rise and circulate throughout the room, distributing the heat. Additionally, some heat may also be transferred through radiation, where objects in the room absorb and re-emit the radiant heat.
What else can I help you with?
When the heater blows hot air around to heat your house this is an example of heat being transferred by?
The heat is being transferred by convection.
Why doesnt heat reach you when an opaque is placed in between you and a room heater?
An opaque object blocks the transmission of heat through conduction and convection, which are the main methods by which heat is transferred. Instead, the opaque object absorbs the heat and prevents it from reaching you directly. This results in reduced heat transfer and feeling less warmth from the room heater.
What are the energy changes when an electric heater is turned on?
When an electric heater is turned on, electrical energy is converted into heat energy. The electricity flows through the heating element, which has high resistance, causing it to heat up and produce heat. This heat is then transferred to the surrounding air, raising the temperature in the room.
What two energy transfers are used in the electric coil of a baseboard heater?
In an electric coil of a baseboard heater, electrical energy is first converted into heat energy through resistive heating in the coil. The heat energy is then transferred from the coil to the surrounding air through convection, which warms the room.
You can feel the heat waves from a small electric heater on your hands and face even though the heater is on the other side of the room this is an example of?
conduction. Heat from the heater is transferred to the surrounding air, which then circulates and warms up the space. Your hands and face feel the heat as they come in contact with the warm air through conduction.

What is the mode of heat transfer from a room heater?
The mode of heat transfer from a room heater is convection. This process involves the transfer of heat through the movement of fluids or gases, such as air. The heater warms the air in the room, causing it to rise and circulate, thus heating the surrounding space.
How does heater makes the whole room warm?
The heater contains a resistor. When high voltage is passed it produce a large amount of heat the blower situated in the heater blows this heat which diffuses in the room to make the room hot.
How does a ceramic heater work?
A ceramic heater works by using ceramic plates or elements inside the heater that heat up when electricity passes through them. The heat is then transferred to the surrounding air, warming up the room. The ceramic material is ideal for heating as it is quick to heat up and retains heat well.
What is the function of polished surface at the back of heating rod in a room heater?
The polished surface at the back of a heating rod in a room heater helps to reflect heat back into the room instead of allowing it to escape through the back of the heater. This increases the heating efficiency of the heater and helps to keep the room warm. This reflection of heat can also help to distribute the heat more evenly throughout the room.
How does warmth from a heater get to you?
The heater warms up the air around it, causing the air to rise. This creates a convection current, moving the warm air around the room. The warm air eventually reaches you and transfers heat to your body through conduction.
How does heat transferred through radiation?
almost everything radiates heat even people . it gets hot everyone in the room is warm blooded and all that body heat is radiating into the room .
Does a heater heat the room by radiation or by convection?
Most heaters heat a room primarily through convection. The heater warms the air, which then circulates around the room. However, some heaters also emit infrared radiation that directly heats objects and people in the room.
