Why can you feel the heat from fire when sat near it.?
You can feel the heat from fire when sitting near it because heat is transferred through radiation, conduction, and convection. The infrared radiation from the fire warms your skin and surrounding air. This sensation is what makes you feel the heat.
Explain how you could feel heat from a radiator by more than one method of transfer?
You can feel heat from a radiator through conduction, where direct contact with the hot radiator causes heat to transfer from the radiator to your body. You can also feel heat through convection, where the hot air near the radiator rises, creating a current that carries heat to you.
Why is it cooler on the floor than in the bed?
Heat rises, so the air near the ceiling tends to be warmer while the air near the floor is cooler. This is why you may feel cooler when closer to the floor. Additionally, the bed may trap heat from your body, making it feel warmer compared to the floor.
Why if your hand is held near to the side of a flame does the front of your hand feel heat?
The heat from the flame travels through the air as infrared radiation and warms the front of your hand that is nearby. The closer your hand is to the flame, the more heat it will feel due to the transfer of thermal energy.
Is it true that infrared radiation cannot be seen but it can be felt as heat?
Yes, that is correct. Infrared radiation has wavelengths longer than visible light, making it invisible to the human eye. However, our skin can detect infrared radiation as heat, which is why we can feel it when we stand near sources of infrared radiation, such as a fire or a heater.
Why do you feel hot when you stand near the fire?
Cause heat could be transfered through thin air - it's called radiation.
Why can you feel the heat from fire when sat near it.?

How might each reaction feel if you were to put your hands near it?
An exothermic reaction would feel warm or hot if you put your hands near it, as it releases heat to its surroundings. An endothermic reaction would feel cool or cold if you put your hands near it, as it absorbs heat from its surroundings.
What cause you to get warm if you stand near a fire?
the heat from the fire! what kind of question is that?

Why does a clothes dryer require a 220 volt outlet while a toaster only requires a 110 volt outlet?
Because a toaster does not pull near the current that a cloths dryer does.

Can you explain why you feel warm when you are standing away from a campfire?
A fire burns fuel to produce heat and gasses. Some of the heat comes off as visible light and some warms the air in and around the fire and this rises with the smoke.However, allot of the heat comes off as infra red radiation - a form of light that you can not see with your eyes, but that you can feel with your skin (as the warmth from the fire).Your skin is always trading heat with its surroundings, your body is always losing heat at a moderate rate to the air touching it. When more heat comes in than goes out, the skin feels warm. So the side of you that faces a fire will feel hot because it is getting more heat than it is losing (because it is absorbing the infra red radiation), while your back surface is shaded from the fire's energy (by your front) and this will be losing more heat than it is receiving and will therefore feel cold.

The heat from the flame travels through the air as infrared radiation and warms the front of your hand that is nearby. The closer your hand is to the flame, the more heat it will feel due to the transfer of thermal energy.
Can go near heat 3 weeks after you have a baby?
Near heat? You can go near anything you could go near, or could not, before you were pregnant.
