you can feel it from convection. (heater on ground)
you can feel it from conduction. (spoon in soup)
you can feel it from radiation. (light)

Is the heat transferred from a hot zinc roof to a person below it a good example of heat transfer by radiation Explain?
Yes - this should be a good example of heat transfer by radiation. It is unlikely you will transfer heat by natural convection since the roof is above the person and any heated air will rise to the roof rather than sink from the roof down to the person. Air is a rather poor conductor of heat so any heat transfer by conduction from the roof down to the person will be very slow. In contrast to this, the tin roof, if hot enough will be a fairly good heat radiator - enough that it could be sensed by a person below, i.e. they will feel the radiant heat transfer.
Why isn't the Radiator not getting hot?
THAT MEANS THE RADIATOR IS GETTING HOT, Probably you mean Why isn't the radiator getting hot. could be becaused the thermostat isn't opening or the house to the radiator is disconnected or there is no coolant in the radiator,
What are some synonyms for conduction?
I suppose that it could be transfer, but not each transfer is conduction
Explain how convection could be used to heat a room with a hot radiator on one side of the room?
Hot air rises to the ceiling and as it cools on the far side of the ceiling it sinks back down to the floor on the opposite side of the room from the radiator. It will not evenly heat the room. To get the best comfort level, you need a ceiling fan to push the hot air to the floor. The hot radiator sets up convection currents that transfer thermal energy to the rest of the room and eventually heat the entire room. How do convection currents work? The hot radiator warms the air that is closest to the radiator. The warm air expands, becomes less dense and rises to the top of the room. When the air reaches the top of the room it is pushed sideways towards the far wall by the more recently warmed air rising from the radiator below. In this way warm air moves to the other side of the room. Once on the other side of the room the air drops down both because it has cooled a little and because the air behind it continues to push on it. The air then continues to circulate back to the radiator and repeat the process.
Why doesn't the radiator of a car pull the water back from the reservoir even if the radiator cap is new?
It sounds like there's a leak somewhere. If it's not in the cap, it could be in the hose, or the connection, or the radiator itself. If you can't figure this out on your own, take it to a mechanic.
Could you please give the fourth method of heat transfer?
Fourth method of heat transfer is via evaporation.
Explain the triangle trade?
There are many ways in which you could explain the triangle trading method. You have three points of trade that cycle.

Method to count the number of bacteria in a sample of water?
explain how using a lot of disinfectant to clean toilets could have an effect on sewage treatment
How do you change the antifreeze?
I have a 91 Ford escort that has two caps. one is on the radiator itself and one next to it that says coolant only. how do I know where the antifreeze goes? does a mixture of coolant and water go in the radiator or does only water go in radiator and coolant in the other one? I have never seen an engine with this. could you help explain it?
Your BMW 520 is overheating what could it be?
Waterpump, thermostat, radiator, radiator hoses.

How do you make radiator fan turn on?
There are a few ways you could make your radiator fan turn on. You could fix the wiring for example.
1999 Dodge Intrepid overheats when going uphill only in the heat of day at night its fine?
you could be low on antifreeze, could be a plugged radiator, or the radiator could be dirty. I had the same problem with my Dodge Ram and it was a plugged radiator
Are radiators correctly named?
Typically, radiators transfer heat to their environment by both radiation of infrared wavelengths and convection via air (or water, if the radiator is immersed in water). How much IR radiation versus how much convective transfer depends on the specifics. For a very general answer, radiator is a simple, useful name. It is hard to see what changing it would accomplish. In electronics, things which dump heat from components to environment are called heat sinks. This is not really an improvement. A "radiator" in a room could be called "heater". Any other ideas out there.
