Yes, infrared radiation can detect heat. Infrared sensors are designed to detect and measure the infrared radiation emitted by objects, including heat emitted by living organisms or warm objects.
Radiant heat I assume you mean the heat emitted by the Sun rather than the heat of the Sun itself.

-- The resistance of the wire.AND-- The voltage between the ends of the wire.OR-- The current through the wire.
Not at all. First of all, 200 Celsius is not double 100 Celsius. To make this kind of comparisons, you have to use an absolute scale, i.e., Kelvin. 200 Celsius = 473K; 100 Celsius = 373K, so that is only about a 27% increase. Second, the energy emitted by a hot body is (roughly?) proportional to the 4th. power of the temperature. Raising the ratio to the fourth power gives you a factor of about 2.59 - the hotter body will radiate 2.59 times as much heat energy as the cooler body.
Depending on the heat emitted by a body, the colour of the body varies. by mapping the colour of a body to the standard scales, the temperature of the body can be determined. The temperature of sun is determined in this manner.

Generally, it depends on sweat.
the excretory system ----------------------------------------------------------------------------------------------------------- The human body depends on it's unique sweat glands to cool off the body. Heat containing sweat is released from the glands, in which the atmosphere absorbs the heat, resulting in a loss of heat for the body.

No. It is a nuclear change.

The body channels blood to neat the surface of the skin in order to facilitate heat exchange with the air. The body also sweats as the water on the skin helps get rid of heat.
The heat and light emitted from the sun comes from the nuclear reactions that occur on it.
