energy transfer by heating:

Question 1

what is the correlation between the temperature and the infrared radiation an object emits

Answer 1

the higher the temperature the most infrared radiation it emits, therefore the more radiation it absorbs

Question 2

what is a black body?

Answer 2

an object which absorbs all the radiation it emits, therefore doesn’t reflect or transmit radiation, it only absorbs and emits all of the radiation.

Question 3

describe in terms of infrared radiation an object at a constant temperature:

Answer 3

the object is absorbing infrared radiation at the same rate at which it is emitting radiation. an object at a constant temp also emits radiation across a continuous range of wavelengths.

Question 4

explain what happens to the black body radiation as its temperature increases (in terms of its intensity and wavelength)

Answer 4

at a lower temperature, the intensity of the black body radiation is lower overall for all wavelengths, at higher temperatures, the black body radiation is more intense and increases in intensity to the peak much faster, therefore the peak of radiation occurs in wavelengths much shorter.

the hotter the object the more short radiation that is emitted, hence causing some to glow

Question 5

what is infrared radiation?

Answer 5

electromagnetic radiation that is emitted by all objects depending on their temperature
