What type of radiation do objects absorb and emit?
Electromagnetic
radiation
View source
What happens to an object when it absorbs radiation?
It gets
warmer
View source
What occurs when an object emits radiation?
It
cools down
View source
How does the balance of absorbing and emitting radiation affect temperature?
It
determines
the object's
temperature
View source
What happens to a hotter object like a cup of tea in terms of radiation?
It emits more radiation than it
absorbs
View source
How does an ice cube behave in terms of radiation compared to its surroundings?
It absorbs
more
energy
than it
emits
View source
What happens when an object absorbs and emits the same amount of energy?
It stays at the same
temperature
View source
What is the term used to describe the power of radiation per unit area?
Intensity
View source
What does intensity measure in terms of radiation?
Energy
transferred to a given area
View source
What does a graph of emitted radiation show on the x-axis and y-axis?
X-axis:
wavelength
; Y-axis:
intensity
View source
Which types of radiation are relevant for this topic?
Ultraviolet
,
visible light
,
infrared
View source
What would the emission curve of a room temperature object like a paper bag look like?
It emits mostly in the
infrared
range
View source
How does the emission curve change for a hotter object like burning coal?
It shifts
up
and to the
left
View source
What happens to the intensity of emitted wavelengths as temperature increases?
Intensity of all wavelengths
increases
View source
Why do bunsen burner flames change color as they get hotter?
Shorter
wavelengths
of light are emitted
View source
What type of radiation do objects at room temperature primarily emit?
Infrared
radiation
View source
How does the Earth interact with electromagnetic radiation from the sun?
It absorbs and emits
infrared
radiation
View source
What happens to the Earth's temperature during the day?
More
energy
is absorbed than emitted
View source
What occurs to the Earth's temperature at night?
Less
energy
is absorbed than emitted
View source
Why does the overall temperature of the Earth remain constant?
Some parts are always in
sunlight
View source
What are the key concepts related to the absorption and emission of radiation?
Objects absorb and emit
electromagnetic radiation
Absorbing radiation warms objects
Emitting radiation cools objects
Balance affects
temperature
Intensity
measures power per area
Emission curves shift with temperature
