On the absolute scale of temperature (in Kelvin), the zero of the scale corresponds to
the mean temperature of space
the melting point of ice
the freezing point of hydrogen
the freezing point of nitrogen
the temperature at which motions of atoms and molecules essentially cease

Our Sun has a surface temperature of about 5,800 K and a dominant wavelength of emission at about
What is the approximate dominant wavelength of emission for a star whose surface
temperature is 11,600 K?
Most of the mass of the solar system is made up of atoms or molecules of
a) carbon, oxygen and nitrogen

A piece of iron is heated from room temperature
C = 300K to red hot at 627
C = 900K. By what
factor will the total energy per second emitted by this iron increase?
An astronomer photographs the spectrum of an object and finds a spectral line at 499 nm wavelength.
the laboratory, this spectral line occurs at 500 nm.
According to the Doppler effect, this object
is moving toward the Earth at 1/500 the speed of light
is moving toward the Earth at 499/500 the speed of light
is moving away from the Earth at 1/500 the speed of light
is moving away from the Earth at 499/500 the speed of light
