Which layer of the Sun could this image be referring to? the convection zone, because it shows how energy moves in a convection current the radiation zone, because it shows how energy is transferred through radiation the core, because it shows how the Sun creates energy through the process of nuclear fusion the chromosphere, because it shows how energy is emitted by the atmosphere of the Sun

The air that we breath is made mostly of which gaseous molecule

Marvin records scientific data about lake superior. for which property has marvin forgotten to use an si unit of measurement? shore length high temperature low temperature annual precipitation

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
