How does gravity help us explain the observations of patterns in space? Use your observations as
evidence to support your claim. Think about this: THERE
IS GRAVITY IN SPACE! When is the gravitational force the
strongest? What does it cause objects to do? How might
that help explain the patterns we've observed in space?

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. what is the specific heat ratio? show the math steps .

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
