Sam's Earth Science class is about to walk the planets. What does that mean? Well, his teacher has tied a large helium balloon outside and students will pace off the distance to each planet, using this scale as a guide. Sam's teacher has told the class to use the idea of a "pace" as a unit of measure for the activity. A pace is two steps-one with each foot. One pace is about 1 meter. The students predicted how many paces it would take to reach each planet. It takes 6 paces to reach Mercury. How many paces from the Sun is Venus?
A) 8 paces
B) 11 paces
C) 15 paces
D) 18 paces

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
