What is the entropy change of [m] g of water when it changes from  liquid to steam at its usual boiling point ?LV = 2.26 MJ/kg.

This study tool with pull 30 random questions per each attempt. You can utilize this tool to prepare for the final exam. Please do not copy/paste, screen record, print, or otherwise manipulate this resource. This practice exam should only be used for exam preparation inside of Blackboard. You can take the exam as many times as you wish. You will receive a new question set each time you take the exam. This is an ungraded activity.

You are making a circular turn in your car on a horizontal road when you hit a big patch of ice, causing the force of friction between the tires and the road to become zero. While the car is on the ice, it

A block of mass  m sits at rest on a rough inclined ramp that makes an angle  θ with the horizontal. What must be true about normal force  F on the block due to the ramp?

What is the centripetal acceleration of a point on the perimeter of a bicycle wheel of diameter 80 cm when the bike is moving 8.0 m/s?

A car goes around a circular curve on a horizontal road at constant speed. What is the direction of the friction force on the car due to the road?

There will be 24 questions on the Exam.  Each question is worth 1-3 points; most are 2 points.  The questions will be divided into 3 pages. Each page will have 6-10 questions.  You WILL be able to go back and forth between the pages as much as you want.  Anne will provide a periodic table (from the Course Workbook) and pH color guide and on each page.  You are NOT allowed to use a phone or a graphing calculator on the exam. If you print out the periodic table that Anne provides (in Content > Study and also in the Printed Project), it must NOT have anything written on it AND you must hold it up (front & back) during the room scan, along with any blank paper for working out calculations.  Which statement is CORRECT? 

Sue and Sean are having a tug-of-war by pulling on opposite ends of a 5.0-kg rope. Sue pulls with a 15-N force. What is Sean’s force if the rope accelerates toward Sean at 3.0 m/s2?
