2. When you are a passenger in a car that makes a tight turn, your body seems to respond to the turn by moving towards the side of the car on the outside of the turn. Is a force acting on you that pushes you towards the outside of the curve? Explain. Consider the message of Newton's First Law in your answer.
3. In the situation described in #2, if your body stays relaxed as the vehicle you are in turns to the left, you will eventually contact the right-hand window and feel "pushed" against it. Are you being pushed against the window, or is the window pushing on you? Explain. Consider Newton's second law.
What is the freezing point of this solution? The Kf for water is 1.86 C/m and the density of ethylese glycol is 1.1135 g/mL. Consider if the solute is an electrolyte or a non electrolyte.
