The vapor pressure of a liquid is a measure of how much vapor of a liquid sits in the air above the liquid in a closed container. So, for example, a steam room has a very high vapor pressure of water. Do you think a substance that has weaker forces between molecules would in general have a greater or lesser vapor pressure than a substance with stronger forces between the molecules? For example, compare isopropyl alcohol and water.

The of a machine determines its "usefulness." a. input force b. output force c. mechanical advantage

An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3 s 2 m ? 3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction leftward. how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction?
