A bowling ball is traveling at 3 m/s. It starts to roll up a ramp. How high above the ground will the ball be when it stops roll
ing? Neglect friction and assume the ramp is plenty long enough to do this. (For this problem your initial kinetic energy can be set equal to your final potential energy. 1/2mv2 = mgh).
The amount of energy to reach the boiling point is . To pass the boiling point, are necessary (18.02 is the molar mass of water). This means that are left. This allows the steam to heat another . Therefore, it ends as steam at temperature
