Two kilograms of saturated water mixture at 200◦C, x = 0.5 is heated in a constant-pressure process to 300◦C in a piston-cylinder arrangement.

1. Find the initial and final volumes and the total heat transfer required.

2. Track the process in steps of jumps of 5% in the quality, after that use steps of 10◦C until final state

is reached. Plot the relationship between the heat transfer vs the volume and the work done vs

the volume.

Galileo was the first to notice that the moon has craters, valleys, and mountains. how might this have changed people's perception of the moon at the time?

How does the kinetic energy of a charge change as the charge moves under the effect of an electric field from higher potential to lower potential? a.the kinetic energy increases.b.the kinetic energy decreases.c.the kinetic energy remains the same.d.the kinetic energy is always zero.

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
