Practice B
Name_______________________________
1. If an elephant gives you 200 L of ammonia gas at STP and heats it up to 200oC and force
it into a container with a pressure of 2.8 atm what would the new volume be? (The
elephant REALLY needs to know!)
2. The cutest puppy in the world would like you to find out how much pressure it can
handle before it implodes down under the sea. She right now is at 780 mmHg and 1233
mL of space inside her when it is 30 degrees Celsius out. She knows that she will
implode when her internal volume becomes .234L at temperature of 190K. What
pressure would you need to stay below to keep her alive? If you screw up many people
will cry…
3. Tommy the turtle is trying to test the strength of his shell by diving deep in the ocean.
He has a volume of .75L at the surface where it is 40 oC and starts diving until he is at a
place where his volume would be .21L and the temperature would be 79oF. That is all
the farther he can go. How much pressure can his shell handle?
