Introduction to Chemistry with Lab test
Question 3 of 12 4.0/ 4.0 Points `We've all blown up balloons. When you blow into a balloon, you are putting in more moles of gas. Let's say that on the second exhalation (blow) you blow in the exact same number of moles as you did with the first exhalation. So, you doubled the number of moles in the balloon. If the temperature and pressure remained constant, what is true about the volume of the gas in the balloon? A.The volume increases, but more information is needed. B.The volume is halved. C.The volume decreases, but more information is needed. D.The volume doubles. E.none of the above Answer Key: D Feedback: Good. Avogadro's law is in 11.7 Question 4 of 12 4.0/ 4.0 Points `I have a cylinder sitting in my lab that contains 0.500 L of 25.85 C gas, and it's pressure is 14.7 psi. If I push the cylinder and increase the pressure to 22.6 psi and the temperature to 59.85 C, what will be the new volume of the gas in L?A.2.77 L B.0.691 L C.0.362 L D.1.45 L Answer Key: C Feedback: Good. Combined gas law is discussed in 11.6
