Given:
Ti = 44.0 oC
= (44.0+273) K
= 317 K
Vi = 1.72 L
Vf = 1.18 L
use:
Vi/Ti = Vf/Tf
1.72 L / 317.0 K = 1.18 L / Tf
Tf = 217 K
Tf = (217-273) oC
Tf = -56 oC
Answer: -56 oC

A cylinder with a moveable piston contains 0.594 mol of gas and has a volume of 240 mL. What will its volume be if an additional 0.174 mol of gas is added to the cylinder? (Assume constant temperature and pressure.)
A cylinder with a moveable piston contains 0.581 mol of gas and has a volume of 280 mL. What will its volume be if an additional 0.158 mol of gas is added to the cylinder? (Assume constant temperature and pressure.)
A 2.92-L gas sample in a cylinder with a freely moveable piston is initially at 23.0 ∘C. What is the volume of the gas when it is heated to 133 ∘C (at constant pressure)?
4. -14 points SerCP11 10.4.OP.031. My Notes Ask Your Teacher (a) A tank contains one mole of nitrogen gas at a pressure of 6.75 atm and a temperature of 26.0°C. The tank (which has a fixed volume) is heated until the pressure inside triples. What is the final temperature of the gas? °C (b) A cylinder with a moveable piston contains one mole of nitrogen, again at a pressure of 6.75 atm and a temperature of 26.0°C. Now, the cylinder...
questions 4 and 5 please explain 4. A cylinder with a piston originally contains 5.0 L of He gas at a temperature of 310 K. When the gas is cooled the piston moves and the new volume is 2.4 L. What is the final temperature of the gas assuming that pressure and the number of moles of He remains constant? 5. What volume, in L, is occupied by 10.0 g N, at 30.0°C and a pressure of 385 mm Hg?
Question 5 5 pt A 20.2 L cylinder that has a moveable piston is filled with gas X at a pressure of 0.966 atm at 45.0°C If the piston is pulled up (expansion) so that the new volume is 36.7 L and the new pressure is 0.555 atm, what is the new temperature (in K) assuming constant amount of gas X? 332 309 47.0 0.00301 Question 6 5 pts A mixture of gases containing only three types of gases (Ne,...
