if there's a vacuum above the piston what is the combined weight of pain and masses in Newtons
Remove Looking pin 50 cm 1.0 atm 20°C 100 cm 3.0 am WWW 1. Start 2. Heat to 3 atm. 3. Remove pin. Continue heating to 100 cm 4. Insert pin. Remove mass The figure shows a sample of N2 gas covered by a movable piston, first in its initial state and then undergoing three processes. The heat capacity at constant volume for Nz is 5/2 R. In step 1, when the pin locking the piston is removed, the piston does not move. The piston has an area of 10 cm². The figure gives the volume, pressure, and temperature of the gas. If there is a vacuum above the piston, what is the combined weight of the piston and masses, in Newtons? Please express all answers to three significant figures.

Solution: Free Imag Making body diagsean for stept Since piston dans not move, therefore were total weight is balanced by force due to internal pressure developed gas. Area of piston= loom? - 10x10 m² Internal pressure - Latm Let total mass= m. in the P=hatm At equilibrium, Fore Force downward = Force upward. mxg = Рx fta. mx 9. 8 = 101825x105 10x106 ma 0.1034 101N mess, 0.1034 kg 1034 g Combine weight = mxg = 1.01325 Nm In 3 significant understood!) if you # Hit like
