A gas syringe is being heated and the piston begins to be move outwards and eventually stops. Explain. Upon heating, the gas pressure increases to more than that of the atmospheric pressure. As a result, a resultant force acts outwards which pushes the piston outwards. As the piston moves outwards, the volume of the cylinder increases, causing the gas pressure to decrease. When the gas pressure drops back to a value equal to that of atmospheric pressure, there will be no more resultant outward force and the piston will stop being pushed out.

If some heat is transferred to the gas and its volume is doubled, do you expect the pressure inside the cylinder to change?
Consider the piston-cylinder. In the initial system, 1 mol of gas is in the state of 2 bar and 10 L. When the ring that fixed the piston was released, the expansion occurred and the final volume was 15.2 L. At this time, the external pressure is 1 bar. Seek what this system has done about aliens. Consider the sign, value, and unit.
Figure 1 shows a piston-cylinder assembly containing gas, on top of a hot plate. At the beginning, the system is at room temperature, and the piston seats on the set of stops. Then, the heating plate is turned on and eventually the piston starts to rise. Determine at which pressure this happens, considering that g = 9.81 m/s 2.
Assuming compression is according to the law PV = constant. Calculate the initial volume of gas at a pressure of 2 bar which will occupy a volume of 6 cubic meters when it is compressed to a pressure of 42 bar.
Answer the following questions with solution/ detailed explanation: 1. The pressure in an automobile tire depends on the temperature of the air in the tire. When the air temperature is 25°C, the pressure gage reads 210 kPa. If the volume of the tire is 0.025 m3, determine the pressure rise in the tire when the air temperature in the tire rises to 50°C. Also, determine the amount of air that must be bled off to restore pressure to its original value at this temperature. Assume the atmospheric pressure to be 100 kPa.
2. If 100 ft3 of atmospheric air at zero Fahrenheit temperature are compressed to a volume of 1 ft³ at a temperature of 200 F, what will be the pressure of the air in psi?
3. There is an abnormal gas in the cylinder. It is compressed from a volume of 300 (liters) and a pressure of 0.1 MPa to a volume of 1000 and a pressure of 0.7 MPa. When the state of the gas can be described by the relation of'PI = constant', find the value of n and the work done by the gas (kJ).
3. Two spherical vessels of different sizes contain the same gas and are connected by means of a pipe with a valve. Sphere A has a diameter of 5 foot at the given pressure gauge of 50 kgf/cm2. Sphere B contains the same gas at 20 kgf/cm2 gauge. The valve is opened and when the properties have been determined, it is found out that the gauge pressure is 36 kgf/cm2. The temperature at the two vessels before and after opening the valve is maintained at 21.1oC. If the gas inside the sphere is ammonia, find the following: -The pressure of the gas when mixed in psia -The temperature of the gas when mixed in K -The atmospheric pressure in psi -The diameter of Sphere B -The total mass of the gas after opening the valve

As shown on the right, a vertical piston–cylinder assembly containing a gas is placed on a hot plate. The piston initially rests on the stops. With the onset of heating, the gas pressure increases. At what pressure, in bar, does the piston start rising? The piston moves smoothly in the cylinder and g = 9.81 m/s2.
