change a when the gas goes from liquid to gas is a physical change. Change b when the gas burns is a chemical change
When LPG comes out of the cylinder, it changes from a liquid to a gas which is a physical change. When it burns, it undergoes a chemical change where it reacts with oxygen to produce heat, light, carbon dioxide, and water vapor.
When LPG comes out of the cylinder and burns, it undergoes combustion with oxygen in the air. This reaction releases heat energy, causing LPG molecules to break down into carbon dioxide and water vapor. The physical changes include the release of heat, light, and the formation of gases like carbon dioxide and water vapor.
When LPG comes out of the cylinder, it changes from a liquid to a gas due to the decrease in pressure. This phase change causes it to expand rapidly and cool down, which is why LPG feels cold when released. The gas is then ready to be ignited and used as a fuel for various applications.
The process of LPG turning from liquid to gas is a physical change, not a chemical change. It involves a change in state, from liquid to gas, without any alteration in the chemical composition of the LPG molecules.
When LPG gas burns on a gas stove, it undergoes a chemical change as it reacts with oxygen to produce heat, light, carbon dioxide, and water vapor. This is a combustion reaction. The physical change involved is the change in state of the gas from a liquid to a gaseous form as it is released from the cylinder and then burns.
If you have a physical cylinder to measure, measure the "width" of the circle that is the cross section of the cylinder. That is the diameter, Half the diameter is the radius.
Physical damage to a cylinder is seldom repaired. More often the motor is replaced.

The test pressure is always stamped on the cylinder along with the working pressure, physical volume, manufacture date etc. It is generally about twice the working pressure of the cylinder.
An LPG cylinder may bulge due to overfilling, exposure to high temperatures causing the gas inside to expand, or physical damage to the cylinder. Bulging can weaken the structural integrity of the cylinder and increase the risk of a leak or rupture, posing a safety hazard. It is important to handle LPG cylinders carefully and store them properly to prevent bulging.

A four cylinder engine can be built to be EXTREMELY powerful, either my machining of the physical metal (head and block) to allow for more cylinder displacment and volumetric efficiency, or by use of "power adders" such as tubro or supercharger kits, nitrous oxide, and various intake systems. The limit is your imagination (and your wallet). -Ben
The density of the brass block and brass cylinder should be very similar since they are both made of the same material, brass. Density is a physical property that is unique to each material and is determined by the mass of the material divided by its volume. Therefore, as long as the block and cylinder are made of the same brass material, their densities should be close.
The size of an engine is usually defined by its total cubic capacity. Therefore a four cylinder engine could be 'bigger' than a V12, and vice versa. This is also true of the physical size. There are huge four cylinder engines on ships for instance
An incorrect fouler and a cracked piston ring.

The motion of a cylinder rolling down an inclined plane demonstrates the principles of physics through the interaction of forces such as gravity, friction, and rotational motion. As the cylinder moves, gravitational force pulls it downward, while friction between the cylinder and the inclined plane affects its speed and direction. The rotational motion of the cylinder also plays a role in its movement, showcasing concepts like torque and angular momentum. Overall, this scenario illustrates how various physical forces and principles come into play to determine the motion of an object on an inclined plane.
