What’s boyles law
Boyle’s Law states that the product of the pressure and volume of any given mass of gas is constant providing that the temperature of the gas remains unchanged
T = constant
P × V = constant
If P increases V decreases
If P decreases V increases
What’s Charles law
Charles’ Law states that, providing that the pressure of the gas remains unchanged, the volume of any given mass of gas is proportional to the temperature
P = constant
V / T = constant
If T increases V increases
If T decreases V decreases
What’s guy lussacs law (the pressure law)
Gay-Lussac’s law states that, providing that the volume of the gas remains unchanged, the pressure of any given mass of gas is proportional to the temperature
V = constant
P / T = constant
T increases P increases
If T decreases P decreases
By combining Boyle’s, Charles’ and Gay-Lussac’s laws, the general gas equation (or combined gas law) can be obtained:
PV/T = constant
Heat can be transferred in three fundamental ways:
Conduction Between elements in physical contact
•Convection Between an object and the environment due to fluid motion
•Radiation Via emission of photons in electromagnetic waves
What laws of motion are seen in action in the piston engine
-To move a stationary object or to make a moving object change its direction, a force must be applied
-The air/fuel mixture does not move into the cylinder spontaneously, some force must draw it inside
-The piston moving down in the cylinder does not stop spontaneously. The opposition of a body to change its motion is called inertia
What’s thrust
second and third laws.
When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction on that system.
Thrust (T) = Force
Force = Mass (m) × Acceleration (a)
