An ideal gas within a closed system undergoes an isothermal expansion from an initial volume of 1m^3 to 2m^3. Given that the initial pressure of the gas is 10^5 Pa, find the final pressure of the gas following the expansion.

The key word to note in this question is that the expansion is isothermal and that we have a closed system . This means that the expansion must happen at a constant temperature (isothermal), and that the num...

What is the difference between an elastic and inelastic collision

In all collisions momentum is conserved. However in elastic collision kinetic energy is also conserved, molecules colliding is an elastic collision.If kinetic energy is not conserved that then the collision ...

Using newtons laws explain how a falling object can reach terminal velocity (6)

So we need to break this down into two parts, what are Newtons laws and what is terminal velocity? In this case we will only need the first two of Newtons laws. Number one " An object will remain at res...

What does a stress-strain curve for a metal look like and what does each part mean?

Stress is force divided by area, this is plotted on the y axis. Strain is extension divided by original length, this is plotted on the x axis. In the process of recording data to plot a stress-strain curve, ...

Can you explain the difference between distance and displacement

Distance is a scalar which means it only has a length- it is the length of distance travelled along a pathDisplacement is a vector which means it has a direction and a length and is the total change in posit...
