How to calculate temperature of expanded ideal gas.

By definition an ideal gas in a closed follows the relationship of PV=nRT, or PV/T = constant

This means that Pressure * Volume/ Temperature will be the same at the start and end of the p...

How does conduction work in metals?

A metal has free electrons, so when it is heated these electrons gain kinetic energy, meaning they move faster. As a result, these free electrons will collide with other electrons or ions, transferring en...

A rocket travels at 500m/s two minutes after its take-off. If it was initially stationary, calculate its acceleration. If the rocket has a mass of 1800kg, what force is required to give it an acceleration of 2m/s^2?

a) Acceleration is the rate of change of velocity of an object

In this case, the equation that we will use to calculate it is 

a = (v - u )/ t
