# How fast do it take a gas kinetic energy to react to intense heat? [closed]

Let's say I have argon gas in a small container. And opened the flap of the container and stuck a rode that was around 2000-3000 Degrees Fahrenheit, And was only in there for a millisecond. How long will it take the heat to transfer to the gas raising the kinetic energy, causing extreme pressure? Let's also add the gas was frozen to around -5 F. I need to know how fast it take to change the kinetic energy of a gas. And how to make it happen as fast as possible?

P.S Would the heat spread evenly in that short of time frame?

I think you are mistaken - while the rod is placed in the container, it will heat up the air via a process known as convection. According to wikipedia, the rate of convection is given by $\frac{dQ}{dt}= hA(T_a-T_b)$ where $\frac{dQ}{dt}$ is the rate of heat transfer, h is a constant for the material, A is the exposed surface area, $T_a$ is the surface temperature of the object, and $T_b$ is the temperature of the gas around the material. My guess is that even at those temperatures, one millisecond will not be enough for the increase in pressure to be as extreme as you are looking for, as the gas around the rod will quickly heat up, but this heat will take a relatively long time to diffuse. As the air around the rod heats up, the rate of heat flow from the rod to the environment will slow down, meaning that only a small amount of the gas in your container will have heated up to a significant temperature.
