Is this question for schoolwork?kelseytischler95 said:TL;DR Summary: Thermal expansion of neon i need help.
If neon is stored at 40 psi . 65 degrees fahrenheit. How do i calculate the psi in a closed system when the container is heated.
Not in the slightest. Any help would be greatly appreciated.berkeman said:Is this question for schoolwork?
Does neon behave as an ideal gas at this temperature and pressure?Baluncore said:Volume is fixed.
P1 / T1 = P2 / T2 ;
where Temperatures are absolute.
What is stopping you?
Thermal expansion refers to the tendency of matter to change in volume in response to a change in temperature. When a substance is heated, its particles move more vigorously and tend to occupy a larger volume, leading to expansion.
In gases, thermal expansion is primarily observed as an increase in pressure or volume when the temperature rises, assuming the amount of gas remains constant. For neon, an inert gas, this means that as the temperature increases, the kinetic energy of the neon atoms increases, causing them to move apart and occupy a larger volume.
The volume expansion of an ideal gas can be approximated using the formula: ΔV = V0 * β * ΔT, where ΔV is the change in volume, V0 is the original volume, β is the coefficient of volumetric expansion, and ΔT is the change in temperature. For ideal gases, the coefficient of volumetric expansion can be approximated as β = 3 * α, where α is the coefficient of linear expansion.
The thermal expansion of neon is primarily affected by temperature changes and the initial volume of the gas. Additionally, the pressure conditions can influence how neon expands, particularly if it is contained in a rigid container versus an expandable one.
To measure the thermal expansion of neon in a laboratory, you can use a closed container with a pressure gauge. By heating the container and monitoring the pressure changes, you can calculate the volume change of neon using the ideal gas law, which relates pressure, volume, and temperature. This allows for the determination of how much the volume of neon expands with temperature increase.
