Question

In Joule's Thomson effect there is fall in temperature of gas occur due to _______​

Answer 1

Explanation:

However, at atmospheric pressure, as the inversion temperature for hydrogen is low (202K) and hence hydrogen will warm during a Joule–Thomson expansion at room temperature.

...

Solution:

T (°C) V (m3/kg) H (kJ/kg)

240 0.2400 2922.6

260 0.2506 2967.0

280 0.2614 3010.5

Answer 2

Answer:

This is due to a decrement in kinetic energy.

Explanation:

According to Joule Thomson: When a gas at high pressure is allowed to expand adiabatically through a fine hole to low pressure, it will start getting cool.

The reason for cooling is that when the gas expands from a higher region to a lower region, the inter-molecule distances increase. This is done by kinetic energy which then decreases, cooling the gas.

Conclusion:

In Joule's Thomson effect there is a fall in the temperature of gas occurring due to a decrement in kinetic energy.
