Real gas

During a science experiment, Ishika observed that above Boyle temperature, real gases behave differently than ideal gases. She noted that they show __________ deviation from ideal gases.

• negative

• positive

• no

• both positive and negative

Aisha is studying the properties of gases in her chemistry class. She learns that compressibility can be expressed as _______

• real volume divided by the ideal volume

• real universal gas constant by ideal universal gas constant

• real temperature by ideal temperature

• real volume divided by real pressure

Aanya is conducting an experiment in her chemistry lab to understand the behavior of gases. She learns about a specific temperature at which a real gas behaves like an ideal gas and follows Boyle’s law. What is this temperature called?

• Boyle temperature

• Charge temperature

• Critical temperature

• Absolute Temperature

Imagine Eesha is conducting an experiment in her chemistry lab. She wants to understand the behavior of gases under different conditions. Which of the following conditions do you think a real gas behaves as an ideal gas during her experiments?

• high pressure

• low pressure

• intermediate pressure

• at any pressure

Aanya is conducting an experiment in her chemistry lab to study the behavior of gases. She wants to know under which conditions a real gas most closely approaches the behavior of an ideal gas.

• high P and low T

• low P and high T

• low P and T

• high P and T

Krish is conducting an experiment to study the compressibility factor "Z" versus pressure "P" for three different gases. He observes the graphs for gases A, B, and C. Which of the gases will have more interaction energy?

• A

• B

• C

• all have same interaction

Tara is conducting an experiment with four gases: CH₄, NH₃, H₂O, and HF. At very low pressure and high temperature, she wonders if the volume of all the gases will be the same.

• Yes

• No

Saisha is conducting an experiment in her chemistry lab where she compresses a real gas in a sealed container. As she increases the pressure, she notices that the gas particles come closer together and eventually form a liquid. Curious about the effects of temperature, she wonders if there is a temperature beyond which she cannot achieve a liquid state, regardless of how much pressure she applies. What do you think?

• Yes, definitely there is temprature beyod which a liquid state is not possoble .

• No, all real gas do convert ot liquid state at any T.

During a chemistry experiment, Kiara is studying the behavior of gases at low pressure and high volume. She is particularly interested in the compressibility factor of gases like CH4, NH3, and H2O. What will be the value of the compressibility factor for these gases under these conditions?

• Z=1

• Z>1

• Z<1
