Perfect gas equation applies very closely to ________ gases.

high temperature, low pressure

high temperature, high pressure

low temperature, low pressure

low temperature, high pressure

Correct Answer : high temperature, low pressure

Explanation : Perfect gas equations are valid for high temperature and low-pressure gases. In such a case, the inter-molecular forces are negligibly small. PV=RT is the perfect gas equation, with V as the specific volume, P as the pressure, T as the temperature and R as the gas constant for the mixture of gases.

1-methyl-1, 2-dicyclopropyl cyclopropane is also called as _______

RP-1

Jet fuel

Syntin

Kerosene

Correct Answer : Option (C) : Syntin

Explanation : Syntin is a high-energy formulation briefly used in the upper stages of rockets developed by the Soviet Union. Its molecular formula is C₁₀H₁₆ and it is a mixture of 4 stereoisomers.

The fuel which releases the most energy per unit mass of combustion is ______

RP-1

LH₂

Kerosene

Methane

Correct Answer : Option (B) : LH₂

Explaination : Compared to hydrocarbon fuels, liquid hydrogen delivers most energy per unit mass of combustion. Any hydrocarbon fuel, when subjected to combustion produces more pollution than LH₂.

Which of the following fuels were used in the first stage of Titan I?

RP-1

RDX

HMX

None of the above

Correct Answer : Option (A) : RP-1

Explanation : RP-1 fuel is used in the first stage of Titan 1. Other than that, it was also used in the first stages of Saturn V, Energeia, Saturn I and IB etc. It is a cheaper and less explosive alternative to LH₂.
