Description : A real gas can act as an ideal gas in - (1) high pressure and low temperature (2) low pressure and high temperature (3) high pressure and high temperature (4) low pressure and low temperature
Last Answer : (2) low pressure and high temperature Explanation: Real gases approximate ideal gases when their pressure is relatively low, and their temperature reasonably high. A real gas deviates increasingly from ideality as it is compressed and cooled to near the point at which it will condense into a liquid.
Description : The average kinetic energy of the molecules of an ideal gas is directly proportional to – (1) Velocity of Molecules (2) Mass of Molecules (3) Absolute temperature of the gas (4) Temperature of environment
Last Answer : (3) Absolute temperature of the gas Explanation: The average kinetic energy of gas molecules is directly proportional to absolute temperature only. This implies that all molecular motion ceases if the temperature is reduced to absolute zero.
Description : If we double the temperature of an ideal gas, then it's average kinetic energy will be A. halved B. triple the original C. fourth times of original D. doubled
Last Answer : doubled
Description : If two different gases have the same volume, temperature, and pressure and behave like ideal gases, they will also be identical in which one of the following ways? w) average molecular velocity x) total mass y) total molecular kinetic energy z) average momentum per molecule
Last Answer : ANSWER: Y -- TOTAL MOLECULAR KINETIC ENERGY

Last Answer : ANSWER: 75 PERCENT
Description : Under which of the following conditions does the behavior of a real gas resemble that of an ideal gas? Is it: w) under all conditions of temperature and pressure x) only at very high pressure ... when the gas is near condensation z) only at low densities when the molecules are relatively far apart
Last Answer : ANSWER: Z -- ONLY AT LOW DENSITIES WHEN THE MOLECULES ARE RELATIVELY FAR APART
Description : According to the kinetic theory, the Kelvin temperature of an ideal gas is proportional to which one of the following. Is the temperature proportional to the gas's average molecular: w) velocity x) momentum y) kinetic energy z) potential energy
Last Answer : ANSWER: Y -- KINETIC ENERGY
Description : The average kinetic energy of the molecules of an ideal gas is directly proportional to (1) Velocity of Molecules (2) Mass of Molecules (3) Absolute temperature of the gas (4) Temperature of environment
Last Answer : Absolute temperature of the gas
Description : A real gas can act as an ideal gas in (1) high pressure and low temperature (2) low pressure and high temperature (3) high pressure and high temperature (4) low pressure and low temperature
Last Answer : low pressure and high temperature
Description : What are the features of Ideal Transformer ?
Last Answer : Answer : Features of Ideal Transformer: Winding resistance will be very low. It will have no leakage flux. There will be no loss in the core. The permeability of the core is very high.
Description : What is Ideal Transformer ?
Last Answer : Ideal Transformer: Ideal or standard transformer is a type of transformer which has no power loss. That means 100% of the input power can be found in the output. But in reality there is no machine or ... types of machines have power loss. But the power loss of the transformer is much less.
