Q:

For an ideal gas, which one of the following statements does not hold true?

A) The speed of all gas molecules is same B) The kinetic energies of all gas molecules are not same
C) The potential energy of the gas molecules is zero D) There is no interactive force between the molecules.
 
Answer & Explanation Answer: A) The speed of all gas molecules is same

Explanation:

In an ideal gas, at any particular time, different particles in the gas have different speeds and hence different kinetic energies. This assumption is reasonable because as the particles collide, we expect their speed to change. Even if initial speed of all the particles was same, the molecular collisions will disrupt this uniformity.Hence statement 1 is incorrect and 2 is correct.

Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives and click the button corresponding to it.

The first working steam­ powered vehicle was designed and most likely built by Ferdinand Verbies, a Flemish member of a Jesuit mission in China around 1672. It was a 65 cm long scale­ model toy for the Chinese Emperor, that was unable to carry a driver or a passenger. It is not known if Verbiest's model was ever built. Nicolas- Joseph Cugnot is widely credited with building the first full­ scale, self ­propelled mechanical vehicle or automobile in about 1769; he also created a steam­ powered tricycle. He constructed two steam tractors for the French Army, one of which is preserved in the French National Conservatory of Arts and Crafts. His inventions were however handicapped by problems of water supply and maintaining steam pressure. In 1801, Richard Trevithick built and demonstrated his Puffing Devil road locomotive, believed by many to be the first demonstration of a steam ­powered road vehicle. It was unable to maintain sufficient steam pressure for long periods. Sentiment against steam ­powered road vehicles led to the Locomotive Acts of 1865. In 1807 Nicephore Niepce and his brother Claude probably created the world's first internal combustion engine which they called Pyreolophore.

The Pyreolophore was ?

A) A self­propelled mechanical vehicle B) A steam-­powered tricycle
C) A steam tractor D) The name of the world's first internal combustion engine
 
Answer & Explanation Answer: D) The name of the world's first internal combustion engine

Q:

Which of the following is a property of water?

A) High polarity B) Universal solvent
C) High specific heat D) All of the above
 
Answer & Explanation Answer: D) All of the above

Explanation:

Yes, we know that water is a universal solvent.

 

Water can moderate temperature because of the two properties: high-specific heat and the high heat of vaporization.

 

Water is a polar molecule that has a high level of polarity and attraction to ions and other polar molecules.

 

Hence, all the above given options are the properties of water.
