Q:

Which law relates to the ideal gas law?

A) P1T1 = P2T2 B) P1/V1 = P2/V2
C) P1V1 = P2V2 D) T1/V1 = T2/V2
 
Answer & Explanation Answer: C) P1V1 = P2V2

Explanation:

Ideal Gas Law ::

The Combined gas law or General Gas Equation is obtained by combining Boyle's Law, Charles' Law, and Gay-Lussac's Law. It shows the relationship between the pressure, volume, and temperature for a fixed mass (quantity) of gas:

P1V1T1 = P2V2T2

 

Hence, the Boyle's law P1V1 = P2T2, relates to ideal gas equation.

Q:

A pulse can be detected most easily in

A) a vein B) a lacteal
C) an artery D) a capillary
 
Answer & Explanation Answer: C) an artery

Explanation:

A pulse can be detected most easily in Arteries as they are under much greater pressure than veins because they are carrying blood away from the heart which is the pumping machine to force blood to move to all of the body.

 

Every time the hear contracts, it can be felt in an artery where a surge of blood has just been forced.

 

A capillary is too small to feel a pulse and a lacteal is part of the lymphatic system found in the small intestine.

Q:

A number when subtracted by 1/7 th of itself gives the same value as the sum of all the angles of a triangle. What is the number?

A) 420 B) 210
C) 70 D) 35
 
Answer & Explanation Answer: B) 210

Explanation:

Let the required number be 'p'

We know, sum of angles in a triangle are 180 deg

According to given data,

p - p/7 = 180

7p - p = 180 x 7

=> 6p = 1260

=> p = 1260/6 = 210

Q:

Planets do not twinkle because

A) Far distance B) Total internal reflection
C) Refraction D) Near distance
 
Answer & Explanation Answer: D) Near distance

Explanation:

Stars twinkle because they’re so far away from Earth that when light from the stars passes through the atmosphere, it is bent countless times due to refraction, making it look like as if they were blinking. The sun and other planets doesn’t twinkle because it’s too close to Earth compared to other stars.
