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:

If the following structure is written to a file using fwrite(), can fread() read it back successfully?

struct emp

{

    char *n;

    int age;

};

struct emp e = { "Sujay",15};

FILE *fp;

fwrite (&e, sizeof (e), 1, fp);

Answer

No, since the structure contains a char pointer while writing the structure to the disk using fwrite() only the value stored in the pointer n would get written. When this structure is read back the address would be read back but it is quite unlikely that the desired string would be present at this address in memory

Q:

Can 8259 he interfaced with 8085 via the trap pin?

Answer

Yes... so if 8529 gives interrupt then it will be serviced immediately but since INTA pin is left hanging the INSR bit will never be set.. and so whenever my interrupt occurs depending upon priority it will be serviced.. also the ISR address for all interrupts will be same ie 0024H..


Interrupt via trap is nonmaskable, so it will be serviced immediately.

Q:

Tetraethyl lead is used as

A) Fire extinguisher B) Gasoline additive
C) Mosquito repellent D) Pain killer
 
Answer & Explanation Answer: B) Gasoline additive

Explanation:

Tetraethyl lead is a highly toxic compound used as a gasoline additive.

Tetraethyl lead abbreviated as TEL, is an organo lead compound with the formula (CH3CH2)4Pb. It is a petro-fuel additive which in turn caused increased vehicle performance. This is also used as an antiknock agent in gasoline and jet fuels. Tetraethyl lead is absorbed rapidly by the skin, the lungs, and the gastrointestinal tract. It is converted to triethyl lead, which might be responsible for its toxicity.

Q:

Which type of simple sugar is found primarily in fruit?

A) Sucrose B) Fructose
C) Maltose D) Lactose
 
Answer & Explanation Answer: B) Fructose

Explanation:

The main simple sugar found in fruit is Fructose. Glucose is found naturally occurring in fruits and other plants. But fructose is sweeter than glucose and can give you more energy. That's why a piece of fruit in the morning will give you more energy than a cup of coffee!

 

Fructose is what gives most fruits that sweet flavor and in combination with the acids present in certain fruits can give a pleasantly tangy flavor.
