Line d represents water. if the atmospheric pressure in a flask is lowered to 70 kpa, water would boil at what temperature?
1 answer:
The diagram is in the picture attached.
Options are:
A) 32 °C
B) 70 °C
C) 92 °C
D) 100 °C
In order to find the value required, you need to look at the diagram and follow these steps:
1) search for the value of 70 kPa on the y-axis;
2) move on a horizontal line towards the right until you reach the line D;
3) move on a vertical line down, towards the x-axis;
4) read at what value of °C you are at.
Doing so, you can see that you are at a value a little bit above 90 °C (see picture).
Hence, the correct answer is C) 92°C.

Answer:
The time constant becomes twice.
Explanation:
= Time constant of the L-R circuit
= Inductance of the inductor
= Resistance of the resistor
Time constant of the L-R circuit is given as
= initial time constant of the L-R circuit =
= final time constant of the L-R circuit
= Initial inductance of the inductor =
= Initial inductance of the inductor =
For the same resistance, the time constant depend directly on the inductance, hence
