The volume of an ideal gas is increased from 0.61 m3 to 3.9 m3 while maintaining a constant pressure of 970 Pa (1 Pa = 1 N/m2). If the initial temperature of the gas is 65 K, (a) What is the final temperature of the gas?

416K

Step-by-step explanation:

Given:

Initial volume = 0.61 m^3 => 610L

Final volume = 3.9 m^3 => 3900L

Initial temperature = 65 K

Final temperature =?

Charles law states that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.

Therefore,

/ = /

610/ 65 = 3900 /

= (3900 x 65) / 610

=  415.5 K ≈ 416K

The final temperature of the gas is 416K

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
