Vesnalui [34]

Answer:

A) Having a positive slope

D) Approaching zero pressure as temperature approaches infinity

Explanation:

A fixed amount of ideal gas is kept in a container of fixed volume. The absolute pressure P, in pascals, of the gas is plotted as a function of its temperature T, in degrees Celsius. Which of the following are properties of a best fit curve to the data? Select two answers.

A) Having a positive slope

B) Passing through the origin

C) Having zero pressure at a certain negative temperature

D) Approaching zero pressure as temperature approaches infinity

solution

from the ideal gas equation

PV=nRT

P=pressure

T=absolute temperature in kelvin

V=volume

R=gas constant 8.314j/molK

n=mole= mass/molecular mass

P=nRT/V

nR/V is the constant

P=nR(Tc+273)/V

plotting the graph we will discover that as pressure increases , temperature also increases . which means it's a positive graph.

Also Approaching zero pressure as temperature approaches infinity

Freight trains can produce only relatively small accelerations and decelerations. What is the final velocity of a freight train

inn [45]

Answer:

Final speed of the train, v = 168.61 m/s

Explanation:

It is given that,

Acceleration of the train, $a=0.71\ m/s^2$

Time taken, t = 3.85 min = 231 s

Initial velocity of the train, u = 4.6 m/s

We need to find the final velocity (v) of the train. It can be calculated using first equation of motion as :

$v=u+at$

$v=4.6+0.71\times 231$

v = 168.61 m/s

So, the final velocity of the train is 168.61 m/s. Hence, this is the required solution.
