Atank of volume 0.25 ft is designed to contain 50 standard cubic feet of air. the temperature is 80° f. calculate the pressure inside the tank. one standard cubic foot of air occupies foot at standard 'temperature and pressure (t 59° f and p= 2116 lb/ft2). one cubic

The inside Pressure of the tank is

Solution:

As per the question:

Volume of tank,

The capacity of tank,

Temperature, T' = = 299.8 K

Temperature, T = = 288.2 K

Now, from the eqn:

PV = nRT                      (1)

Volume of the gas in the container is constant.

V = V'

Similarly,

P'V' = n'RT'                       (2)

Also,

The amount of gas is double of the first case in the cylinder then:

n' = 2n

where

n and n' are the no. of moles

Now, from eqn (1) and (2):

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

temp rises, and expansion
