Answer:
The value is the temperature of the air inside the tire
340.54 K
% of the original mass of air in the tire should be released 99.706 %
Explanation:
Initial gauge pressure = 2.7 atm
Absolute pressure at inlet
= 2.7 + 1 = 3.7 atm
Absolute pressure at outlet
= 3.2 + 1 = 4.2 atm
Temperature at inlet
= 300 K
(a) Volume of the system is constant so pressure is directly proportional to the temperature.


340.54 K
This is the value is the temperature of the air inside the tire
(b). Since volume of the tyre is constant & pressure reaches the original value.
From ideal gas equation P V = m R T
Since P , V & R is constant. So
m T = constant




value of the original mass of air in the tire should be released is

⇒ -0.99706
% of the original mass of air in the tire should be released 99.706 %.
Answer:
26 electrons
A neutral iron atom contains 26 protons and 30 neutrons plus 26 electrons in four different shells around the nucleus. As with other transition metals, a variable number of electrons from iron's two outermost shells are available to combine with other elements

Answer:
A) 
B) 
Explanation:
Given:
- temperature of air,

- temperature of lungs,

- specific Heat exchanged from the lungs ,

- specific heat of air,

- mass of 1 L air,

- breath rate,

A)
Now,
amount of heat needed to warm the air of lungs to the body temperature:



B)
Amount of heat lost per hour:
<u>No. of breaths per hour:</u>



<u>Now the total loss of energy in 1 hr.:</u>
