The pressure in an automobile tire depends on the temperature of the air in the tire. when the air temperature is 25°c, the pressure gage reads 210 kpa. if the volume of the tire is 0.025 m3, determine the pressure rise in the tire when the air temperature in the tire rises to 50°c. also, determine the amount of air that must be bled off to restore pressure

0.0704 kg

Explanation:

Given

initial Absolute pressure=210+101.325=311.325

as the volume remains constant therefore

therefore Gauge pressure is 337.44-101.325=236.117 KPa

Initial mass

Final mass

Therefore =0.91-0.839=0.0704 kg of air needs to be removed to get initial pressure back

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
