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

answer: the correct answer for the fill in the blank is rods.

rods are the specialized photoreceptor cells that are present in the retina of human eye. they are responsible for vision in the night time ( also called scotopic vision). they have very low visual acuity and color distinguishing ability.

as they are responsible for vision in night time, therefore they are found predominantly in the nocturnal animals.
