You start driving your car when the air temperature is 270.734 K. The air pressure in the tires is 454.518 kPa. After driving a

while, the tire's air pressure increases to 470.361 kPa. What is the temperature of the tires at that point, assuming the volume remains constant

Answer:

T₂ =  280.17 K

Explanation:

Here, we can use the equation of state to find the final temperature of air in tires. Equation of State is written as follows:

\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}

Since, the volume is constant.

Therefore,

V_{1} = V_{2} = V\\\\\frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}}\\\\T_{2} = \frac{T_{1}P_{2}}{P_{1}}

where,

T₂ = Final Temperature of Air in Tire= ?

T₁ = Initial Temperature of Air = 270.734 K

P₁ = Initial Pressure of Air = 454.518 KPa

P₂ = Final Pressure of Air = 470.361 KPa

Therefore,

T_{2} = \frac{(270.734\ K)(470.361\ KPa)}{454.518\ KPa}

<u>T₂ =  280.17 K</u>

The difference in the composition of the terrestrial planets and the gas giants can be explained by the different condensation
miv72 [106K]
The inner planets are usually rocky because the gravitational pull is stronger closer to the star or in this case the sun. The dust and rocky particles that are left over after a super nova or in a nebula will tend to orbit closer to a proto-star when a solar system is in its early days. In our solar system these planets are Mercury, Venus, Earth and Mars. Gases are less dense and will be less affected by the pull of gravity because rocky particles have more mass. The outer planets are gas giants formed from clouds of gas that would be further out in the spinning disk around a proto-star.

A 12 oz can of soda is left in a car on a hot day. In the morning the soda temperature was 60oF with a gauge pressure of 40 psi.
Neko [114]
In this case, volume of the can remains constant. The relationship between pressure and temperature at constant volume is given by:

P/T = Constant

Then
\frac{ P_{1} }{ T_{1} } = \frac{ P_{2} }{ T_{2} }

Where
P1 = 40 psi
P2 = ?
T1 = 60°F ≈ 289 K
T2 = 90°F ≈ 305 K (note, 363 K is not right)

Substituting;
P_{2} = \frac{ P_{1}  T_{2} }{ T_{1} } = \frac{40*305}{289}  =42.21 psi
