2. If a 3 m3 tank contains 45 kg of oxygen at 50°c, what is the gage pressure in the tank? the specific gas constant of oxygen is r=0.25983 kj/kg-k.
Answer:
1370.5 kPa.
Explanation:
To calculate the gauge pressure in the tank, we can use the ideal gas law, which relates the pressure, volume, temperature, and number of moles of a gas:
PV = nRT
where P is the absolute pressure of the gas, V is the volume of the tank, n is the number of moles of the gas, R is the specific gas constant, and T is the absolute temperature of the gas.
First, we need to calculate the number of moles of oxygen in the tank. We can use the mass of the oxygen and its molar mass to find the number of moles:
n = m/M
where m is the mass of the oxygen and M is the molar mass of oxygen (32 g/mol).
m = 45 kg = 45000 g
M = 32 g/mol
n = 45000 g / 32 g/mol = 1406.25 mol
Next, we need to convert the temperature to absolute temperature in Kelvin:
T = 50°C + 273.15 = 323.15 K
Now we can use the ideal gas law to solve for the absolute pressure:
P = nRT/V
P = (1406.25 mol)(0.25983 kJ/kg-K)(323.15 K)/(3 m^3) = 1471.8 kPa (absolute pressure)
Finally, we can convert the absolute pressure to gauge pressure by subtracting the atmospheric pressure. Assuming standard atmospheric pressure of 101.3 kPa, we get:
P_gauge = P_absolute - P_atm = 1471.8 kPa - 101.3 kPa = 1370.5 kPa
Therefore, the gauge pressure in the tank is 1370.5 kPa.

PANGALAWANG WIKA – Sa paksang ito, aalamin natin kung ano ang mga halimbawa ng pangalawang wika at kung saan ito matatagpuan.Ang Pilipinas ay may angking kalamangan sa ibang mga bansa. Ito ay dahil sa iba’t-ibang wika na ginagamit sa Pilipinas. Dahil sa pagiging isang arikipelago, maraming mga isla na may sarili nilang kultura at wika.
Answer:
Ang pangalawang wika ay tumutukoy sa anumang wika na natutunan ng tao matapos niyang maunawaan ng lubos ang kanyang wikang kinalakihan o ang kanyang sariling wika. Ang pagkakaroon ng pangalawang wika ay maaaring bunga ng pag-aaral o kaya naman ay migrasyon.
Isa ng halimbawa nito ay sa Pilipinas. Ang karaniwang unang wika ng mga Pilipino ay Tagalog. Ang pangalawang wika naman ay ang Ingles.

Ang palaisipan ay isang suliranin o uri ng bugtong (enigma) na sinusubok ang katalinuhan ng lumulutas nito. Sa karaniwang palaisipan, inaasahan na lutasin ang palaisipan sa pamamagitan ng pagsama-sama ng mga piraso sa isang lohikal na paraan para mabuo ang solusyon. Kadalasang nililikha ang mga palaisipan bilang isang uri ng libangan, ngunit maaari rin namang magmula ito sa seryosong matematikal at lohistikal na suliranin — sa mga ganitong kaso, ang kanilang matagumpay na pagkalutas ay isang mahalagang ambag sa pagsaliksik sa matematika.[1]

20. A motorist starts a trip with a pressure of 200 kPa (gage) and a temperature of 23°C in the tires. After a long drive, the temperature of the air in the tires reached 83°C, the tire contains 0.11 kg of air. Assuming a constant volume, compute the following: Use constant R. a. Pressure when it reached 83°C b. The volume of the tire.
Answer:
We treat the air in the tires as an ideal gas and solve the missing values accordingly.
Ideal gas law:
PV = nRTPV=nRT
Values:
P_{max} = 240 kPaP
max
=240kPa
P_{i} = 200 kPaP
i
=200kPa
these two pressures are gauge pressures, which means the actual pressure is benchmarked to 1 atm, which is 101.325 kPa. For consistency, we add that to our given pressures so that we solve for the actual pressure.
P_{max} = 240 kPa + 101.325 kPa = 341.325 kPaP
max
=240kPa+101.325kPa=341.325kPa
P_{i} = 200 kPa + 101.325 kPa = 301.325 kPaP
i
=200kPa+101.325kPa=301.325kPa
We also convert the temperatures to Kelvin, since this is the basic unit for ideal gases:
T_{i} = 23 \textdegree C = 296 KT
i
=23\textdegreeC=296K
T_{max} = 80 \textdegree C = 353 KT
max
=80\textdegreeC=353K
m_{i} = 0.11 kgm
i
=0.11kg
R_{air} = 0.28707 \frac{kJ}{kg K}R
air
=0.28707
kgK
kJ
,
since we're using this constant, it's safe to change the n in the equation to m, as in mass.
First thing we need to do is solve for the volume of the tires initially. We're gonna need this since this is going to be a useful constant throughout the solution. Again, ideal gas law's gonna be perfect for it:
PV = mRTPV=mRT , we need volume so we twist it around to get a solution for volume
V = \frac{mRT}{P}V=
P
mRT
,
We plug in the values at the start of the trip to solve this:
V = \frac{m_i R_{air}T_i}{P_i}V=
P
i
m
i
R
air
T
i
V = \frac{(0.11 kg)(0.28707 \frac{kJ}{kg K})(296 K)}{301.325 kPa}V=
301.325kPa
(0.11kg)(0.28707

V= \frac{(0.11 kg)(0.28707 \frac{kJ}{kg K})(296 K)}{301.325 \frac{kJ}{m^3}}V=

V = 0.03102 m^3V=0.03102m

For a)
We plug in this V to get the mass at the point of the trip where her tires got 240 kPA at 80 °C:
m = \frac{P_{max} V}{R_{air} T_{max}}m=
R
air
T

P

V
m = \frac{(341.325 kPa)(0.03102 m^3)}{(0.28707 \frac{kJ}{kg K})(353 K)}m=
(0.28707
kgK
kJ
)(353K)
(341.325kPa)(0.03102m

)
m = \frac{(341.325 \frac{kJ}{m^3})(0.03102 m^3)}{(0.28707 \frac{kJ}{kg K})(353 K)}m=
(0.28707
kgK
kJ

(341.325

3
kJ
)(0.03102m
3
)
m = m_f = 0.10448 kgm=m
f
=0.10448kg
We subtract this mass to the initial mass to get the actual mass loss in the tires:
\Delta m = m_i - m_f = 0.11 kg - 0.10448 kg = 0.005517 kgΔm=m
i
−m
f
=0.11kg−0.10448kg=0.005517kg
∴ the mass loss in the tires is 0.005517 kg
For b)
We apply the final mass to solve for the pressure after the relief:
P = \frac{m_f R_{air} T}{V}P=
V
m
f
R
air
T
P = \frac{m_f R_{air} T}{V}P=

P = \frac{(0.10448 kg) (0.28707 \frac{kJ}{kg K}) (296 K)}{0.03102 m^3}P=
0.03102m
3
(0.10448kg)(0.28707

∴ P = 286.20083 kPa (actual pressure), 184.876 kPa (gauge pressure)
