A 20-liter cylinder contains 6 atm of gas at 27°C. What would the pressure of the gas be if the gas was heated to 77°C? Ico-consider din po ba yung 20-liter sa pag solve or babaliwalain lang po?
Hindi naman kasi hindi naman din tinanong kung anu magiging final volume at 2 na iyong variable na need mong hanapin.

hello pooo pano po ma convert yung atm to mmHg po? Like parang ganito po " At 20°c a confirmed ammonia gas has a pressure of 2.50 atm. At what temperature would it's pressure be equal to 760 mmHg?
1atm= 760mmHg So, convert mo muna iyong atm sa mmHg 1atm= 760mmHg ==== ====== 2.50 x x= (760)(2.5) x= 1,900mmHg Sunod is lagay na iyong mga given at formula para solve iyong problem P1= 2.50atm or 1900mmHg T1= 20.0 deg C or 293.15 (need iconvert sa Kelvin muna) P2= 760mmHg T2= x P1 = P2 == ===== T1 T2 1900 = 760 == ===== 293.15 x 1900x= 222,794 x= 222,794/1900 x= 117.26 K Converting back to celsius, 117.26K will become -155.89 degrees celsius. Rounding off to the least number of significant figures, which is 2, the answer will be -160 degrees celsius. Kung ang pagkasulat sa 760mmHg ay 760.0mmHg, then the final answer will be -155.9 degrees celsius.
Iattach niyo lang po siya sa solution tapos ma cacancel out din po sila. For example P1= 2.0atm T1= 50°C or 323.15K P2= 10.0atm T2= x 2.0atm = 10.0atm ----------- ------------- 323.15K x 2.0atm(x) = (10.0atm)(323.15K) 2.0atmx = 3231.5atmK x= 3231.5atmK ------------------- 2.0atm "Macacancel out iyong atm" x= 1615.75K Rounding off to the least significant figure, which is 2, ang sagot ay T2= 1,600K
pano naman po pag ganito? Helium gas has a volume of 250mL at 0°C at 1.0atm. What will be the final pressure if the volume is reduced to 100 mL at 45°C

Pano Naman po pag.the helium tank has pressure of 650torr at 25°C what will be the pressure if the temperature tripled
P1= 650 torr
T1= 25°C or 298.15K
P2= x
T2= 894.45K
P1 = P2

x=581,392.5/298.15
x= 1949.99832299178...
The new temperature will be 1950 torr.

iba ibang way pag tuturo ng mga teacher's di ko maiintindihan minsan lang haha
Feel free to ask po para matulungan ko po kayo.
A sample of nitrogen gas has a volume of 478c * m ^ 3 and a pressure of 104.1 kPa. What volume would the gas occupy at 88.2 kPa if the temperature remains constant?
478 cm³ po yan
V1= 478cm^3
P1= 104.1 kPa
V2= x
P2= 88.2 kPa
P1V1= P2V2
(478)(104.1) = 88.2x

Necessary pa po ba yung sa kelvin na 273.15 kasi 273 lang yung tinuro sa amin. Nalilito lang po ako kasi may point 15 pa siyang butal. ;)
Iyong 273.15 po talaga iyong exact kaso kung 273 iyong tinuro sa inyo, edi iyon ang gamitin niyo :)

hello pooo pano po ma convert yung atm to mmHg po? Like parang ganito po " At 20°c a confirmed ammonia gas has a pressure of 2.50 atm. At what temperature would it's pressure be equal to 760 mmHg?
1atm= 760mmHg
So, convert mo muna iyong atm sa mmHg
1atm= 760mmHg
==== ======
2.50 x
x= (760)(2.5)
x= 1,900mmHg
Sunod is lagay na iyong mga given at formula para solve iyong problem
P1= 2.50atm or 1900mmHg
T1= 20.0 deg C or 293.15 (need iconvert sa Kelvin muna)
P2= 760mmHg
T2= x
P1 = P2
== =====
T1 T2
1900 = 760
== =====
293.15 x
1900x= 222,794
x= 222,794/1900
x= 117.26 K
Converting back to celsius, 117.26K will become -155.89 degrees celsius.
Rounding off to the least number of significant figures, which is 2, the answer will be -160 degrees celsius. Kung ang pagkasulat sa 760mmHg ay 760.0mmHg, then the final answer will be -155.9 degrees celsius.
Sirr paano pag ganyan po What will be the pressure if the temperature is tripled?
Magiging triple din po :)
Ano po ung value nung standard temperature????
0°C or 273.15K
Kaso yung teacher namin kailangan dw i-explain yung mga unit kung san galing or kinuha
Iattach niyo lang po siya sa solution tapos ma cacancel out din po sila.
For example
P1= 2.0atm
T1= 50°C or 323.15K
P2= 10.0atm
T2= x
2.0atm = 10.0atm
----------- -------------
323.15K x
2.0atm(x) = (10.0atm)(323.15K)
2.0atmx = 3231.5atmK
x= 3231.5atmK
-------------------
2.0atm
"Macacancel out iyong atm"
x= 1615.75K
Rounding off to the least significant figure, which is 2, ang sagot ay
T2= 1,600K
pano naman po pag ganito?
Helium gas has a volume of 250mL at 0°C at 1.0atm. What will be the final pressure if the volume is reduced to 100 mL at 45°C
P1= 1.0atm
T1= 0°C or 273.15K
V1= 250ml
P2= x
T2= 45°C or 318.15K
V2= 100ml
P1V1 = P2V2
==== =====
T1 T2
1(250) = 100x
==== =====
273.15 318.15
250(318.15)= 100x(273.15)
79,537.5= 27,315x
x= 79,537.5/27,315
x= 2.9118433095368844...
Rounding off to the least number of significant figures, which is 2, the answer will be or final pressure will be 2.9atm.
thank you po!
@@angela24elora Welcome. Thank you din sa pag view :)
ano po ginawa nyo sa 323 at 333? at panu nakuha???
Kinonvert ko po iyong 50 at 60 celsius sa Kelvin by adding 273.15
Need po kasi muna maconvert sa Kelvin
Sir ano po Formula pagang kailangan hanapin is Final pressure p²
Cross Multiply
P1T2
-------- = P2
T1
pano mo nakuha ang mga units? kagaya nang na exchange mo yung atm to mmHg? at pano nag kpa yung mmhg?
Nasa 00:47 po. Kindly check :)
@@mathandlanguagebyjamesjuni salamat po na intindihan ko rin hehehe salamat po!
@@Nanashi_ÆPlays Maraming salamat din po sa pag view :)
i hate math science so much i can't stop crying
Wala parin akong naintindihan😭😭😭😭😭 iba iba kase kayo ng version ng pagtuturo😭😭😭😭😭
Feel free to comment, try ko best sagutan.
