What is the atmospheric pressure in barometer ?
1. What is the atmospheric pressure in barometer ?
The mercury barometer is the standard instrument for atmospheric pressure measurement in weather reporting. The decrease in atmospheric pressure with height can be predicted from the barometric formula. For weather applications, the standard atmospheric pressure is often called 1 bar or 1000 millibars.
2. A gas at 250 K has a pressure of 0.00008 Pa. If the pressure drops to 0.00002 Pa, what is the new temperature?
Jawaban:
If a gas at 250 K has a pressure of 0.00008 Pa and the pressure drops to 0.00002 Pa, 62.5 K is the new temperature
Explanation: -
Initial Pressure P₁ = 0.00008 Pa
Final Pressure P₂ = 0.00002 Pa
Initial Temperature T₁ = 250 K
Since the volume is not mentioned, it remains constant.
So initial Volume V₁ = Final volume V₂
Now using the combined gas equation
\frac{P1 V1}{T1}T1P1V1 = \frac{P2 V2}{T2}T2P2V2
Final Temperature T₂ = \frac{P 2 V2 T1}{P1 V1}P1V1P2V2T1
Plugging in the values,
T₂ = \frac{0.00002 Pa x V2 x 250 K}{0.00008 Pa x V1}0.00008PaxV10.00002PaxV2x250K
As V₂ = V₁, they cancel each other.
T₂ = 62.5 K
3. apa kegunaan dari tyre pressure gauge?
Jawaban:
Tyre pressure gauge atau alat pengukur tekanan ban berfungsi untuk mengukur berapa besar tekanan udara di dalam ban kendaraan.
Penjelasan:
Alat ukur ini sangat dibutuhkan saat mekanik mengecek tekanan udara dalam ban, tanpa alat ini besarnya tekanan udara di dalam ban tidak akan dapat diukur.

5. A student is investigating the pressure that a block of wood is exerting on the floor. The weight of the wood is 20 N. The block is 10 cm long, 5 cm wide, and 2 cm high. a What is the biggest pressure that the block can exert on the floor? b What is the smallest pressure that the block can exert on the floor?
Jawaban:
a. 200 Pa ( Pascal )
b. 40 Pa ( Pascal )
Penjelasan: Well, because the question asked for maximum and minimum pressure,
then we have to find the area of the largest and smallest contact area, on a wooden block there are three variations of the area of the touch area as follows:
Area Of Touch 1 :
→ A¹ = L x W = 10 x 5 = 50cm = 0,5 m
Area Of Touch 2 :
→ A² = L x h = 10 x 2 = 20cm = 0,2m
Area of touch 3 :
→ A³ = W X h = 5 x 2 = 10cm = 0,1 m
Of the three variations of the touch area above, the largest and smallest touch areas are A¹ and A²
Then the maximum pressure is:
→ Pmax = F/A³ = (w x g)/A³
Pmax = 20/0,1 = 200
Then the minimum pressure is:
→ Pmin = F/A¹ = (w x g)/A¹
Pmin = 20/0,5 = 40
I hope this helps (•‿•)

11. What is the effect of pressure and temperature toward the gas particles?
tekanan dan suhu menyebabkan jarak dan interaksi antar partikel gas berubah...
suhu tinggi membuat gerak antar pertikel menjadi lebih besar dan jarak antar partikel mnjadi lbih renggang, akhirnya volume gas membesar dan massajenisnya mengecil.
tekanan yg besar membuat jarak antar partikel menjadi lebih rapat
12. what is the effect of pressure, temperature toward the gas particles?
ketika terjadi perubahan temperatur dan tekanan udara, partikel udara juga terpengaruh, mulai dari pergerakan, massa jenis, dan sebagainya.
semoga bermanfaat..
13. Sebutkan fungsi pressure gauge
Pressure Gauge alat yang digunakan untuk mengukur tekanan fluida (gas atau liquid) dalam tabung tertutup. Satuan dari alat ukur tekanan ini berupa psi (pound per square inch), psf (pound per square foot), mmHg (millimeter of mercury), inHg (inch of mercury), bar, ataupun atm (atmosphere).
14. What is the pressure experienced at a point on the bottom of a swimming pool, 900 centi metres deep? (the density of water is 1.00 x 103 kg / m3 and assume g = 10 ms-2)
The pressure is 9.000Pascals
________________________h = 0,9 m
ρ = 1.000 kg/m³
g = 10 m/s²
P = ρ × g × h
P = 1.000 kg/m³ × 10 m/s² × 0,9 m
P = 9.000 Pa

20. Questions 1. From which hole does the water shoot out with the greatesest force? How can you tell? 2. From which hole does the water shoot out with the least force? 3. The force with which water shoots out from a hole increases as the liquid pressure acting on the water at that point increases. At which hole is the liquid pressure (a) the greatest? ...(b) the least? Conclusion Liquid pressure is greater at... than at... and.... As depth increases, liquid pressure...
Jawaban:
Penjelasan:
The greatest force is in the small cross-sectional area, while the smallest force is in the large cross-sectional area
it can be seen in the equation F = P/A
I don't give you a conclusion because maybe that question have a picture
