Ntughari nke nkeji ikuku gas

Nrụgide gas bụ nrụgide nke mgbidi na-enye gas, nke bụ ngosipụta macroscopic nke ọnụ ọgụgụ dị ukwuu nke ụmụ irighiri ihe na-aga n'ihu na mgbidi ahụ ma bụrụ ihe dị mkpa dị mkpa iji kọwaa ọnọdụ nke usoro ahụ.Ọtụtụ ihe anụ ahụ na kemịkalụ, dị ka isi ihe, isi ihe na-esi ísì ụtọ, nrụgide vapor, fọrọ nke nta ka ọ bụrụ nrụgide niile dabere.Nrụgide bụkwa ihe dị mkpa n'ịmụ ihe gbasara thermodynamics na kemịkalụ kinetics.Ya mere, nha nke nrụgide dị oke mkpa.

Nkeji a na-ejikarị eme ihe bụ: mmanya (bar), pascal (Pa).Otu nrụgide, na physics, na-ezo aka na ike na-eme kwụ ọtọ n'elu ihe.Nkeji a bụ Pascal (nke akpọrọ Pa Leta bụ “Pa”).(N'ikwu ya n'ụzọ ziri ezi, unit nke nrụgide kwesịrị ịbụ Newton N.) Akụkụ nke nrụgide bụ Pascal, ọ bụkwa omenala ịkpọ nrụgide nrụgide na ndụ) Na China, anyị na-akọwakarị nrụgide gas dị ka "kilogram" (ọ bụghị "jin). ”), nkeji “kg•f/cm2″, bụ otu kilogram nke nrụgide bụ kilogram ike na-arụ ọrụ na centimita square.

1 Standard atmospheric mgbali = 760mmHg = 76cmHg = 1.01325 × 105Pa = 10.336m mmiri kọlụm.1 ọkọlọtọ ikuku mgbali

= 101325 N/㎡.(Ọ na-abụkarị ikuku ọkọlọtọ 1 = 1.01 × 105Pa na mgbako)

Ọ bụrụ na ịchọrọ ịme ngụkọta oge, mmekọrịta dị ka ndị a:

Mmekọrịta mgbanwe nrụgide:

1 dyne kwa centimita square (dyn/cm2) = 0.1 Pa (Pa)

1 torr = 133.322 Pa

1 millimeter nke mercury (mmHg) = 133.322 Pa (Pa)

1 mm kọlụm mmiri (mmH2O) = 9.80665 Pa (Pa)

1 injinịa ikuku ikuku = 98.0665 kilopascals (kPa)

1 kilopascal (kPa) = 0.145 pound agha kwa square inch (psi) = 0.0102 kilogram ike kwa square centimita (kgf/cm2) = 0.0098 atm (atm)

1 paụnd ike kwa square inch (psi) = 6.895 kilopascals (kPa) = 0.0703 kilogram ike kwa square centimita (kgf/cm2) = 0.0689 mmanya ( mmanya) = 0.068 atm (atm)

1 Nrụgide ikuku nke anụ ahụ (atm) = 101.325 kilopascals (kPa) = 14.695949400392 pound ike kwa square inch (psi) = 1.01325 mmanya ( mmanya)
