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 nke 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 pressure = 760mmHg = 76cmHg = 1.01325 × 105Pa = 10.336m kọlụm mmiri. 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 (ogwe)
