How much work (in J) is required to expand the volume of a pump from 0.0 L to 2.2 L against an external pressure of 1.2 atm

267.498 J is required to expand the volume of a pump from 0.0 L to 2.2 L against an external pressure of 1.2 atm

Explanation:

The volume change work of a gas is the work necessary for the gas to go from an initial volume Vi to a final volume Vf. If the volume decreases, the gas will have been compressed and it is a compression work; whereas if the volume increases, the gas will have expanded and it is expansion work.

The work is calculated by:

W= - P*ΔV= -P*(Vfinal - Vinitial)

In this case:

Replacing:

W= -121590 *0.0022 m³= - 267.498 N*m= -267.498 J

267.498 J is required to expand the volume of a pump from 0.0 L to 2.2 L against an external pressure of 1.2 atm

answer: mercury

explanation:

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
