Why do some liquids form a convex surface when placed in a narrow test tube while others form a concave surface​

Chemistry
1 answer:
rewona [7]3 years ago
3 0

Answer:

When liquid water is confined in a tube, its surface (meniscus) has a concave shape because water wets the surface and creeps up the side. ... When liquid mercury is confined in a tube, its surface (meniscus) has a convex shape because the cohesive forces in liquid mercury tend to draw it into a drop.

What is the measure of force per unit area.
Brut [27]

Pressure

Explanation:

Pressure is a measure of force per unit area.

Pressure is defined as the force exerted on a body across a unit area. The unit of pressure is N/m² or Pascal.

                Pressure = \frac{Force}{Area}

The more the force acting on a body the more the pressure felt. A small surface area and a large force increases pressure on a body.

it is right to say that pressure is proportional to force but inversely proportional to area.

Explain how you would make 500ml of a 0.100 m naoh solution
icang [17]
Molar mass NaOH =23+16+1=40 g/mol
<span> 0.100 M= 0.100 mol/L
</span>500 ml=0.500 L
0.500L*0.100 mol/L=0.0500 mol NaOH we need to prepare 500 ml solution
0.0500 mol NaOH*40g/1mol=2 g NaOH we need to prepare 500 ml solution
we need  2 g NaOH, dissolve it in small amount of water, and dilute it with water up to 500 mL
