it is made of glass and calibrated to contain a specific volume of liquids at a specific temperature.

a)

volumetric flask

b)

Erlenmeyer flask

c)

Florence flask

d)

round flask

5.

Is used for mixing, heating, chilling, incubation, filtration, storage, and other liquid-handling procedures. Because of its sloping edges and small necks, the contents may be swirled without spilling, which is useful for titrations and boiling liquids.

a)

Erlenmeyer flask

b)

Florence flask

c)

tong

d)

clip

9.

Aid in the measurement of very small units of substances.

a)

electronic weighing scale

b)

triple beam balance

c)

double beam balance

d)

spring balance

10.

These are utilized for cleansing and sterilization purposes. These bottles are made of plastic and act as a squeeze container with a long spout. They usually contain distilled water, ethanol or deionized water.

a)

spoon

b)

scoop

c)

spatula

d)

measuring scoop

12.

It is also known as Newton meters, are another instrument that helps weigh objects. This device consists of a spring and a hook and works according to Hooke's law. According to Hooke's law, the force exerted on an object is directly proportional to its elongation unless the elastic limit is reached.

a)

spring balance

b)

weighing scale

c)

beam balance

d)

spring scale

13.

It is primarily used in titration reactions and is useful for delivering known quantities of substances to other appliances. This device is a long stepped tube with a stopcock at the bottom. It is usually available in 10ml, 25ml, or 50ml sizes.
