chemical apparatus

Beaker

A beaker is a simple container for stirring, mixing and heating liquids commonly used in many laboratories. Beakers are generally cylindrical in shape, with a flat bottom. Most also have a small spout (or "beak") to aid pouring as shown in the picture. Beakers are available in a wide range of sizes, from one millilitre up to several litres.

Erlenmeyer flask or conical flask 

An Erlenmeyer flask or conical flask is a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer, who created it in 1860.

The tapered sides and narrow neck of this flask allow the contents of the flask to be mixed by swirling, without risk of spillage, making them suitable for titrations. Such features similarly make the flask suitable for boiling liquids. Hot vapors condense on the upper section of the Erlenmeyer flask, reducing solvent loss. Erlenmeyer flasks' narrow necks can also support filter funnels.

Flat bottom flask

Basically a flat bottomed flask is just like any other round bottomed flask but can be placed on a flat surface as the flask can sit upright on its own.
They can be used to mix liquids and carry out different chemical experiments just like their round bottomed counterparts. This may involve observing how different chemicals react to each other or when heated with a flame for example.
It can be used to store liquids in a fridge or other location as there is no risk of them falling over and spilling.

Specimen Jar (Gas jar)

These transparent specimen jars used for preserving different specimens in the lab are provided with a cap that fits in tight. These jars provided excellent protection to the species preserved in it.
A container used for collecting gas from experiments. It looks like a tube with a broad base and a broad opening.

MY HOUSE

I have a beautiful house.                              

It is a single storeyed building.

My house consists of a drawing room, dining room, kitchen, bedrooms and bathrooms.

All the rooms are well ventilated and spacious.

There are a good number of flowering plants in front of my house.

There are side walls around my house and a gate.

I play with my neighbours in front of my house.

I help my mother to keep my house neat and clean.

I love my house very much.

गाय

गाय एक महत्त्वपूर्ण पालतू जानवर है जो संसार में प्राय: सर्वत्र पाई जाती है। इससे उत्तम किस्म का दूध प्राप्त होता है। हिन्दू, गाय को 'माता' (गौमाता) कहते हैं। इसके बछड़े बड़े होकर गाड़ी खींचते हैं एवं खेतों की जुताई करते हैं। अहिन्दू लोग गाय का मांस खाते हैं।

 ammeter to voltmeter conversion

You can convert an ammeter into a voltmeter by adding a series resistor.

How to convert voltmeter into ammeter?

voltmeter to ammeter conversion

You can convert a voltmeter into ammeter by adding a parallel resistor with a known value and from that it calculates the current through the resistor. The resistor has to be a very small value, so that it doesn't change the current in the circuit by being placed in line with it.
