A sample of gas has a volume of 20.0 mL at STP. What will the volume be if the temperature is changed to 546 K and the pressure

Ostrovityanka [42]

The volume did not change, it remained at 20 ml

<h3>Further explanation</h3>

Given

20 ml a sample gas at STP(273 K, 1 atm)

T₂=546 K

P₂=2 atm

Required

The volume

Solution

Combined gas Law :

$\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}$

Input the value :

$\tt \dfrac{1\times 20}{273}=\dfrac{2\times V_2}{546}\\\\V_2=\dfrac{1\times 20\times 546}{273\times 2}\\\\V_2=20~ml$

The volume does not change because the pressure and temperature are increased by the same ratio as the initial conditions (to 2x)

Research three different types of fire extinguisher and explain how these can be used to put out different fires, you must relat

Vilka [71]

The fire triangle is composed of
1) heat
2) fuel
3) oxidizing agent (oxygen)

Types of fire extinguishers:
1) Water and Foam - extinguish the fire by taking away the heat element of the fire triangle. Foam agents separate the oxygen element from the other elements.
2) Carbon dioxide - extinguish fire by taking away the oxygen element of the fire triangle and also be removing the heat with a very cold discharge.
3) Dry Chemical - extinguish the fire primarily by interrupting the chemical reaction of the fire triangle.
4) Wet Chemical - extinguishes the fire by removing the heat of the fire triangle and prevents re-ignition by creating a barrier between the oxygen and fuel elements
5) Clean Agent - extinguish the fire by interrupting the chemical reaction of the fire triangle
6) Dry Powder - extinguish the fire by separating thefuel from the oxygen element or by removing the heat element of the fire triangle
7) Water Mist - extinguish the fire by taking away the heatelement of the fire triangle
8) Cartridge Operated Dry Chemical - extinguish the fire primarily by interrupting the chemical reaction of the fire triangle

ziro4ka [17]

Any physical matter that is obtained or made from plants, animals, or the ground without undergoing a chemical process is called a natural material. This is a true statement.

<h3>Features of natural materials</h3>

Natural materials are the physical matters that are made from plants, animals and ground(environment) which has not been subjected to any chemical processes for modification.

But any natural material that has undergone any chemical process which has been designed and manufactured to fulfil a particular purpose is called a synthetic material.

Therefore, any physical matter that is obtained or made from plants, animals, or the ground without undergoing a chemical process is called a natural material.
