Pasteurisation is one type of food preservation method. Pasteurisation is the process developed by Louis Pasteur, especially to store milk. In pasteurisation, milk is first heated to about 70 degrees Celsius for 15 to 30 seconds. Then it is suddenly chilled and stored. This prevents the growth of microbes. Pasteurisation deactivates the microbes and reduces the enzyme activity by reduction of temperature.

Sia ? 6 years, 5 months ago

The base of an isosceles triangle = {tex}\frac{4}{3}{/tex}cm
let two equal sides are = x
perimeter of the triangle = {tex}4\frac{2}{{15}}{/tex}cm
perimeter of the triangle = sum of all sides
{tex}62/15 = x +x+4/3{/tex}
or, {tex}62/15=2x+4/3{/tex}
or, {tex}62/15 =(6x+4) /3{/tex}
By crossmutliply,
or, {tex}186= 90x +60{/tex}
or, {tex}186 -60 =90x{/tex}
or, {tex}126= 90x{/tex}
or, {tex}126/90 = x{/tex}
or, {tex}7/5 = x{/tex}
{tex}1\frac{2}{5}cm{/tex} = {tex}x{/tex}

Meghna Thapar 5 years, 10 months ago

The amount of heat energy produced on complete combustion of 1 kg of a fuel is called its calorific value. The calorific value of a fuel is expressed in a unit called kilojoule per kg (kJ/kg). The calorific value of wood is 17000 - 20000 whereas the calorific value of LPG is 55000. Hence, LPG is more efficient than wood.

Any five metals and non metals and thier chemical and physical proprtise

Meghna Thapar 5 years, 10 months ago

Metals - Sodium, potassium, magnesium, aluminium and copper.

Non-metals - Carbon, hydrogen, sulphur, nitrogen and chlorine.

Physical Properties of Metals:

Physical State: All metals are solids at room temperature.

Exceptions: Mercury and gallium are liquids at room temperature.

Lustre: All metals in their pure state have a shine and can be polished to give a highly reflective surface.
Malleability: Metals have the ability to withstand high tensile strength and can be made into thin sheets. This property of metals is called malleability.

Physical Properties of Non-Metals:

Non-metals are either in the solid or gaseous state.

Exception: Bromine is an exception which exists in the liquid state.

Non-metals do not have lustre.

Exception: Iodine crystals are lustrous.

Chemical Properties of Metals:

Reaction of Metals with Oxygen: Almost all metals react with oxygen to form metal oxides.

Metal + Oxygen → Metal oxide

ii. Reaction of Metals with Water: Metals react with water to produce metal oxides with the release of hydrogen gas. But all metals do not react with water.

Metal + Water → Metal oxide + Hydrogen
