Question # 1

Does water and spirit evaporate at the same rate

Ans 1: Evaporation rate of different liquids are different Water and spirit evaporate at different temperature. Form example put a few drops of spirit on hand Drops of spirit will evaporate quickly and the same action will not happen with water The reason is this that the boiling point of spirit lesser than the boiling point of water That is why both spirit water do not evaporate at the same rate

Question # 1

What is meant by thermal expansion

Ans 1: Thermal Expansion: If change in temperature cause the change in length, or volume of a substance then it is called as thermal expansion of that substance.
Ans 2: Examples: When an iron rod is heated, its length changes, which is called its thermal expansion.

Question # 1

How can Celsius scale be converted into Kelvin and Fahrenheit scales

Ans 1: Celsius to Fahrenheit scale: The temperate T on Kelvin scale be obtained by adding 273 in the temperature C on Celsius scale Thus
Ans 2: Celsius to Fahrenheit scale: Since 100 divisions on Celsius scale are equal to 180 division on Fahrenheit scale Therefore, each division on Celsius scale is equal to 1.8 divisions on Fahrenheit scale Moreover correcsponds

Question # 1

What is the effect of temperature on evaporation.

Ans 1: At high temperature more molecules of a liquid are moving with high velocities. Thus more molecules are escaping from its surface The evaporation is faster at high temperature than at low temperature.

Question # 1

Define Latent Heat of fusion?

Ans 1: Heat energy required to change unit mass of a substance from solid to liquid state at it's melting point without change in the temperature is called latent heat of fusion.

Submit

Question # 1

How cooling is produced in refrigerator

Ans 1: Cooling is produced in refrigerators by evaporation of a liquefied gas. This produce cooling effect. Freon, a CFC, was used as a refrigerant gas. Bus its use has been forbidden when it was known that CFC is the cause of ozone depletion in the upper atmosphere which results increase in amount of UV rays from the Sun. The rays are harm ful to all living matter Freon gas is now replaced by Ammonia and other substances which are not harmful to the environment
