Question 5- Short Answer Type Questions.
 
(i) State the condition which determines the direction of flow of heat.
Answer- Heat always flows from hot body (high temperature) to cold body (low temperature).
 
(ii) What is clinical thermometer? Write its range.
Answer- Clinical thermometer is used to measure temperature of human body. Its range is from 35ºC to 42ºC.
 
(iii) What is the use of kink in a clinical thermometer?
Answer- Kink prevents the level of mercury to fall down even after it is taken out of mouth.
 
(iv) What is lab thermometer? Write its range.
Answer- Laboratory thermometer is used to measure temperature of objects other than living bodies. Its range is usually from -10ºC to 110ºC.
 
(v) Why do we prefer dark clothes in winter and light one in summers?
Answer- Dark coloured clothes are better absorbers of heat than the light coloured clothes. So we prefer dark clothes in winter and light one in summers.
 
(vi) Why do we wear woolen clothes in winter?
Answer- Wool has air trapped inside; air is bad conductor of heat. So woolen clothes keep us warm in winters.
 

Question 6- Long Answer Type Questions.
 
(i) What are various modes of heat transfer? Explain.
Answer-
(1) Conduction- The process by which heat is transferred from hotter end to the colder end of a sold body without actual movement of particles is known as conduction.
(2) Convection- The process of heat transfer due to actual movement of heated particles is called convection.Liquids and gases get heated by convection.
(3) Radiation-   The process of heat transfer which does not require any medium is known as radiation. Heat of the sun reaches earth by radiation.
 
(ii) Explain the formation of sea breeze and land breeze in coastal areas.
Answer- During day time land gets heated due to sunlight. The air over the land gets heated, expands and rises upwards. The cooler air from the sea rushes towards the coast to take its place due to convection. This moving air is known as sea breeze.
During the night time, exactly the reverse happens. Due to its higher absorption capacity, the water cools down more slowly than the land, so cool air from the land move towards the sea, this moving air is known as land breeze.
