Answers
Answer:
1 The houses in Rajasthan are painted to reflect the sunlight or rather not to absorb the heat by the walls of the house ....so that there is no transfer of heat from outside to inside of the house and thus the temperatur inside the house is less than outside..
2The three basic modes of how heat generated at the chip surface dissipates to the ambient environment are conduction, convection, and radiation, and are described below: Conduction: Heat transfer occurs due to direct contact of matter
3 Convection causes sea breeze and land breeze. Heat transfer through fluids takes place by the process of convection.
4 the outer coat of the penguins of antarctic black as it absorbs more heat from surrounding and provide heat or keep the body warm.
5As you know hot air Rises up and cold air settles down so room heater is placed near to the floor so that the heat can move uniformly from down to up
