1. Where is the spiral located in the electric kettle? 2. Where is the coldest and warmest place in a wooden house? 3. Where should the ice be placed: under the pot or on the pot lid if we want to chill the contents? 4. How does energy flow from the Sun to the Earth and other planets? Why are other types of heat transfer not possible? 5. What color should the refrigerator be painted? 6. Why does the snow melt faster in the city than outside the city? 7. Observations show that insects with dark wings live in high mountain areas.

1. Below, so that the liquid is heated by convection.

2. In summer, the coldest in the basement of the house, the warmest in the attic. In a heated winter, it is warmest where there are heating appliances, i.e. in the rooms. If there is no heating, then it is warmer in the basement than upstairs.

3. If the pan is filled to the brim, then on the lid, if not, then under the pan.

4. By means of various types of radiation – infrared, ultraviolet, visible, X-rays, gamma rays and high-energy particles. Because other types of heat transfer require either direct contact of bodies (thermal conductivity), or a gas or liquid layer between them (convection). In space, there are no gases and liquids between bodies.

5. Into the light.

6. Snow in the city reflects less sunlight, buildings impede the movement of air masses, they have time to heat up, the greenhouse effect, etc.
