☆ Explanation:
- 1.Measures of the hotness of an object is its temperature.
Temperature is the degree of hotness or coldeness of a body. Temperature is measured by thermometer. The SI unit of temperature is Kelvin (K).
_____________________________
- 2.The range of a clinical thermometer in Celsius scale is 35℃ to 43℃.
Clinical thermometer is used by doctors.It is used to measure body temperature of human beings. Mercury is used in this thermometer . It measures between the temperature range of 35℃ to 43℃.
_______________________________
- 4. Digital thermometer does not used mercury.
Digital thermometers are those thermometer that doesn't use mercury.

- 5. Heat is transferred in liquids by conduction and convection.
Conduction is the process in which heat transfers from the hotter to colder region or between two regions at different temperatures which are in contact with each other.
☃ Transfer of heat by conduction takes place in solids, liquids and gases. ☃
Convection is the process in which heat in solids and liquids transfers from hotter part of a substance to rhe colder part by the actual movement of hot particles.
________________________________
- 6. We receive heat from sun by radiation.
Heat can also be transferred through vacuum through radiation. Thus, energy and heat from rhe sun reaches to us through radiation.

- 7. Heat travels through solid by conduction.
☃ Transfer of heat by conduction takes place in solids, liquids and gases. ☃
Conduction occurs when the molecules acquire energy and vibrate, the increase in energy results in rise in temperature and causes heat to travel.
______________________________
- 9.Dark colours are good conductors of heat.
Dark colours are good conductors of heat as they absorb more radiant heat than white and light coloured objects.
☄ Dark surfaces absorb more heat.
☄ Light/smooth surfaces reflect heat.

☃ Transfer of heat by conduction takes place in solids, liquids and gases. ☃
Conduction is the process in which heat transfers from the hotter to colder region or between two regions at different temperatures which are in contact with each other.
