The different mechanisms for heat transfer are: Be sure to add a little description for each for study purposes. 6. Temperature is a measure of what type of energy of the individual molecules of a substance? 7. True of False. Most materials expand when they are heated. Does ice expand when it is heated? Yes or No. 8. True or False. Heat is exactly the same as energy. 9. True or False. Internal energy is the sum of all kinetic energy of all the atoms or molecules in a substance. 10.

Answer 1

39 solo - 1) Absoluto Ois (d) Ok 2) AK : (-273+4) = - 2690e 3) we know, ea F-32 = 21 g F-32 = F 21x9 +32 = 69.8 °F 4) 32°F - One 3+273 km 57 There are three type of heat transfer - > Thermal conduction : - heat conduction is the movement of heat from one object to another object That has different temperature when they are touching each other. fi) Connection :- in the connection treat is transfer from one point to another point if the molecule moves itself. it is happen only liquid or gas medium, If there are temperature difference ben two parts then to the molecules itself more from hot to cold Portion 1) Radiation - In This Process heat transter without any medium. From sun we get heat in this Process 67 Temperature is a measure of heat energy of The individual molecules to a substance. 7 Ice is expand when it is heated : False 87 Heat is exactly the same as energy: - True a) Internal energy is the sum of all kinetic energy of all the atoms or molecules in a substance: True 10) Water has a higher heat Capacity.
