Під час свердлення внутрішня енергія свердла збільшується завдяки теплопередачі Г. Процес теплопередачі можливий тільки за наявності різниці температур

Answer 1

А - верно
Б - неверно
В - неверно
Г - верно

Answer 2

True Statements:

A. Temperature is a measure of the average kinetic energy of molecules. Temperature is a measure of the average kinetic energy of the particles in a substance. It represents the level of thermal energy present in the system.

B. It is possible to measure the temperature of an individual molecule. In certain experimental setups, such as using laser cooling techniques, it is possible to measure the temperature of individual atoms or molecules. However, this is not a common practice in everyday situations.

False Statements:

В. During drilling, the internal energy of the drill increases due to heat transfer. The internal energy of the drill does not increase during drilling due to heat transfer. Instead, the increase in temperature of the drill is primarily caused by the mechanical work done on it, which increases its internal energy. Heat transfer may occur during drilling, but it does not directly cause an increase in the internal energy of the drill.

Г. Heat transfer is only possible when there is a temperature difference. Heat transfer occurs when there is a temperature difference between two objects or regions. The transfer of heat can happen from a higher temperature region to a lower temperature region, or vice versa. Therefore, a temperature difference is necessary for heat transfer to occur.
