Answer:
Explanation:
The energy flow in the form of heat is a consequence of a difference in temperatures. When two objects with different temperatures are put in contact, the energy will flow from the object with the highest temperature to the one with the lowest temperature.
In this case, the thermometer first had a temperature of 22ºC. Then it was placed in a beaker of water and it read 45ºC. Therefore, the temperature gained by the thermometer is a consequence of the transmission of heat from the water in the beaker, which was at a higher temperature.
