24. What does the thermal energy of an object depend upon?
A. The temperature and arrangement of the particles in that object.
B. The temperature, weight, and number of particles of that object. ****
C. The heat of that object and the density of particles.
D. The heat of that object and how fast it is moving.
25. How is thermal energy transfered?
A. From the object with the least mass to the object with the most mass.
B. From the object with the greater mass to the object with less mass.
C. From the object with the higher temperature to the object with the lower temperature.
D. From the object with the lower temperature to the object with a higher temperature. ****
For 25 think about this. Ice is colder than your hand. Right? If you touch the ice with your finger does the ice get hotter or does your finger get hotter. The ice melts so it gets hotter. Right? So which way is the heat flowing?
To determine the answer to question 24, we need to understand that thermal energy is related to temperature and the arrangement of particles in an object. So, the correct answer would be A. The thermal energy of an object depends upon the temperature and arrangement of the particles in that object.
For question 25, thermal energy is transferred through a process called heat transfer. Heat transfer happens between objects with different temperatures. The transfer occurs from the object with a higher temperature to the object with a lower temperature. Therefore, the correct answer is D. Thermal energy is transferred from the object with the lower temperature to the object with a higher temperature.
24. The thermal energy of an object depends upon:
B. The temperature, weight, and number of particles of that object.
25. Thermal energy is transferred:
D. From the object with the lower temperature to the object with a higher temperature.
