• chemical energy into mechanical
• thermal energy into mechanical

A group of students are studying the movement of thermal energy. The teacher asks the students to place the palms of their hands flat on their table tops and describe what is happening. Which statement below is the best description of what is happening? 

• The table feels cold because it is at a lower temperature than the students' hands, and thermal energy is being pulled into the table. 
• The table feels cold because it is at a lower temperature than the students' hands, and thermal energy is being pulled into the students' hands. 
• The table feels cold because it is solid, and solids hold thermal energy better than air. 
• The table feels cold because it is at a lower temperature than the air in the room. 

Mechanical Energy is transferred to _____ Energy.

• Solar
• Mechanical
• Electrical
• Potential
