Questions: Question 116 1 pts To totally convert a given amount of mechanical energy into heat is possible. need more information. none of these. impossible. (1)

Solution Steps

The question asks whether it is possible to completely convert mechanical energy into heat. According to the principles of thermodynamics, mechanical energy can be entirely converted into heat through processes such as friction. This is a common occurrence in many mechanical systems where kinetic energy is dissipated as thermal energy.

Given the options:

• Possible: This aligns with the understanding that mechanical energy can be converted into heat.
• Need more information: This is not necessary as the conversion is a well-established concept.
• None of these: This is incorrect as the first option is valid.
• Impossible: This contradicts the principles of thermodynamics.
