Question

LUBRICATION and THERMAL INSULATION are used to... INCREASE unwanted energy transfers DESTROY energy REDUCE unwanted energy transfers CREATE energy

Answer 1

REDUCE unwanted energy transfers

Answer 2

## Step 1: Understand the purpose of lubrication and thermal insulation. ### Lubrication: Lubrication is used to reduce friction between moving parts. Friction is a force that opposes motion and generates heat, which is an unwanted energy transfer. ### Thermal Insulation: Thermal insulation is used to reduce the transfer of heat between objects or environments. This helps in maintaining desired temperatures and reducing unwanted heat loss or gain. ## Step 2: Analyze the options provided in the question. ### Option 1: INCREASE unwanted energy transfers - This is incorrect because both lubrication and thermal insulation aim to reduce unwanted energy transfers. ### Option 2: DESTROY energy - This is incorrect because energy cannot be destroyed; it can only be transformed from one form to another. ### Option 3: REDUCE unwanted energy transfers - This is correct because both lubrication and thermal insulation are used to minimize energy losses due to friction and heat transfer, respectively. ### Option 4: CREATE energy - This is incorrect because neither lubrication nor thermal insulation creates energy; they only manage the transfer of existing energy. ## Step 3: Conclude that the correct answer is the one that aligns with the purpose of lubrication and thermal insulation.
