### Row 1
Explanation
## Step 1: Understand the Question### The question asks us to compare incandescent bulbs with compact fluorescent bulbs in terms of efficiency and the type of electromagnetic radiation they produce more of. We need to complete the statement: "Relative to compact fluorescent bulbs, incandescent bulbs are __ efficient and produce more __ electromagnetic radiation."## Step 2: Analyze the Statements### From the given statements:1. A 20 W compact fluorescent bulb produces as much light as a 75 W incandescent bulb, indicating that compact fluorescent bulbs are more energy-efficient.2. Compact fluorescent bulbs remain cool while operating, whereas incandescent bulbs do not, suggesting that incandescent bulbs convert more energy into heat.3. Up to
of the energy emitted by incandescent bulbs is thermal energy, whereas only
of the energy emitted by compact fluorescent bulbs is thermal energy. This further supports that incandescent bulbs are less efficient because they waste more energy as heat.## Step 3: Determine the Correct Row from the Table### Based on the analysis:- Incandescent bulbs are less efficient (since they waste more energy as heat).- They produce more infrared radiation (as most of their energy is converted to heat, which is emitted as infrared radiation).### Therefore, we need to find the row that pairs "less" with "infrared." According to the table details:- Row 1 has "less" - "infrared."
