The volume of 60 g of a substance is `"20 cm"^2`. If the density of water is `1 "g/cm"^3`, will the substance sink or float in water?

Answer

To determine whether the substance will sink or float in water, we need to follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Information:**
- Mass of the substance = 60 g
- Volume of the substance = 20 cm³ (Note: The original question had a typo; it should be cm³, not cm²)
- Density of water = 1 g/cm³

2. **Calculate the Density of the Substance:**
- The formula for density (ρ) is given by:
\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]
- Substitute the values:
\[ \text{Density of substance} = \frac{60 \text{ g}}{20 \text{ cm}^3} = 3 \text{ g/cm}^3 \]

3. **Compare the Densities:**
- Density of the substance = 3 g/cm³
- Density of water = 1 g/cm³

4. **Determine if the Substance Sinks or Floats:**
- Since the density of the substance (3 g/cm³) is greater than the density of water (1 g/cm³), the substance will sink in water.

### Final Answer:
The substance will sink in water.
