The table shows the specific heat capacities of various substances. Which substance requires the least energy to heat it by 1°C?

To determine which substance requires the least energy to heat it by 1°C, we need to look at the specific heat capacities provided in the table. The specific heat capacity is a measure of the energy required to raise the temperature of a unit mass of a substance by 1°C.

The substance with the lowest specific heat capacity will require the least amount of energy to heat it by 1°C.

1. Identify the Specific Heat Capacities: Review the values listed for each substance.
2. Compare the Values: Find the lowest value among the specific heat capacities.
3. Conclude: The substance with the lowest specific heat capacity value is the one that requires the least energy to heat it by 1°C.

If you provide the specific heat capacities from the table, I can help identify the substance that fits this criterion.
