120.0g of ice is melted, how much energy is absorbed?
q = mass x heat fusion.
To determine the energy absorbed when a certain amount of ice melts, we need to use the concept of heat transfer and the specific heat capacity of ice.
The formula to calculate the energy absorbed is:
Energy Absorbed = mass of ice (in grams) × specific heat capacity of ice × change in temperature
Given:
Mass of ice = 120.0 g
Specific heat capacity of ice is approximately 2.09 J/g°C (or 4.18 J/g°C, depending on the source, but for simplicity, we'll use 2.09 J/g°C here)
Change in temperature:
- Ice starts at 0°C
- Ice melts at 0°C (no temperature change during melting)
Substituting these values into the formula:
Energy Absorbed = 120.0 g × 2.09 J/g°C × 0°C
Energy Absorbed = 0 J
Therefore, when 120.0g of ice melts, it absorbs 0 Joules (J) of energy since there is no temperature change during the melting process.
