Which evolves more energy on cooling from 50^∘ C to 10^∘ C: 50.0 g of water or 100 . g of ethano

step 1 Okay, so for this question, they want us to determine which evolves more energy to cool. So the

Which evolves more energy on cooling from 50^∘ C to 10^∘ C:...

Which evolves more energy on cooling from $50^{\circ} \mathrm{C}$ to $10^{\circ} \mathrm{C}: 50.0 \mathrm{g}$ of water or $100 . \mathrm{g}$ of
ethanol $\left(C_{\text {ethanol }}=2.46 \mathrm{J} / \mathrm{g} \cdot \mathrm{K}\right) ?$

Key Concepts

Specific Heat Capacity

Specific heat capacity is a property of a material that indicates the amount of heat energy required to raise the temperature of one gram of that substance by one degree Celsius. It is crucial in determining how substances respond to energy changes during heating or cooling processes.

Heat Energy Calculation

The energy exchanged in a thermal process is calculated by the formula Q = m × c × ?T, where Q represents the heat energy, m is the mass of the substance, c is its specific heat capacity, and ?T is the change in temperature. This formula helps quantify the energy released or absorbed during temperature variations.

Temperature Change

Temperature change (?T) is the difference between the initial and final temperatures during a process, regardless of the substance. It is a key factor in determining the amount of heat energy involved, as it directly scales the energy calculation when combined with mass and specific heat capacity.

Mass

Mass is the quantity of substance and directly influences the total heat energy involved in a temperature change. A larger mass will typically absorb or release more energy compared to a smaller mass for the same change in temperature and specific heat capacity.
