Question

A sample of ethyl alcohol absorbs 6.0 × 10^4 J of thermal energy as it boils and completely evaporates. What is the volume of the ethyl alcohol?

Solution

To answer this question, we need more information such as the specific heat of ethyl alcohol, its boiling point, and its latent heat of vaporization.

However, if we assume that all the absorbed thermal energy is used for the phase transition from liquid to gas (evaporation), we can use the formula:

Q = mL

where: Q is the heat absorbed, m is the mass of the substance, and L is the latent heat of vaporization.

Rearranging the formula to find the mass gives:

m = Q / L

Once we have the mass, we can find the volume using the formula:

V = m / ρ

where ρ is the density of the substance.

Without the specific values for L and ρ, we cannot calculate the volume.
