Ethyl alcohol has a latent heat of vaporization of 850 j/g. water has a latent heat of vaporization of 2260 j/g. container a contains 1.0 kg of ethyl alcohol. container b contains 1.0 kg of water. both liquids are brought to a boil. if the same amount of heat is continuously added to each container, which liquid will boil away first?

water
ethyl alcohol
both will boil away at the same time
boiling and condensation will happen at the same rate so neither liquid will boil away

all eukaryotic cell have mitochondria : )

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
