Calculate the amount of heat (in kj) required to raise the temperature of a 88.0 g sample of ethanol from 298.0 k to 405.0 k. the specific heat capacity of ethanol is 2.42 j/g⋅∘c.

Given:

Mass of ethanol m = 88 g

Initial temperature T1 = 298 K = (298-273)C = 25 C

Final temperature, T2 = 405 K = (405-273) = 132 C

heat capacity of ethanol, c = 2.42 J/g C

To determine:

The heat required to raise the temperature of ethanol

Explanation:

the heat (Q) required is given as:

Q = mcΔT = mc(T2-T1)

Q = 88.0 g * 2.42 J/gC *(132-25) C = 22786 J

Ans: Heat required = 22.79 kJ

the answer is   c.) 1575 j.

explanation:

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
