It takes 770 joules of energy to raise the temperature of 50.0 g of mercury by 110°c. what is the specific heat capacity of mercury?

0.14 J/g°C.

Explanation:

The amount of heat absorbed by Hg = Q = m.c.ΔT.

where, m is the mass of Hg (m = 50.0 g).

c is the specific heat capacity of Hg = ??? J/g°C.

ΔT is the temperature difference = (final T - initial T = 110.0°C).

∴ The amount of heat absorbed by Hg = Q = m.c.ΔT = 770.0 J.

∴ 770.0 J = (50.0 g)(c)(110.0°C).

∴ c = Q/m.ΔT = (770.0 J)/((50.0 g)(110.0°C) = 0.14 J/g°C.

the answer is c i believe

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.

hope this .
