When a 120 g sample of aluminum absorbs 9612 of heat energy, its temperature increases from 25°c to 115°c. find the specific heat of aluminum

0.89 J/g°C

Concept tested: Quantity of heat

We are given;

                                                      = 90°C

We are required to calculate the specific heat capacity;

That is;

Q = m × c × ΔT

Specific heat capacity, c = Q ÷ mΔT

                                         = 9612 J ÷ (120 g × 90°C)

                                         = 0.89 J/g°C

Therefore, the specific heat capacity of Aluminium is  0.89 J/g°C

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.
