The specific heat capacity of graphite is 0.71 j/g°c. calculate the energy required to raise the temperature of 750 g of graphite by 160°c.
show your work.

Answer : The energy required will be, 85200 J

Solution :

Formula used :

where,

Q = heat required = ?

m = mass of graphite = 750 g

c = specific heat capacity of graphite =      

 =

Now put all the given values in the above formula, we get heat required.

Therefore, the energy required will be, 85200 J

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.
