Explanation:
Newton's 1st law: An object in motion stays in motion, and an object at rest stays at rest, until acted upon by an unbalanced force.
Newton's 2nd law: Force equals mass times acceleration.
Newton's 3rd law: For every action, there is an opposite and equal reaction.
Compared to coffee at room temperature, the molecules of the coffee at 34°C will be moving faster and colliding with one another more frequently.
The amount of heat needed to increase the temperature of a substance by

is given by

where
m is the mass of the substance

the specific heat capacity

the increase in temperature
In our problem, the mass of the water is m=750 g, the specific heat is

and the amount of heat supplied is

, so if we re-arrange the previous formula we find the increase in temperature of the water:
