The specific heat capacity of water is 4.18 J/(g•°C). When 200 grams of water cools from 50.°C to 25°C, the total amount of heat energy released by the water is

The total amount of heat energy released by the water is 20,900 J

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

The sensible heat of a body is the amount of heat received or transferred by a body when it undergoes a temperature variation without there being a change in physical state (solid, liquid or gaseous). Its mathematical expression is:

Q = c * m * ΔT

Where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c and where ΔT is the variation in temperature.

In this case:

Q=?c= 4.18 m= 200 gΔT= Tfinal - Tinitial= 50°C - 25°C= 25°C

Replacing:

Q= 4.18 *200 g* 25°C

Solving:

Q=20,900 J

The total amount of heat energy released by the water is 20,900 J

The bergeron process.

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
