Many people have a tendency to think that heat and temperature are the same thing. However, this is not true. Heat describes A.

energy that flows from warmer objects to cooler objects. B. the average amount of energy possessed by an object due to the potential energy stored in its bonds. C. the average amount of energy possessed by an object due to the motion of its particles. D. energy that flows from cooler objects to warmer objects.

The correct answer is actually  

B) energy that flows from warmer objects to cooler objects.

because temperature is a measure of the average amount of energy possessed by an object due to the random motions of its particles.  Heat is the energy that flows from warmer objects to cooler objects. Heat cannot flow in the opposite direction.

Given is the specific heat of water equal to 4.18 Joule per gram per *C.

This means to raise the temperature of 1 g of water by 1 degree Celsius we need 4.18 joule of energy.

Now, look at the question. We are asked that how much amount of energy would be required to raise the temperature of 25 g of water by (54-50) = 4 degree celsius.

To do so we have formula

Q = m C (temperature difference)

A potential energy diagram is shown.
Vesna [10]

Answer:

25kJ

Explanation:

Given the initial energy to be 30kJ

The energy change from the initial energy to the peak energy = (65-30) kJ

= 35kJ

since the second energy change was a drop in energy it is regarded negative

= (55-65)

= -10kJ

Therefore total energy change

= (35-10)kJ

= 25kJ
