Q=mgh         h=Q/mg =(1.25x106)/(70x9.8)= 1822 m
The number of stairs=1822/0.25= 7288 stairs.

Specific heat of water
Specific heat capacity of water =4186 J/Kg.K    (high value) means:.
Water has higher capacity to store heat Energy
Water take large quantities of heat with little change in temperature



CHANGE OF STATE
Matter normally exists in three states: solid, liquid, and gas. 

A transition from one of these states to another is called a change of state. 
Note the temperature of ice (0 °C). Start heating it slowly on a constant heat source. Note the temperature after every minute. 
Continuously stir the mixture of water and ice. Draw a graph between temperature and time (Figure). 
It will observe no change in the temperature so long as there is ice in the beaker. In the above process, the temperature of the system does not change even though heat is being continuously supplied. 
The heat supplied is being utilized in changing the state from solid (ice) to liquid (water).
The change of state from solid to liquid is called melting and from liquid to solid is called fusion. 
It is observed that the temperature remains constant until the entire amount of the solid substance melts. 
That is, both the solid and liquid states of the substance coexist in thermal equilibrium during the change of states from solid to liquid. 
The temperature at which the solid and the liquid states of the substance in thermal equilibrium with each other is called its melting point. 
It is characteristic of the substance. It also depends on pressure. 
The melting point of a substance at standard atmospheric pressure is called its normal melting point.

Latent Heat 
The amount of heat per unit mass transferred during change of state of the substance is called latent heat of the substance for the process. 
The heat required during a change of state depends upon the heat of transformation and the mass of the substance undergoing a change of state. 
Thus, if mass m of a substance undergoes a change from one state to the other, then the quantity of heat required is given by:
Q = m L 	or 	L = Q/m 
The value of L also depends on the pressure. Its value is usually quoted at standard atmospheric pressure. 
The latent heat for a solid-liquid state change is called the latent heat of fusion (Lf). 
For a liquid-gas state change is called the latent heat of vaporization (Lv). 
These are often referred to as the heat of fusion and the heat of vaporization.

Melting: Conversion of solid into liquid state at constant temperature is melting. 
Evaporation: Conversion of liquid into vapour at all temperatures (even below boiling point)
Boiling: When a liquid is heated gradually, at a particular temperature saturated vapour pressure of the liquid becomes equal to a
