//Input data
h=50;//The height from which water falls in metres
m=100;//Let us assume the mass of the water in gms
g=980;//Gravitational constant in gms/s^2
J=4.2*10^7;//The mechanical equivalent of heat in ergs/calorie
//Calculations
h1=h*100;//The height from which water falls in cm
W=m*g*h1;//The work done in ergs
t=W/(J*m);//The rise in temperature of water in degree centigrade
//Output
printf('The rise in temperature of water is t = %3.3f degree centigrade ',t)
