1.	Calculate the difference in temperature between the water at the top and bottom of Niagra falls of height 500 m assuming that the whole K.E. due to fall is converted into heat. Specific beat capacity of water 4200 Jkg ^(-1) K ^(-1).
Answer» SOLUTION :`Delta W = Delta Q, MGH = mcd T. dT = gh//c = 9.8 XX 500 //4200 = 1.169 K.`
