In a water-fall the water falls from a height of 100 m . If the entire K.E. of water is converted into heat, the rise in temperature of water will be

A

0.23°C

B

0.46°C

C

2.3°C

D

0.023°C

Text Solution

Verified by Experts

The correct Answer is:
A
mgh = `ms Delta theta`
mgh `= m xx 4.2 xx 10^(3) xx Delta theta`
`rArr Delta theta = (9.8 xx 100)/(4.2 xx 10^3) = 0.23^(@) C`.
