9. Concealed heat of ice is 80 calories / gram. Express it in joule / done Please do. Calories .4.18 Joules) Did 10 burns.

Relate on calorie of heat in terms of joule.

A lead bullet just melts when stopped by an obstacle. Assuming that 25 per cent of the heat is absorbed by the obstacle, find the velocity of the bullet if its initial temperature is 27^@C . (Melting point of lead= 327^@C , specific heat of lead = 0.03 calories //gm//^@C , latent jeat of fusion of lead= 6calories//gm,J=4.2 joules //calorie ).

When the state of a system changes from A to B adiabatically the work done on the system is 322 joule. If the state of the same system is changed from A to B by another process, and heat required is 50 calories of heat is required then find work done on the system in this process? (J = 4.2 J//cal)
