`A 50` gm lead bullet `(sp. Heat 0.020 cal//g)` is initially at `30^(@)C` . It is fired vertically upward with a speed `84 m//s` On returning to the starting level, it strikes a slab of ice at `0^(@)C` . `(Axx100)` mg of ice is melted. Find the value of `'A'`.

A 50gram lead bullet, specific heat 0.02 is initially at 30^(@) C. It is fired vertically upwards with a speed of 840 m// s . On returning to the starting level, it strikes a cake of ice at 0^(@)C . How much ice is melted ? Assume that all energy is spent in melting ice only. Take latent heat of ice = 80 cal. // gram.

A 50 g lead bullet (specific heat 0.02 ) is initially at 30^(@)C . It is fired vertically upward with a speed of 840 ms^(-1) . On returning to the starting level it strikes a cake of ice at 0^(@)C . How much ice is melted ? Assume that all energy is spent in melting only. Latent heat of ice =336 j g^(-1) .

At 30^(@) C, a lead bullet of 50 g, is fired verticaly upwards with a speed of 840 m/s. The specific heat of leasd is 0.02 cal/ g^(@) C. On returning to the starting level, it strikes to a cake of ice at 0^(@) C. Calcualte the amount of ice melted (Assume all the energy is spent in melting only)

The entropy change in melting 1g of ice at 0^@C . (Latent heat of ice is 80 cal g^(-1) )

The initial temperature of a lead bullet (specific heat 0.02 cal cdot g^(-1) cdot^(@)C^(-1)) of mass 50 g is 30^(@)C . It is projected upwards with a velocity of 840 m cdot s^(-1) . When the bullet falls down to the point of projection, it hits a block of ice. If the temperature of the ice will be transformed into water? Assume that the entire energy is consumed by the ice. The latent heat of fusion of ice = 80 cal cdot g^(-1) .

If steam of mass 100g and temperature 100^(@)C is released on an ice slab of temperature 0^(@)C , how much ice will melt ?
