A 3.84-kg block of ice at 0.0°C is heated until it turns into water at 68.5°C. How much heat is used in the process?

Heat required to raise the temperature of ice is given as

Explanation:

Heat required to raise the temperature of the object is given as

here we know that

m = 3.84 kg

L = 335000 J/kg[/tex]

s = 4186 J/C K

now we have

vapour or gas assuming atmospheriv pressure

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
