# How much heat is required to raise 250.0 g of ice at a temperature -15.0°C to 105.0°C?

Sep 4, 2017

We ain't got the necessary data........

#### Explanation:

We have to supply enuff heat to...

$\left(i\right)$ heat ice from $- 5$ ""^@C to $0$ ""^@C

$\left(i i\right)$ melt ice at $- 0$ ""^@C to give water at $0$ ""^@C

$\left(i i i\right)$ heat water from $0$ ""^@C to $100$ ""^@C

$\left(i v\right)$ vaporize water at $100$ ""^@C to give steam.

$\left(v\right)$ heat steam from $100$ ""^@C to $105$ ""^@C

You have supplied none of the data required, the specific heats of ice, water, and steam; the phase transition data. If you can't be bothered to supply the appropriate data, why should we bother to answer your question?
