    Answer:

    Explanation:

    The problem provides you with the specific heat of ice, which is said to be equal to

    c

    ice

    =

    0.5 cal g

    1

    C

    1

    =

    0.5

    a

    cal

    g

    C

    As you can see, specific heat is expressed in units of energy, in this case calories, per gram Celsius, which means that a substance’s specific heat tells you how much energy is needed to increase the temperature of

    1 g

    of said substance by

    1

    C

    .

    For ice, you know that if you provide

    0.5

    calories of heat to

    1 g

    of ice you will increase its temperature by

    1

    C

    .

    This is how much heat you need to supply to a given sample of ice for every gram and for every

    1

    C

    increase in temperature.

    To increase the temperature of

    20 g

    of ice by

    1

    C

    , you need to provide it with

    0.5 cal

    for every gram. This will cause its temperature to increase by

    1

    C

    .

    20

    g

    0.5 cal

    C

    1

    1

    g

    =

    10 cal

    C

    1

    For a

    1

    C

    increase in temperature, you have

    1

    C

    10 cal

    As you can see, to increase the temperature of this sample by more than

    1

    C

    you need to provide it with

    10 cal

    of heat for every

    1

    C

    increase in temperature.

    For example, to increase the temperature of

    20 g

    of ice by

    3

    C

    , you need to provide it with
