How much heat, in joules and in calories, is required to heat 28.4g ice cube from -23 to -1

Given:

Mass of ice cube, m = 28.4 g

Initial temperature, T1 = -23 C

Final temperature, T2 = -1 C

To determine:

Heat required to raise the temperature from T1 to T2

Explanation:

Heat required (Q) is given as:

Q = mcΔT = mc(T2-T1)

where c = specific of ice (water) = 4.182 J/g C

Q = 28.4 * 4.182*(-1-(-23)) = 2612.9 J

Since 1 J = 0.239 cal

The corresponding Q = 0.239*2612.9 = 624.48 cal

Ans: Q = 2612.9 J

        Q = 624.4 cal

i think its 5049.

i hope this !
