if 10 calories of energy are added to 2 grams of ice at - 30°C, calculate the final temperature of the ice.

= - 20°C

Explanation:

The specific heat capacity of ice using the cgs system is 0.5cal/g°C

The enthalpy change is calculated as follows

ΔH=MC∅ where M represents mass C represents specific heat and ∅ represents the temperature change.

10cal = 2g*0.5cal/g°C*∅

∅=10cal / (2g*0.5cal/g°C)

∅=10°C

Final temperature = - 30°C + 10°C = - 20°C
