The energy required to warm 1. 0 kg of ice from −40°c to 0°c given the specific heat of ice is 2090 j/kg°c.. is 83,600 j/kg°C
What is Specific heat?
The amount of energy required to increase a substance's temperature by one degree Celsius per gram is known as its specific heat. Although it can alternatively be expressed in terms of calories, specific heat is often expressed in Joules per gram per degree Celsius (J/g oC). The specific heat capacity, a number that characterizes this chemical property, varies depending on the substance.
The total heat required will be the sum of heat energy needed to change the temperature of ice from –40°C to 0°C.
q (total) = mc (ΔT)
= 1 × 2090 × (0 + 40)
= 2090 × 40
= 83,600 j/kg°C
Therefore the energy required is 83,600 j/kg°C, for the given specific heat of the ice.
