4748 J heat is required to raise the temperature of 150g of ice from -30°C to -15°C.
What is specific heat capacity?
The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases by 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).
Given data :
[tex]T_1[/tex] = -30°C
[tex]T_2[/tex] = -15°C
Use the formula:
Q = mCΔT
Mass of gasoline= 150 g
Specific heat capacity of ice = 2.108 J/g °C.
ΔT = -30 + 15
= 15 °C
Then substitute each given to the formula.
Q = 150 g X 2.108 J/g °C X 15 °C
= 4748 J
Hence, 4748 J heat is required to raise the temperature of 150g of ice from -30°C to -15°C.
