Question

A chef wants to melt 0.5kg of chocolate.

The chef heats the chocolate over a pan of boiling water. The temperature of
the chocolate increases by 9°C.
The energy transferred to the chocolate was 9450).
Calculate the specific heat capacity of the chocolate.

Answer 1

Answer:The specific heat capacity of a substance can be calculated using the formula:

Q = mcΔT

where:

Q = heat energy transferred (in joules, J)

m = mass of the substance (in kilograms, kg)

c = specific heat capacity (in joules per kilogram per degree Celsius, J/kg°C)

ΔT = change in temperature (in degrees Celsius, °C)

In this case, we are given:

Q = 9450 J

m = 0.5 kg

ΔT = 9°C

We are asked to find c, the specific heat capacity. We can rearrange the formula to solve for c:

c = Q / (mΔT)

Substituting the given values into the formula, we get:

c = 9450 J / (0.5 kg * 9°C) = 2100 J/kg°C

So, the specific heat capacity of the chocolate is 2100 J/kg°C.
