Alex is conducting an experiment to find the specific heat capacity of water. She finds that 90 kJ were needed to raise the temperature of 350 g of water from 25°C to 75°C. What equation should she use to calculate the specific heat capacity?

Sagot :

The equation that she will use to calculate the specific heat capacity is Q/(mΔθ).

What is specific heat capacity?

Specific heat capacity is the quantity of heat required to raise 1 kg unit mass by 1 kelvin temperature.

Q = mcΔθ

where;

  • Q is quantity of heat required
  • m is mass of the water
  • c is the specific heat capacity
  • Δθ is change in temperature = 75 - 25 = 50°C

c = Q/(mΔθ)

c = (90,000) / (350 x 50)

c = 5.143 J/g°C

Thus, the equation that she will use to calculate the specific heat capacity is Q/(mΔθ).
