Answer:
q = m x Cp x ΔT
Step-by-step explanation:
In the range of temperatures from 15°C to 95°C, water is in the liquid phase. So, the heating process is within the liquid phase and does not involve a change of phase. Therefore, the equation used to calculate the heat absorbed (q) is:
q = m x Cp x ΔT
Where m is the mass of water, Cp is the specific heat of water and ΔT is the change of temperature (in this case: 95°C - 15°C = 80°C).
