Jessica places 1000 g of water at 20.0°C in an insulated cup. The speciic heat capacity of water is 4.20 J/g • °C. What is the inal temperature of the water if 5000 J of energy is added to the water in the insulated cup?

The temperature change can be calculated using the formula: q = mcΔT. Solving for ΔT gives ΔT = q / (mc). Substituting the given values: ΔT = 5000 J / (1000 g * 4.20 J/g°C) = 1.19°C. Adding this to the initial temperature: 20.0°C + 1.19°C ≈ 21.2°C.
