    At constant pressure 200 g of water is heated from 10°C to 20°...
    °C to 100°C. The heat energy required is:

    The specific heat capacity of water is 4.184 J/g°C.

    The heat energy required to raise the temperature of a substance can be calculated using the formula:

    Q = m × c × ΔT

    Where:
    Q = heat energy (in Joules)
    m = mass of the substance (in grams)
    c = specific heat capacity of the substance (in J/g°C)
    ΔT = change in temperature (in °C)

    In this case, we have:

    m = 200 g (mass of water)
    c = 4.184 J/g°C (specific heat capacity of water)
    ΔT = 100°C - 10°C = 90°C (change in temperature)

    Substituting these values into the formula, we get:

    Q = 200 g × 4.184 J/g°C × 90°C
    Q = 75,192 J

    Therefore, the heat energy required to heat 200 g of water from 10°C to 100°C at constant pressure is 75,192 J.
