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

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.
