Final answer:
The amount of heat required to raise the temperature of the water is approximately 1028.872 J.
Step-by-step explanation:
The specific heat of water is 4.184 J/g °C. To calculate the amount of heat required, we need to use the formula:
Q = m * c * ∆T
Where:
- Q is the heat energy
- m is the mass of the substance (22 g)
- c is the specific heat of the substance (4.184 J/g °C)
- ∆T is the change in temperature (18 °C - 7 °C = 11 °C)
So, plugging in the values, we have:
Q = 22 g * 4.184 J/g °C * 11 °C = 1028.872 J
Therefore, the amount of heat required to raise the temperature of the 22 g sample of water from 7 °C to 18 °C is approximately 1028.872 J.
