Calculate the amount of heat required to raise the temperature of a 22-g sample of water from 7 degrees Celsius to 18 degrees Celsius.
Answer (2)
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.
The heat required to raise the temperature of a 22 g sample of water from 7 °C to 18 °C is approximately 1020.608 J. This is calculated using the specific heat formula with a specific heat capacity of water at 4.184 J/g °C. The temperature change is found to be 11 °C.
